I wanted a Chevy SS, but it was too expensive so I bought this car instead as a compromise via /r/cars

I wanted a Chevy SS, but it was too expensive so I bought this car instead as a compromise

TL;DR I review the car I got instead of the SS I wanted, ramble for a bit, then list a bunch of alternatives that anyone considering an SS should consider instead

For the absolute longest time, my dream car was a Chevy SS. RWD, manual, 4 doors, magnetic ride, and the whole works. An absolute beauty of a car, and when driving my old Pontiac G8 I looked up to SS owners hoping I could join their prestigious ranks some day. But tragically the $30k+ price point for the manual cars was keeping me away from ownership. But fuck it I was sick of the automatic gearbox in my G8 and wanted to get something.

So I bought this instead

I bought a 2011 Cadillac CTS-V for $24500, and it was the best irresponsible decision I've ever made.

Value/Features

Performance

For the money, the car is absolutely unbelievable value. Like the SS, it has 4 doors, magnetic ride control, RWD, a GM small block V8, and a manual transmission option. But unlike the SS, the CTS-V has a 550 hp supercharged LSA engine while the SS "only" has a 440 hp LS3 engine.

From a performance standpoint, there is little to complain about. The car is insanely fast, even in its stock form. The car handles better than a 4000 lb sedan should. I don't feel comfortable thrashing it like I used to in my Miatas, but I sure as hell love to drive the car hard. I'm not a professional driver and maybe will track the car in the future, but I unfortunately can't give a much better driving perspective on the car beyond "it's good". Magnetic ride control is a delight as well even though my front struts likely aren't working at 100%.

The car had an Air Raid intake that the previous owner installed which makes the supercharger really shout. I love hearing that thing when I get on the gas. On the other hand, the stock exhaust is quiet and in desperate need for an upgrade. The exhaust is the one thing I miss about my old G8, but luckily that can be fixed for a few hundred bucks. Anyone who buys a CTS-V should upgrade their exhaust.

Oh also the car gets 14-16 mpg for most owners. I get just north of 15 with my driving. I got 19.2 while hypermiling the car through Wisconsin after I bought it. Buyers beware that you'll probably never get more than 20 mpg in this car. Even as someone who was used to driving a Pontiac G8 that got 17 mpg on 87 octane, it seriously hurts considering I commute about 40 miles per day round trip and have to fill up more than once a week on average

Interior

While the CTS-V beats the SS from a performance standpoint, the SS has a handful of creature comforts the CTS-V lacks, mainly related to the infotainment/nav along with additional driving assists and a heads-up display. Since I'm trash and have no standards, that doesn't matter to me. The interior is still miles ahead of any car I've ever owned, better than 90% of cars from 2011, and gives modern cars like the SS a run for their money. The way the navigation system retracts when not in use is a feature I think every car should have. The ultraview sunroof is the first sunroof I've ever seen that actually made me like sunroofs. The base sedan seats leave a lot to be desired, and I'll most likely buy some used Recaro seats to fix that.

By far the biggest gripe I have with this car is interior room. The SS can comfortably seat passengers in the back, and the driver will never complain about headroom. Meanwhile the CTS-V has an incredibly low roof for a sedan, which means the rear seat passengers will have to choose between sitting upright with their head in the glass, or slouching with their knees struggling for room. The driver's seat also lacks headroom, so my solution is to recline the seat back. My driving position has been referred to as "cholo" multiple times.

In my opinion the cramped rear seats ruin the main reason I wanted to get a performance sedan. Granted they're still miles ahead of the rear seats in cars like the Mustang or Camaro, but it's just not a pleasant experience, and from my perspective if people aren't eager to ride in the rear seats of my car, they don't have much of a purpose at all.

