The Independent Review: Toyota GT86
 
http://www.independent.co.uk/life-st...6-6284861.html

http://www.independent.co.uk/incomin...80/5320374.jpg

Price: From £25,000 (on sale June)
Engine: 1,998cc, flat-four cylinders, 16 valves, 200bhp
Transmission: Six-speed gearbox (six-speed auto optional), rear-wheel drive
Performance: 143mph, 0-62 in under 7 seconds, 42mpg official average, CO2 under 160g/km

"If a car is not fun, it is not a car," said Toyota CEO Akio Toyoda at the Tokyo motor show as he revealed the company's new slogan: "Fun to drive, again."

It is a response to the firm's battering over the past year, which began with a media witch-hunt over the (extremely rare) sticking-accelerator trouble, in which the consumer had to be all-powerful in their right to be incompetent and in which Toyota fell too readily on the corporate sword.

Then there was the Tohoku earthquake followed by the Thai floods, which destroyed the supply chains of every Japanese car company. Against this background, Toyota's new GT 86 comes like a new beginning.

"Car enthusiasts are bored with cars that cost too much in which the driver doesn't do enough and which rely on hugely powerful turbo engines, four-wheel drive and massive grip," says the GT 86's development engineer, Yoshi Sasak. He's right. Technology has taken over, and what are we to do with such ludicrously fast cars? It's not as if we can really enjoy them on public roads.

Here, then, is Toyota's new sports coupé, created in collaboration with Subaru, whose own version is called BRZ. So it has a Subaru-signature flat-four engine, of 2.0 litres and producing 200bhp without the turbocharger usual in fast Subarus. But instead of the now-usual front-wheel drive or Subaru-style four-wheel drive, it has rear-wheel drive.
Among this size and price of sporting coupé, this once-default configuration is now unique. Yet the opportunity it can give for microfine control in a corner is the best configuration for driving fun. Usefully, Subaru already had the four-wheel drive Impreza; remove the drive to the front wheels and you have the basis of the GT 86's underpinnings.

The looks owe a little to the 1960s Toyota 2000 GT, an exotic, slightly E-type-like sports car made famous (once the roof had been chopped off) in the Bond film You Only Live Twice. The "86" part alludes to the riotously entertaining, rear-wheel drive, Toyota Corolla GT Coupé Twin-Cam of the 1980s whose internal codename was AE86. Currently the only sensible-money sports car with a front engine and drive to the rear wheels is the Mazda MX-5, and that's a roadster. So the GT 86 stands alone as the coupé that car nuts have craved for years.

I am pleased to report that all of the promise is fulfilled, and more. The engine is a keen, fizzy thing, its note a mix of rasp and throb, its response instant and wonderfully easy to meter. This, plus crisp, sensitive, natural-feeling steering – it's electrically assisted, amazingly, and surely the best yet of its type – fills the driver with the intoxicating confidence of being fully, entirely in control, even on a damp, slippery test track. More power in a corner brings on a gentle drift, helped by the limited-slip differential; this car does exactly what you want it to, in a way many recently qualified drivers will probably never have experienced before now.

It's fast, but not madly so. You need to work the revvy engine quite hard, but that's part of the fun. The interior looks and feels good in a racy, functional way; you sit low, and the two tiny back seats are more suitable for chattels than people.

Above all, though, it's the purity and simplicity of this car's character that really appeals, and the huge entertainment it offers while also managing to be quiet enough, and supple enough over bumps, to be usable every day. This is how a sports coupé should be. I want one, badly.

.....wait... what? so its got almost prius like economy...
but.....
rwd, limited slip ,best EPS feel steering, ring framed, 200hp 2.0 L, 2700 lbs, awesome suspension, one of the lowest CoG known to production cars....

and its not a miata hybrid and it has 4 seats...

EDIT.... ohh yeah and its cheap?... im still confused....

42uk mpg is about 30 us mpg

One imperial gallon is approximately equal to 1.201 U.S. gallons.

ok sorry but still that's 35 mpg average.... that's still a lot in today's standards :D

42 imperial mpgs + magic = 35 us mpgs

maybe 42 highway 32 city :DDDD i can only hope

miata 01-08-2012 02:57 AM

It converts to 35 mpg (USA) Yes. I love it! Very impressed!!

ayau 01-08-2012 02:58 AM

Those numbers are impressive considering what my Honda Fit gets.

Spaceywilly 01-08-2012 02:59 AM

The test cycle is also not the same, but yeah that is not bad. It's not surprising though since it's 2.0L NA 4 cylinder with DI, light weight, designed for low drag, and premium fuel. I bet it will get great mileage in real life, I'm usually able to beat EPA by a few MPGs. 40mpg doesn't seem out of the question tbh if you do a whole tank on the highway and stay below 60. Realistically I expect it be low 30s though in normal driving.

for most of us, this will be very spirited driving :D

MiguelAE86 01-08-2012 03:21 AM

So this car gets better MPG than my friends accord, looks better, drives better, steers better, does about everything else better, and its a REAL car with an affordable price tag? I'm so glad I religiously waited 4-5 years for this car. Seriously, I'm proud of myself lol.

serialk11r 01-08-2012 03:40 AM

Test cycles are different yea, but how about we look at it like this: the car is "under 160g/km". The Lotus Elise 1.6 with the Toyota 1ZR-FAE engine is rated at 149g/km in the UK (is that same as EU test cycle?). The Lotus weighs about 700-800 pounds less, and has approximately the same drag. The Lotus likely uses a similar gearbox, with similar revs. The Lotus has only 80% of the displacement, and Valvematic cuts part load pumping losses to 0.

