Vs Battle of the supercars: Lexus LFA vs Audi R8 V10 Results

[330CIZHP]

Some stats for results:

Standing mile:

LFA: 30.58 secs@167 mph (Foust admits to dropping the ball and screwing up the launch big time. Used neutral dropped only, but reeled R8 V10 back easily like a freight train).
R8: 30.64@ 166.1 mph (r-tronic launch control)

Win: :LFA

Top speed:

LFA: 184.1 mph (Same as SportAuto. Too much handling downforce due to spoiler not retracting cost atleast 6-8 mph)
R8 V10: 185 mph

Win: R8

0 - 100 - 0 mph

LFA: 1168 ft@ 14.4 secs (LFA smoked off the line 3 - 4 car lengths lead with perfect launch. Tanner claims he was using LFA launch control system. See video)
R8 V10: 1167 ft @ 13.8 secs (r-tronic launch control)

Win: R8 V10

Road Course (Short 1 mile or 1609.3 meters course with 4 turns)

LFA: 44.8 secs
R8 V10: 45.9 secs
(Tanner again slept off the line. Still at the end LFA won by about 9 - 10 car lengths going at about 114 mph at the finish line. Lexus LFA was simply invincible here pulling in the corners from the outer edges and even harder on the straights. See video for finish)

Overall winner: Presenter gave the win to LFA/Tanner primarily over the huge win in the Road course.

Behind the scenes showing how LFA's ceramic brakes versus R8 V10 steel brakes since they faded very fast after the very first run.

Watch LFA using launch control with consistent traction equal to AWD Audi off the line and immediately pulling before 60 mph:

00.06 second advantage after 1609 metres is not a big difference if you ask me - with 35-more-hp.

Top speed:

LFA: 184.1 mph (Same as SportAuto. Too much handling downforce due to spoiler not retracting cost atleast 6-8 mph)
R8 V10: 185 mph

Win: R8

If I'm right, they did not managed topspeed, only 0-300 km/h time.

And lighter weight as well, I guess. You need to watch the video to really see how fast LFA was reeling it back in. The 0 - 100 mph video gives you a good idea since it is already 3 - 4 car lengths by that speed.

I mentioned in my comment that Tanner admitedly messed up the launch and got off the line a few tenths after and about 5 - 6 cars behind the R8 V10 using neutral drop (not launch control for this one), but it reeled it back in and passed before the 1-mile marker and was about 1 car length ahead at the finish line.

I will try and take some pictures from my DVR of the off the line distance at launch time that will illustrate this.

6/10th of a second translates to about 8 - 9 car lengths atleast on equal start in a 1-mile race at that kind of speed approaching 170 mph.

All of the launches you see in the 0 - 100 - 0 mph test video are using launch control system in LFA hence the perfect timing and traction.

00.06 second advantage after 1609 metres is not a big difference if you ask me - with 35-more-hp.

If I'm right, they did not managed topspeed, only 0-300 km/h time.

They were measuring top speed only for the runway space they had before a finish line therefore, it was "only" 184 - 185 mph, which is 295 km/h. Foust complained about the drag by the spoiler resulting in loss of acceleration by atleast 6 - 8 mph.

Not a big difference but the LFA had to overcome the R8's AWD grip weight distribution (it gained ~4 carlengths on the launch) plus the aero drag at high speeds due to the LFA's extended rear wing.

Actually no. Because when a car's doing 167 mph (269 km/h or 75 metres/sec) 0,06 second means 4,5 metres. Which is one R8's or LFA's length.

The R8 crossed the line 0,06 s after the LFA. And in that time it did 4,5 metres (est.).

Yes, my mistake. 6/100th and not 6/10th. Yes, it was about one car length lead at the end. You are right.

There were about 3/10 - 5/10th wasted for the LFA sitting at the start line not moving as in "Battle of the supercar" the video VBOX starts counting after the hands drop where the R8 V10 left with perfect timing.

The "freight train" comment was actually Paul Tracy's comment who saw the LFA reeling the R8 V10 close very fast in his rearview mirror.

Not a big difference but the LFA had to overcome the R8's AWD grip weight distribution (it gained ~4 carlengths on the launch) plus the aero drag at high speeds due to the LFA's extended rear wing.

If you see Foust's comment afterwards, you will see he clearly admits he dropped the ball on the launch as he did not even move. Plus the "neutral dropping" method on LFA is very flawed resulting in too much wheelspin.

The launch control seems to work perfectly here, which he discovered later on before the 0 - 100 - 0 mph test. You can see the multiple launches he is doing in the 0 - 100 - 0 mph test and LFA leaves just as quick as the R8 V10 off the line and then pulling away.

And the weight advantage it also has. But again here is another tester having serious problem getting the LFA off the line, and these guys are generally better drivers than most owners.

As for the difference at the end of the lap, all things considered like weight advantage, power advantage and price difference, I think the R8 put up a very good fight.

I would love to own either.

I agree R8 V10 is right up there with all the supercars, no doubt.

There were no issues with launching. It is just that Tanner did not know about launch control until half of the tests were done.

He used the neutral dropping technique in the standing mile test, which is very flawed since the gear is not pre-selected, but dropped from neutral to first resulting in a lag and does not control wheelspin plus his reaction issue (which he states as dropping the ball). LFA lost 3/10 - 5/10th sitting off the line because of that. They should have re-done the test with the launch control system and LFA would have easily left evenly.

He did not figure out the launch control system until the 0 - 100 - 0 mph test came along (he states in the video that he just found out there is a launch control and they showed a few test runs of LFA launching without any wheel spin)

Then LFA was launching as hard as the R8 V10 and then pulling away. You can see in this video where they did 3 runs and LFA got perfect launches everytime and pulling away by 3 - 4 car lengths by 100 mph. LFA atleast now seems to have a fantastic launch control system:

Just got a chance to to watch the show and I'm glad Tanner chose the LFA, I don't know why I can't stand Paul .

The standing mile should've been redone, even though the LFA won. The 0-100-0 test is a different story once the LFA's ceramic brakes warm up (as it shows in the behind the scene video). The road course is where the LFA shined, even though Tanner screwed the launch, again.

Tanner said it was the second LFA in the US, does that mean it's a production version, not the prototypes we've seen in previous videos?

 

[330CIZHP]

Agreed.

The neutral dropping technique should never be used and most tests had to use it. Tanner did not find out about launch control till the 0 - 100 - 0 mph test was done.

Here is a picture of LFA when R8 V10 was hittng 66 mph and both cars were using launch control system

R8 V10 with AWD has a very quick 3.4 - 3.5 seconds 0 - 60 mph with r-tronic launch control so that makes the LFA quicker to 60 mph with launch control.