Let me break out and keep discussing seats, because honestly the rear seats are 99% of the reason I got this car instead of a Corvette or something of that nature. People who are considering a performance sedan, ask yourself why you want a sedan. Ask yourself if you really need a sedan. Everyone I know told me I needed a sedan. I told myself I needed a sedan. But honestly, I go weeks at a time never hauling more than one person in my car. I'm 24 years old and don't intend to have kids remotely soon. 95% of my driving is done by myself. Did I really need a sedan? Do you really need a sedan? Trying to have one car that "does it all" is great, but if you don't carpool, don't have kids, don't sobercab your friends around, and don't drive for Uber, odds are you don't need a sedan as much as you think.

Exterior / Styling

To be brief, I love the look of the car, but I think the car is less of a sleeper than the SS. This may be pros to some people, but I personally don't like it much. The image draws attention, plus it gives me a serious case of imposter syndrome. The car costs less than a new Honda Accord, and I have plenty of friends and coworkers who spent more on their cars, but it still doesn't feel like a car that I should be able to afford as a 24-year-old.

Was it worth the money?

Let's circle back to this price difference. For $24500 I picked up a 2011 CTS-V with only 72000 miles on the clock. Going rate for these cars, especially the manuals, is up for debate. But basically anyone would agree that $24500 is undervalued. So what was wrong with it? Well after about 3 months of ownership I've spent about $1500 on repairs, which included an attempt to fix a pretty severe oil burning issue. When I bought the car it was burning 1 quart of oil ever 500 miles, after running a lot of solvents through it, I've burned less than a quart after about 1800 miles, not good, but not as bad as it was. I also spent another $500 replacing the rear struts, which were completely useless. Replacing those made the magnetic ride control actually work again, and honestly made the car so much more enjoyable. After investing $26000 into this car, I will probably be spending another $1500 on an exhaust and used Recaro seats, putting my grand total at $27500. I could have saved another $4000 and got an SS. I often feel like that would have been a better option. I definitely feel that the better option would have been to save another $10000+ and get one of the cheaper cars I listed below, but not everyone shopping for a CTS-V may be willing to downgrade like I am.

Thoughts Summarized

What do I love about it

Supercharger whine is intoxicating

The car is unbelievably fast, especially for a relatively discrete sedan

The car handles way better than a 9 year old American sedan has any right to

The interior is incredible (as someone with trash standards who has never owned a car newer than 2011)

What don't I love about it

15 mpg with premium fuel

The rear seats are not comfortable

The drivers seat lacks headroom

What am I "meh" about

If you're gonna buy a CTS-V and intend to drive it hard, opt for the recaro seats

Less of a sleeper than the Chevy SS, but still a sleeper regardless

Imposter syndrome.

Alternatives

I don't want this review to come off as me being bitter or upset with the car, because seriously I love it. I'm just a chronic overthinker and love to go over "what-if" scenarios who is giving a critical review of his car.

So to end my ramblings, I love my CTS-V, but if I could do it all over again, there's a handful of other cars I personally think I should have considered, and anyone considering an SS/CTS-V should also consider:

Chevy SS (If I had the patience to hold out for another year) - In my opinion the interior isn't a huge upgrade, but the cabin room and sleeper status is completely worth it. Despite having 110 less horsepower, I know from experience driving both cars that I would have been more than happy with it

BMW 535d - The car is slower than the SS, but about on-par with my G8, can be had for less than $20,000, has AWD, and gets 30+ MPG. The automatic transmission is my main gripe with the car, and if I got one I'd need some sort of weekend car to scratch my manual itch. While it's not in the same league as the CTS-V, I think this car goes toe-to-toe with the G8 for value.

Audi S4 - This is the car I truly believe I should have bought instead of the SS. The B8 models have an interior that's just as good as the SS, and despite the car being smaller than the CTS-V, the interior provides just as much room, if not more, for the drivers and passengers. The car would have cost me less upfront, less to insure, and less at the pump.

Pontiac G8 GXP - In my opinion this car is not worth the money versus an SS or CTS-V. I love the G8 and commodore platform, but people are demanding $25000 minimum for the manual versions. Just get an SS.

