Mitsubishi Lancer Evolution IX GT-A Wagon 

I don't know about you, but when I think of a wagon, I normally think of a car that's had the thrill factor turned down a notch or two. Not here. The Lancer Evolution Wagon is a fully-blown Evo in every detail. Dropped onto the same four-wheel- drive platform as the Evo IX, this luggage-lugger is about as extreme as they come.

Outside, it's no raving beauty with its Volvo-esque rear end grafted onto the chunky, sharp-edged Evo front. Inside the story's much the same. Except for the leather-wrapped gear-shifter and three-spoke steering wheel, and the supportive Recaro seats, bland grey plastic is the order of the day. Fortunately, when you fire up that 2-litre turbo it all starts to get rather more interesting.

The Wagon gets the same turbocharged 2-litre engine that debuted in the Evo IX saloon, complete with its sophisticated MIVEC variable valve timing system, but uniquely has the option of an automatic transmission to supplement the standard and excellent six-speed manual.

Bottom-end torque response is beefy and comes on hot and strong from 2500rpm, while at the top-end you can enjoy a deluge of free-flowing revs. That's the beauty of the MIVEC system, in that it allows you ready access to the considerable all that the engine has to give, but if you're stuck in slow-moving city traffic it gives you the luxury of shunt-free progress. The six-speed manual has deliciously short throws and is ideally matched to the engine's torque curve. So how fast is the Evo Wagon? Around Japan's most popular race track, the 2.1km-long Tsukuba Circuit near Tokyo, it clocked an impressive 1min 7sec, a mere one second off the pace of its booted brother. Just like the saloon, the Evo Wagon employs MacPherson struts on the front and a multi-link on the rear with the same rally-bred body rigidity and Bilstein dampers added for good measure. And just like the saloon, the Wagon feels rock-solid in the corners with minimum body-roll, while the ride quality is noticeably better and more compliant than that of the Evo currently on sale in Europe.

But while the Wagon inherits the four-door's Active Centre Differential (ACD) with the three-way Tarmac/Gravel/Snow control, it doesn't get the Evo IX's highly-rated Super Active Yaw Control (AYC). One Mitsubishi engineer suggested that price was the probable reason for its omission, but this car doesn't really need it. With its squared-off and heightened rear bodywork the wagon hauls an extra 70kg over the rear wheels, which works to improve the car's front to rear weight distribution.

Throw it into a corner and the Wagon turns in fast as the extra kilos at the rear get the tail moving and the nose turned-in, while the front-mounted helical LSD and ACD keep the nose in check. At the limits of adhesion, either understeer or oversteer is there for the taking. With no AYC to get in the way of a good slide, and the extra rear weight making it easier to provoke rear-end breakaway, the Wagon can be chucked into prolonged power-slides all day long. And unlike the four-door, which 'floats' its rear inside tyre in tight, fast corners, you can actually feel all four tyres (Yokohama Advan AO46s) in contact with the road, even through the quick corners.

The Evo IX Wagon was without doubt the fastest- cornering wagon on the planet (at least until new versions of the Audi RS6 and RS4 Avants arrived to challenge its supremacy). But as Mitsubishi maked only 2500 Wagons, none officially destined for export.

Gran Turismo 7 (PS5) - GR Supra RZ v Z Performance v Civic Type R FL5 - Tsukuba Circuit

could a gran turismo girl and a forza motorsport boy ever fall in love

[hirocimacruiser]

I normally associate Mazda's old M2 division with building versions of Roadsters and the AZ-1. I hadn't known about this FD3S RX7 based M2 1020 . Translation of pages below.

M2 1020

Be the first!!

Extreme downforce and traction

It's finally out! Or more accurately, it's finally out!

This is the Infini RX-7 built by M2. Its name is 1020.

The concept is to combine sportiness and comfort that is on par with the Type RZ.

This time, since it was a prototype, I only did a quick run. Still, it was in the 9-second range.

This is no ordinary product. Can you wait until it is released on the market in the fall of 1994?

A quick run at Tsukuba in under 9 seconds!

Original Tuned RX-7

The RX-7 itself is so extreme that it can be called a tuned car. In other words, in exchange for increasing the potential of the car as a sports car, it cuts off drivers below a certain level. It is a super high-performance car, but it is not made for everyone.

This is one of the proud things about owning an RX-7, but it also makes tuning a car like this extremely difficult. I've had over 10 tuned RX-7s, and every tuner I've talked to has said it was easy to tune.

I have never heard of such a thing.

In the midst of all this, Mazda's tuning factory, M2, has announced the release of a tuned car based on the RX-7 called the 1020.

"It's still in the development stage, so please don't drive it at full speed," I persuaded him, but I brought it to the Tsukuba Circuit and test drove it. Of course, I couldn't do a full-speed time attack, but I did a good job of driving a two-seater.

With a little push I was able to get a 9 second time. I felt like I could easily get a 7 second time even in this condition.

Of course it is. The M2 is made up of some of the most prominent members of Mazda's sports car development team. The M2 is made by the creator of the RX-7, who is essentially tuning it himself.

The development concept is also ambitious. It should be faster on the circuit than the Type RZII.

It's also a comfortable sports car that makes long-distance driving a breeze.

