LFA [Official] Lexus LF-A Supercar (Production Version)

[Levi68]

Thanks. Awesome pics, cars and festival. Actually my favorite car festival as there are mainly sportscars.
Now playing a childs game, if I was to pick one car from all those at the festival, and we all know how one is better than the other, my pic would still always be the LFA without a doubt.

Yeah, LFA Nurburgring Edition is my most favorite car as well. More so, than the standard LFA since it does not really give up on anything, but adds more.

You might wish to watch again the vid of the LFA NE @ Goodwood 2011. Just epic.

I think I missed an event a few weeks ago at the track that is 15 km from my home. There was an LFA and some GT86.

Was that in Italy??

I saw the passenger turning down the shift speed two notches probably because the shift shocks were getting to him. LOL

Regarding Goodwood, there will be new videos from 2012 ride for the winners soon. In the meanwhile, the one you posted has a newbie driving it. This one is better with Akira Iida in 2011 driving Nurburgring edition at Goodwood

No, that is in France. It must have been some enthusiasts from Swiss. There are more swiss than german or french, that is why trackdays are very expensive, and the track belongs to the owner of the Ferrari/Maserati and Lamborghini dealer.

It is a nice track with many curves that you can take in drift if you wish and a long straight line for high-speed.




I like the roll-cage of the LFA NE, it is nearly a full roll-cage unlike all other track oriented sport cars like the 911 GT3 RS, the M3 GTS, C 63 AMG BS and Mégane RS R26 whcih have a half roll-cage.

Goodwood Festival of Speed

After seeing this pic I'm now tottally certain that this shade of blue is the best coulour on the LFA.

 

[NarutoRamen]

Damn. Those are some gorgeous pictures. I know this is the LF-A thread...but damn, that CLK-GTR and McLaren F1-GTR

 

[martinbo]

Not an LFA but this deserves a repost in any thread!

Whimper...

 

[hoffmeister_fan]

yeah, I'm a well-documented LFA-phile, but between the CLK-GTR and the Macca, one can't help get bit of a chub from them. They both take me back when I used to "drive" them on NFS II and III back in the day.

Damn, I just feel old now.

A Porsche 997.2 GT3 RS chasing down a LFA in what looks like Manilla.

I know weaving through traffic is not smart. At 3:40 the LFA pulls away hard and comfortably leaves the GT3 RS behind

LFA NE 'AD-B'

Doesn't have the exhaust set-up like the AD-A. In fact, it looks like your run-of-the-mill NE LFA.

^^^

This could be another version of the LFA in the works where the changes are primarily under the skin. The 'AD-B' must mean something.

 

[Levi68]

There are two prototypes. It is here where were spied the Toyota GT86 and Subaru BRZ while testing they have the red number plates, so factory cars. I wonder why when now that the LFA is almost soldout, and the last clients are waiting for delivery, Lexus again test the LFA. So hard to believe Lexus is continuing with its sportscars while BMW is at its FWD, three cylinder eco cars and other vans, busses and SUVS. Oh, BMW has such a bad image in my eyes, I almost forgot they teased us with the coming M4.

The LFA NE reached max 282 km/h and finished its lap before 7:30 min. This car has so much potential. If it had DCT and more torque (?), but otherwise better acceleration it could be alot faster. Maybe LFA II must be a Hybrid. If they manage to bring weight even lower they can add 150 PS electric power it would rival the 918 Spyder, F70 and P12.

It was with the additional weight of a passenger and all that downforce.

It reached 289 km/h with Akira Iida going solo at Dottinger Hoe uphill and 298 km/h going downhill. Talking about low end torque is a moot point in the case of LFA. It is a very high-revving engine built on lightness, response, linear band and lots of top end power. On the race track, it uses high rpm torque and gearing to be very fast and powering out of the corners. So if it had say, 650 HP then everything else would be proportion, but it makes 571 HP from a very small, lightweight V10. One cannot have both ways.

I was not talking about low-end torque, especially because I have never seen such a flat turbo like torque curve on any NA engine. It is just that max torque is of 480 Nm, (100 Nm/l), whereas the 458 Italia, also a high-revving engine with redline at 9K rpm, makes 540 Nm (120 Nm/l). I think if the V10 got DI, it would be able to make at least 500 Nm (always flat torque curve) and 600 PS and even more if redline was lifted to 10K or more. Remember then engine is capable to rev up to 12K. One thing not to be forgotten is that the V10 is maybe one of the most reliable supercar engines. I Lexus would build the engines to a reliabilty level of Ferrari for intance, I am sure this V10 would make stratospheric numbers.


Other than all the downforce, what other prameters make that the LFA is not that fast from 200 to above 300 km/h ?

 

[330CIZHP]

Mclaren is turbocharged. Completely apples to oranges with N/A. More revs, but less peak torque. I am sure you know the pros and cons of each.

You are looking at only peak torque, which is only one point on the graph.

As a matter of fact, I remember having this argument with someone else when I posted dyno comparisons. The LFA engine actually produces a more flatter torque curve than that of the 458 Italia especially in the higher revs. Lexus was very proud of the fact that it makes over 90% of its torque throughout the whole rev range. It is also evident in the telemetry speedo where the acceleration rate is consistent and never falls off.

It is just that in the midrange, the 458 Italia engine has a torque spike between 4500 - 5500 rpm, which falls back down when it hits close to 6000 rpm.

The engine was built for reliability so DI in high revving engine is known to be highly unreliable and causes carbon build up (check RS4), but LFA does have 10 individual throttle bodies, which is the reason why it responds so much more quickly.

Since you are asking about acceleration, other than mysterious and unexplicable issues with a few poor 0-60 mph test numbers, LFA seems to be top notch in acceleration everywhere else (for example, 100 - 200 km/h consistently in only 7.3 - 7.5 seconds, 100 km/h - 260 km/h in 16.5 seconds etc.)