Pontiac GTO - The major reason I got my CTS-V and wanted an SS was because I didn't like having an automatic transmission. For less than $10k, you can get a 400 hp LS2 paired with a manual transmission and make all the rumbly V8 noises you'd ever dream of making. Complain about the fact that it's a coupe, but in reality the rear seats aren't any worse than the CTS-V

First gen CTS-V - For those of you who read my GTO description, but really want 4 doors.

Camaro/Mustang - I'm putting these cars in the same category because they are the same. Yeah you can split hairs over them trying to debate which is better, but in the end 90% of the people that buy these cars pick them based on looks or brand loyalty. The 4-cylinder trims sound like a blast as well considering how economical they are.

Cadillac ATS - The 2.0T trim has a manual transmission option. So if you can live with the lack of dignity that comes with not having a V8, it's a great little car. The ATS-V on the other hand hasn't hit a good price:performance ratio for me to recommend it. The CTS-V is a better car for less money.

Corvette - I was seriously considering a C5 or C6, and honestly it's still on my radar. After all this reflecting on the 2-door vs 4-door debate, I've become more reinforced by the idea that I don't actually need a 4-door car. For as little as $10,000 I could get a C5 Corvette and drive the absolute fuck out while laughing my way to the bank with all the money I saved.

I could probably list a dozen more cars, but I think I hit the big points. Odds are my next car will be something cheaper like a C5 Z06 paired with something fun and economical like an ATS 2.0 or Fiat 500 Abarth. For anyone that read this whole thing, thanks for your time.

Video: Tuned BMW E60 535d Takes on Serious Competition on Drag Strip

The days of the diesel engine seem to be numbered. Due to some serious damage done by the Dieselgate scandal, sales of the compression-ignition models are currently taking a turn for the worse, an unexpected turn of events, to be honest. However, some people still love the torque and efficiency of diesel mills, such as the gentleman with this modified BMW E60 535d who not only daily drives this thing but also tuned it to deliver more power.

The aim was to squeeze as much power out of the engine as possible and I’d think he did a great job. In standard guise, the E60 535d would come with a 3-liter straight six, bi-turbo diesel engine good for 272 HP and 560 Nm (413 lb-ft) of torque. Not that bad for those days, but there was definitely a bit more oomph left in there. This particular car claims to be putting out 440 HP and 900 Nm (664 lb-ft) of torque, numbers incredibly high for a car of this age.

Nevertheless, it does deliver some incredible runs against much more powerful and newer rivals on the drag strip. We get to see it take down a Brabus GLE63 S AMG model, it then takes on a Tesla Model S Shooting Brake, a custom version, of course, since the American car maker isn’t making such contraptions. We don’t know which version of the Model S was used as a basis but I reckon it was definitely not a P100D.

This ‘little 5er that could’ also takes on several other BMWs. From an F10 M5 which nearly loses to it, to the brand new F90 M5, which is a proper land rocket and secures an easy win, despite boggling the launch. Even another diesel BMW shows up, a tuned E92 335d, the two setting up a proper smoke show while drag racing.

2018 BMW 5-series Lineup Grows by One (Very Powerful Diesel, That Is)

–

With U.S.-market diesels nixed at Audi and on borrowed time over at Mercedes-Benz, BMW stands to be the only German luxury-brand willing to keep selling them here. And BMW’s latest diesel-burner, the 2018 540d xDrive sedan, is shaping up to be a stunner, with huge helpings of the the torque and fuel economy that give diesel-powered entries their appeal.

–

For starters, the new 540d’s turbocharged 3.0-liter inline-six—which hails from BMW’s new B57 modular engine family—makes 261 horsepower and a massive 457 pound-feet of torque. (Last year, we drove a Euro-spec 530d, which uses the same powertrain but has a different name.) That’s quite a bit more than the 255 horsepower and 413 pound-feet produced by the old N57-family engine, which powers the X5 xDrive35d and was under the previous-generation diesel 5-series’ hood.