This is the RX-7 before the minor change. The exterior features a front bumper and rear spoiler, as well as a lightweight carbon bonnet with an air bulge (this will reportedly be made of aluminum for sale). The wheels and tires are BBS aluminum wheels with 235/40ZR17 front and 255/40ZR17 rear.

The car is fitted with Pirelli P-ZERO tires from Japan. The damper is an M2 tune based on a high pressure gas shock.

The intake and exhaust system remains standard for now.

It is highly likely that the car will be tuned with M2 tuning when it goes on sale. This is a reasonable tuning method, but it will have a larger intercooler and muffler tuning.

I wonder if this will be done.

Looking at the interior, the carbon kevlar bucket seats.

I thought they were the Recaro seats used in the RZ, but they are actually original to the M2.

Contrary to appearances, it's easy to ride

I always get nervous when test driving the RX-7 because its high performance requires precise handling.

However, right after the pit exit, "This car is very fast.

I could sense that this car would be friendly to drivers. This was evident from the very supple stroke of the suspension. Despite the use of high-pressure gas shocks, the initial roll was supple, and the ride felt like it would obey my commands. There was no bad habit of the RX-7 of cutting too much in response to steering inputs, and the steering felt natural.

I tried to step on the accelerator hard when exiting the corner, but it started to slip.

The braking performance was at a fairly high level, and the way it moved was slow. I think this was largely due to the characteristics of the Pirelli tires. After making sure that there were no sudden changes in behavior, I gradually raised the base and started with the "Zhou". I was told that the brakes were equipped with prototype pads, and the effect was in proportion to the pressure applied to the pedal, so the good controllability was also a reassuring factor.

The damper settings have not yet been finalized,

therefore, from the second lap onwards, I consciously increased the cornering speed and found that the setting was a little on the underside.

If you don't load the car fairly firmly into the corner, you will feel the slip angle increase from the middle of the corner. Even when drifting in medium-speed corners such as dunlop corners, the rear feels like it is being pressed down from above, and the front and rear tires slide diagonally.

In terms of grip balance, it seems like the rear is better than the front.

At first glance, the 1020 is fitted with flashy aero parts, but these are the results of wind tunnel testing, and are intended to increase downforce. There is still room for further refinements, so the detailed data doesn't mean much, but the lift coefficient at the rear is said to be negative.

This may be what's working. Surprisingly, I could clearly feel the downforce in the final corner and in the high-speed corners from Dunlop Corner to the second hairpin. In terms of balance, the rear downforce is greater than the front, and it feels like the rear tires are being pressed down. There is clearly a greater sense of contact with the ground for the rear tires.

In the final corner, perhaps due to the damper settings, even if you let off the throttle midway through the corner and try to tail out the rear, it was stiff.

It grips firmly and doesn't slip.

Due to the strong downforce at the rear, the handling is somewhat understated, so it is highly likely that the suspension, including the springs, will be further tuned before it goes on sale.

The next thing is the engine. It is powerful enough as it is, but as you go around the track the engine heats up and the power loss becomes noticeable. In that sense, it would be good to have a larger intercooler and, if possible, a larger radiator. And if you make the exhaust system, that is, the muffler pipes, thicker, you can definitely increase the torque across the entire range.

Lastly, the body rigidity of the pre-facelift RX-7 seems to be lacking compared to the current model. When I asked how they would deal with this, I was told that they were considering installing a roll cage.

The car is already stable and fast enough as it is, so there are high expectations for the performance of the completed M2 1020.

PIC CAPTIONS

The exterior design of the M2 1020 is more aggressive than the 102, but it is not just a case of flashy aero parts; it is an aerodynamic body that has been created through repeated wind tunnel testing. 3● The front bumper has a larger opening for a more powerful design. This also improves the cooling effect. The lip spoiler is likely to be enlarged in the future to increase front downforce. 4● An air bulge opens up into the bonnet. It mainly serves as an air outlet to release heat from the engine compartment. Incidentally, the bonnet hood will be made of aluminum at the time of release. 5● The two front seats are bucket seats. They are made entirely of Kevlar and are original to the M2. They provide excellent holding power. Incidentally, it will also be fitted to the Roadster M2 version to be released in the spring of 1994. 6● The steering wheel around the instrument panel has been changed to a new Momo product, but everything is normal. I would like to see a boost gauge and oil temperature gauge added. 7● The extra-large rear wing is fixed. 8● The tires are Pirelli P-ZERO, 235/40ZR17 at the front and 255/40ZR17 at the rear. They have excellent grip performance, but at the same time, they are characterized by a slow start and are easy to control. They are a tire that can be enjoyed not only on the circuit but also on winding roads. They match well with the car.

Printable laser-emitting droplets offer new display technology

Researchers at the University of Tsukuba have developed an innovative method for rapidly creating laser light sources in large quantities using an inkjet printer that ejects laser-emitting droplets. By applying an electric field to these droplets, the researchers demonstrated that switching the emission of light on and off is possible. Furthermore, they successfully created a compact laser display by arranging these droplets on a circuit board. The study is published in Advanced Materials. Displays for TVs, PCs, and smartphones are continually improving in picture quality, clarity, and energy efficiency. Laser displays are anticipated to represent the next-generation model. Particularly regarding brightness and color reproducibility, laser displays have the potential to overcome the intrinsic limitations of conventional light-emitting devices, such as OLEDs and liquid crystals.