Meanwhile the FRS has a throttle plate, and higher displacement, so on paper it looks like it will need to work much harder on the highway. But the fuel consumption rating is only barely higher than the Lotus! 50% more power, 40% more mass, 25% more torque, less advanced valvetrain, but <10% more fuel usage? That's crazy. Spray guided direct injection seems like pretty potent stuff. Now imagine they swapped in a Valvematic system...better than a Prius? :O

With some hypermiling its possible! lol

All it takes is some resistance in driving like a racecar driver on the road.

soo... your on topic but off topic... yes its cool 50mpgs would be possible with d4-s in the 1.6 valvematic 1ZR-FAE in the new elise...

and on another note, adding valvematic to the FA20 would also be another world of tuning nightmares to add onto the d4-s no one really knows about either.... 42 mpgs average would be possible with such a set up but maybe it will be left for the latter years of the ft86 but right now im happy with a 35mpg average its about 4 mpgs better then the closest competitor... and the closest competitor, well its nowhere near the checklist the ft86 completes for me... there are too many rights for wrongs to start popping up to change my mind, i personally wouldnt have cared about a 25mpg highway estimate if it was aggressivly tuned...

35 us mpg average just means 2 things to me
1 gas stations will be less common than my current car = more time driving
2 the potential for power to be unlocked because of how conservative the tune is..

serialk11r 01-08-2012 04:37 AM

@ above
I guess you could say that I was sorta off topic. But this direct injection system appears to be rather amazing, if it improves so much over port injection that it can compensate for pumping losses, greater frictional loss, and greater power requirement. Might be some good tuning potential.

carbonBLUE 01-08-2012 04:51 AM

i dont mind off topic if it does incorporate the current topic and brings up a relevant issue/possible improvement that hasn't been brought up before, i could see the possibility of valvematic being introduced to the fa20, which bring up a question...

sorry for more off topicness

what is the fa20 using for valve timing/spark/fuel injection?

is d4-s a stand alone system that has its own timing seperate from vvt-i ,valvematic, avcs???

carbonBLUE 01-08-2012 05:02 AM

either way... another way to look at it...

how many brands improve the average fleet mpgs with a new sports car... especially since toyota is already known for having one of the best

serialk11r 01-08-2012 05:43 AM

FA20 appears to have cam phasing, no variable lift of any sort, as the head does not appear to have the space to accommodate the extra rocker/rollers/followers/whatever which all variable lift systems have. Sadly since boxer engines are so wide, I'm guessing variable lift won't make it for space reasons, unless they're willing to really change some stuff around. Valvematic doesn't provide a performance benefit in itself, but the better part load efficiency could give some emissions/efficiency headroom for larger cams for max power.

D4-S acts independently (as does any fuel injection) although timing is optimized according to the other parameters, if that's what you mean. I suppose D4-S + Valvematic (which needs to go with variable cam phasing to advance the cam when duration is shorter) makes tuning a bit difficult since lift dictates duration dictates load, and you would need to figure out direct injector timing not only at different speed but at different load as well.

Anyways, there's no reason a sports car should necessarily get worse mpg, just that up till recently engines have not been advanced enough to preserve fuel economy while offering high performance. D4-S seems pretty remarkable in that it can significantly improve combustion at low rpm even with a fixed profile cam that makes max torque at 6600 :O (besides the fuel economy/emissions benefits)

And I apologize that fuel economy appears in like 90% of my posts, I just like analyzing the thermodynamics a lot :P

In layman's terms: Not many $25K sports cars have direct fuel injection :burnrubber:

Another review that says it will be released in June.... (8/6?)

miata 01-08-2012 11:19 AM

June and spring. Officially June 21st is the beginning of summer so it will be sometime before then.

Guff 01-08-2012 11:42 AM

For some reason, 8/6 (June 8th 2012) sounds like the day...

I want it earlier, but that date is pretty darn cool!

I wouldn't mind 8/6 either even if it was August 6th.

That would be so awesome

Levi 01-08-2012 01:08 PM

I think I won't have any problem with consuption. My Alfa is new and I pay I need 10 liters to drive 100 km. I am sure the BRZ will be better and yet more powerful.

well if they drop it on june 20th (my b-day) ill be a happy mother fucker, i plan on buynig the car in cash then driving to vegas for the break in then blow some more money cause i can...

DRACHENV6 01-08-2012 11:41 PM

wow... 35mpg?! If true, this car would be good enough to be a daily driver for many folks. It would compare nicely with the corolla, and give other car manufacturers a reason to panic.

comparison:
2011 corolla 5spd - 2734 lbs 28/35mpg
2012 scion frs 6spd - 2700(?) lbs ??/35mpg


Those are crazy numbers. If everything they say is true, than toyota was justified in adding D4-S tech and subaru benefited as much as toyota, if not more from the collaboration.

i hope its 35 average between city and highway :D itll make the corolla look like a gas guzzler lol

Except there are a lot of sporty cars with direct injection in the $25k range. Just off the top of my head:

VW GTI/GLI
V6 Camaro
Colbalt SS
Mazdaspeed 3
New Genesis Coupe?

yeah but its not direct AND port injection

nobody who has a DI car likes the carbon build up problems :D