–

With BMW’s claim that the 540d runs to 60 mph in 5.1 seconds—a half-second quicker than the last 2014 535d we tested—the 540d likely will be the brand’s quickest-ever diesel car sold here. In fact, it might be among the quickest regular-production diesels sold in America yet.

–

Even so, the diesel 5er sips fuel like a Toyota Corolla—at least on the highway. The EPA’s highway fuel economy estimates for the 540d xDrive land at a solid 36 mpg. The city figure is a respectable 26 mpg, which is more than offset by the stellar highway efficiency to earn the 540d a 30-mpg combined estimate.

–

BMW 5-Series: Reviews, Photos, News, All the Info

–

BMW plans to make this model available only with all-wheel drive (xDrive in BMW-speak) and its ubiquitous eight-speed automatic transmission. (The diesel-powered 3-series, by contrast, is available with rear- or all-wheel drive; the diesel-powered X5 xDrive35d crossover is, like the 540d, all-wheel-drive-only, as will be the upcoming X3 diesel.) Pricing will be rather dear, at $62,995 before options—and between M Sport and Dynamic Handling packages as well as driving-assistance packages and cabin upgrades, it’s easy to end up with a car well over $70,000. And yes, you’ll still need to pony up another $300 up front and $80 a year just to be able to connect your iPhone to the infotainment display via Apple CarPlay. If you’re both flush with cash and an itch for a powerful diesel-fueled sedan, BMW will begin sending 540d models to dealerships in the United States in February.

Video: BMW 530d Versus Mercedes-Benz E350d Acceleration Comparison

Now that BMW officially announced the return of a a diesel-powered 5 Series to the US, it’s time to take a closer look at what that model brings to the table. Dubbed 540d, the car will, however, be quite different from its European counterpart. Whereas in the old continent the 540d uses a twin-turbo 3-liter straight six diesel with 320 HP, the US version will instead be a Euro-spec 530d model under the sheet metal.

That means it will be using a similar 3-liter straight six engine but with less power, rated at 265 HP and 620 Nm (457 lb-ft) of torque. Even so, compared to the old 535d model that used to be on sale in the US before the G30 5er came out, the numbers are an improvement. In case you don’t recall, the old F10 5 Series model had 258 HP and 560 Nm (413 lb-ft) of torque, thus the new one coming out with a noticeable upgrade.

Nevertheless, even though some might be disappointed by the figures of the US-spec 540d, they’ll soon find that it has plenty of power and especially torque under the hood, especially considering the fact that the G30 chassis lost some weight compared to the old F10 model. As the video below proves, the 530d is also faster than its Mercedes-Benz rival, the E350d. The Stuttgart-made sedan comes with a V6 but its 3-liter engine also makes 7 less HP while on the torque front things are evenly matched.

The heavier Merc is seemingly a bit behind the BMW every step of the way as these two rush to reach their electronically limited top speeds in the video below. Of course, we also need to keep in mind that these videos can’t be taken as scientific fact as there are a number of factors to be taken into consideration here.

The truth about Chip-Tuning (VERY long read!) via /r/cars

The truth about Chip-Tuning (VERY long read!)

First off, this is an article from a austrian blog (MotorBlock).

I just took some time to translate it to englisch (as good as i could)

All credit goes to Philipp Stalzer from MotorBlock (article is in german!) Source article

I think many people on here might want to read this, it contains a ton of interesting information on why chiptuning is more bad than good.

I had the thought of tuning my future car as well, but after reading this i think i'll skip that and just let it be stock, since i plan to drive it several years.

____________________________________________________________

The truth about chip-tuning, by Philipp Stalzer

An often discussed Topic, with almost no real technical background or tangible details to make a decision if you want to mess around with your Engine electronics or not. A text that popped up in the internet and with my understanding of Engines it tells us: Stay away from manipulating your ECU! Unfortunately this knowledge does not come around enough, and this is very important for a specific industry. A lot of money is paid for "chiptuning" that would be better invested in getting the bigger engine right from the start.

