"The power from the Aston is awesome, but the downside is that 5th gear is too short and 6th is too tall. Also, its high-speed stability isn't good. The entire chassis became jittery over the bumps going into 3, making it the most nerve-racking car here today. On the other hand, the R8 is the most composed of the group. The suspension setup is ideal for the oval, allowing you to roll into the throttle with a lot of confidence. The only problem was its power and R tronic transmission; it wanted to keep downshifting to 5th when I wanted to stay in 6th," Yasukawa commented.
The finished in a solid 4th place. With all its unadulterated torque and downforce-producing bodywork, we expected the ACR to garner one of the top three slots, but the car's gear ratios proved to be its nemesis.
"This car is really fast, and it feels the most like a race car of the group, but its gear ratios are all wrong for the oval. You run out of revs in 4th, and 5th is too tall. And an oval isn't a place where you want to do a lot of shifting, so it was at a disadvantage. I would definitely like to go all-out in this thing with the right gear ratios," Yasukawa said.
It was practically a dead heat between the and , with only a hundredth of a second separating the two. The Lambo was faster on the straight, while the GT-R gained ground through the corners. Yasukawa admired both all-wheel-drive machines.
"The GT-R gets to speed really quickly, and the gear ratios are set up ideally for this oval. The car's front end feels a bit too stiff for this track, but once in the corner, it has a lot of grip. The main problem with the Nissan was that it vibrated a lot at over 150 mph. The Lambo, on the other hand, is really composed at high speed. The car gets a bit nervous when you brush the brakes and aim for the bottom of the turn, but once there, it's stable. And the sound is phenomenal," he commented.
Winning the day was the . It was the odds-on favorite coming into the test and did not disappoint. The car was fastest on the straight and through the corners, leaving no doubt about its superiority. Yasukawa was thoroughly impressed.
"The car has great grip in the corners and amazing power coming out of them. It has a comfortable neutral feel, which allowed me to get back on the throttle quicker than most anything else here. And the Porsche would have been faster if the suspension was a little softer. It's ideal for a road course, but here on the oval, it's pretty rough because the car is literally hopping over the bumps, and it was hard to pick a good driving line. That it was the fastest car here, and could have still gone faster, is incredible," he said.
Although no one in his right mind would attempt to drive any of these cars flat-out on an oval, running them on the Auto Club Speedway gave us a unique perspective to each car's high-speed characteristics. According to Yasukawa, the all-wheel-drive cars were definitely the most stable of the bunch, followed by the front-engine ones, but it was a rear-engine/rear-wheel-drive car that won the day.