Truth about Chip-Tuning: in almost all cases, don't do it!

Of course, this text does not apply to all engines out there. There are some Manufacturers that assume that their clients want to get quite more power out of their engines, for example many japanese brands. In a time where cost-reducing was not such a big topic, engineers sometimes used "over-sized" parts in the process. This changed with "Computer Aided Manufacturing" and the growing interest to safe more money in the production of cars/engines.

Infos from a BMW Engine-Technican

Although Manufacturers keep it low when it comes to this topics, a reader of this blog took some time to gather quite some statements of a BWM-Engineer posted in various forums etc. and sum it up. A shortened, but technical very informative and detailed version of this text regarding negative effects of chiptuning (based on BMW diesel-engines) is worth reading for everybody who is planning to chip his engine:

(This part contains some very deep technical info and very specific names wich i can't really translate that well so i simplified this part, some words might sound weird since i could not find proper translations, sorry for that)

I've been working for about 20 years in the engineering of BWM Diesel-engines. The engines of the model series M47/M57 as well as their successors N47/M57 are a bit like my "kids", about 3 patents of those are on my name.

In former times it was possible to engineer an own engine for each car, sometimes even whole lineups for a single car. Today this is not possible anymore. Nowadays you are reliant on so called "equal-parts" - this is the only way to produce engines at a reasonable cost. BMW only produces 6 cylinder engines with 3 liter. To sum up that all of these engines are the same, solely because they have the same displacement, is narrow-thinking and sadly the thinking of the "tuners".

In 1993 the development of modern, direct-injection Diesel-engines began. For this you did not build whole engines, rather there was a so called "master cylinder". For all BMW Common-rail-diesels it was 84mm drilling and a 90mm stroke. Four of those become a 2L Diesel, six get a 3L and eight of them - you guessed it - gets you a V8, that was used for example in a series 7 BMW.

Today there are 3 versions of this cylinder: UL, OL and TOP.

UL stands for lower-performance, the piston is made out of a simple aluminum-alloy, the crankshaft is simple-forged and uses a sintered connecting rod. It can cover up to 25kw/75nm per cylinder and is used in models like the x16d, x18d and x25d (exept the f10 model after 2011)

OL stands for upper-perfomance, the cylinder path is honed several times, it has forged connecting rods and the bearings of the rods and crankshaft are sputtered bearing. It can cover up to 35kw/100nm and is used in models like x20d, x30d.

TOP is for high performance, including a special treated crankshaft as well as laser-treated cylinder-paths. With this it is possible to increase injection-pressure and rated speed. This cylinders are used in models like x23d, 525d (after 2011) and x35d/x40d.

The engines have exact mechanical measuremants, but are different in materials.

For example the OL piston has a higher amount of copper and chrome. The higher amount of copper dissipates heat better out of the chamber into the piston floor cooling. Chrome makes the piston more stable at higher combustion-pressure inside an OL-engine.

Since the pistons are exactly the same sizes, you can however use a OL or TOP piston in an UL engine when doing repairs. This helps saving costs even more by reducing stocks and the prices regarding spare parts are more secondary.

It is correct that manufacturers limit the power output via the ECU (for example in an 25d), but they have to, since the used components are not made for higher hp/nm outputs. Almost every turbocharged diesel-engine is capable of generating more thermal energy than it can handle mechanically, and this is what chiptuning is relying on.

Now here come the tuners with their chips, because they can fetch data/part numbers from After-Sales-Programs (at BMW you can access it without any further requirements) and think all 3L engines are the same. It is true in terms of repairs, but not with newly shipped cars. You can use a piston of a 535d in a 316d and it will fit and work perfectly (same size) but is indeed "overpowered" in terms of materials. In this particular case it will be no problem since a 316d puts out less power than a 535d.

To get a sense of how much money can be saved by using a master cylinder for a complete engine lineup: if a piston "148" for the upper performance costs 12€, an M124 only 8€ that this makes about 24€ per car. For a production capacity of 200.000 cars 525's with 6 cylinder you're looking at a whopping 4.8 Million Euro. And the piston isn't the only thing where money is saved. Because of this, the customer pays less for a 116d as for a 123d, even though they both have a 2L engine wich are basically built the same way. The 116 just has less heat resistant and cheaper materials built in.

No manufacturer limits the power only by electronics. It is the media and especially the tuning-scene that spread this rumor. The differences nowadays not only come down to engine size, it also goes as far as material and single production processes. Same-Part strategy does not mean that the parts are exactly the same, only that the measurements and weights are the same. Also the thermal characteristics are different.

Interesting from a different area: Bosch does the same thing with their machines. You have the green series (for the little handyman at home) and blue series (professional). Products look the same (expept housing color) but here we also have different materiels used. A drilling machine from the blue series has a better hardened transmission, switches are built for far more cycles, overload protection is higher, thicker cables.

Regulating the power output via electronic serves the purpose that the engine with it's simple materials doesn't get overused. Through supercharging you can give any amount of power to a engine, but it will not be able to handle it. So when you think your 118i with its 170hp could do way more, but the stupid people at BMW are just to lazy to get more power out of that engine let me tell you: a 118i is capable of over 300hp, even keeping all emissions in the green zone, but he won't make that for long.

Basically in the automotive industry you can say:

not everything is at it seems

wenn there is a way to save €, it will be done

espacially in the automovie industry many facts from media or magazines/books are incorrect

The statement "how long does my engine last when I chip it" can't be said in miles/km, because a engine does not know the term miles/km. If a M124 operates on the potential of a 30d, but you never or only rarely request the full power, the life expectancy won't change at all. If you floor it a lot and request the full power often, it will come to slight structural changes. Depending on further circumstances your engine can fail after a few minutes, or maybe 1.000 operating hours.

The combustion inside the engine can reach up to 2000°C, aluminum melts at 660°, so it should totally melt, right? Not really, since the peak temperature only last for a very short time and then the piston has an about 10 times longer period to cool off. Above 400°C aluminum looses a lot of its strenght, so the piston temp should be under 400°C at all times. How much it heats up depends on the intensity of the combustion. It peaks at full load and maximum torque, and with chiptuning this only gets much higher. To compensate this you do the following: you increase the amount of copper and chrome in the piston, this gives it better strenght at 420°C. So you can say, that in stock motors with more power there are better alloys used. A quick "tune" via ecu or plugging in a "race chip" can't do that. The thermal capacity of the engine is exhausted, the piston gets weaker the more power you give it in overload range. Worst case is that the top land breaks, and your engine is complete toast.

Regarding damage, these mostly occure long time after the tuning. Usually after 50k-80k km the problems start. Many people do not own the cars anymore by that time, and the subsequent owner doesn't know about the bad suprise that might happen. If a damage is found in the repair shop, they often just change the part and thats it. Often nobody suspects a tuning chip as the main reason (you know.. tuners say "its all good man!)

Also many tuners (and others) love to say the damage comes from weared parts, for example a turbocharger. But that's not it!. Turbos do get damaged by tuning and wrong handling.

I can understand the side of the customer. There comes somebody and puts a little thingy in your car, not even that expensive and suddenly you have a lot more power and more fun. You don't see it, but you feel it. With the thought in the head, that all engines are the same, you think that nothing could go wrong. The tuners do their part to the story... why should they report any damage caused by their tuning, that would ruin their business.

Chiptuning has somewhat in common with smoking. Cigarette-Manufacturers won't tell you that smoking causes lung-cancer. Smokers argue that they know people that smoked for long time and got 80 years old. Is that the evidence that smoking is unhealthy? Also here: Business with curing diseases related to smoking is huge.

All this statements should be valid for almost all Car-manufacturers, i personally don't know any brand that does not use the same-part strategy. Better safe than sorry.
