Race Recap: Rolex 24 at Daytona was fast and feisty

Let the record show that victory at the 2015 Rolex 24 at Daytona went to the No. 02 Chip Ganassi Racing with Felix Sabates Target/Ford EcoBoost Riley DP driven by Verizon IndyCar drivers Scott Dixon and Tony Kanaan and NASCAR drivers Jamie McMurray and Kyle Larson. The winner did 740 laps to cover 2,634.3 miles in 24 hours and 57.667 seconds. That's a statement to this year's pace in spite of 18 cautions, two more than last year: the Michael Shank Racing Ligier got pole with a time of 1:39.194, slower than last year's pole time of 1:38.270; however, the winning car last year only did 695 laps. The fight for top honors was shaved to a four-car battle over the first third of the event. The No. 02 Ganassi car took the lead on the first lap, swapping it well into the night with the No. 01 Ganassi car, the No. 10 Wayne Taylor Racing Corvette DP, and the defending champion No. 5 Action Express Corvette DP, all of them staying within about 20 seconds of one another. The Action Express car had a fuel connector come loose and lost three laps getting towed back to the pits to have it reattached, but was back in the lead 18 hours in. The No. 01 Ganassi car dropped out with recurring clutch problems 22 hours in, retiring not long after. A race-within-the-race is where the concluding action happened, a seven minute, 30-second dash from the end of the last caution to the checkered flag. During the penultimate pit stops with an hour to go, Dixon was in second place followed Jordan Taylor in the Wayne Taylor Racing DP into the pits but beat him out, taking the lead. The Action Express car was in third. In the last pit stops of the race, Dixon gained even more time, getting a four-second advantage over Taylor. Then a full-course caution came out twenty minutes before the finish when a Prototype Challenge car hit the wall and caught fire, bunching up the field. That closed the pits, but the Wayne Taylor Racing car had to pit during that yellow because of a miscalculation of driver time. No driver can be behind the wheel for more than four hours in a six-hour period but Jordan Taylor was going to go over, so he came in to swap out for brother Ricky. That cost the team any chance of second place, since they took an additional drive-through penalty for entering closed pits. When the track went green again, Sebastien Bourdais in the Action Express car stayed all over Dixon for the final five laps but couldn't get around him.

2016 Dodge Viper ACR is ready to take a bite out of the Corvette Z06 [w/video]

The Dodge Viper ACR is back, and as Fiat Chrysler Automobiles tells it, it's the most venomous breed ever born. Before you get too excited, the 8.4-liter V10 produces 645 horsepower; five more than the standard Viper and five less than the supercharged Chevrolet Corvette Z06. It's unclear why Dodge didn't extract more from the huge engine, although we somehow imagine that certain people in Maranello, Italy had a say in the matter. Instead of blessing the ACR variant with bunches of extra output, Dodge instead turned to an aggressive aerodynamics package that it claims delivers nearly a ton of downforce at the Viper's maximum speed of 177 miles per hour. The total aero package includes an adjustable, twin-element, carbon-fiber rear wing, carbon-fiber diffuser, an extendable front splitter, and dive planes. Those big louvers on the hood? Yeah, they're removable, too. The "race-tuned" suspension uses coil-over Bilstein shocks that offer ten different settings and up to three inches of height adjustment. Kumho Ecsta V720 tires were built specifically for the Viper ACR, and come in 355/30 in back and 295/25 in front, with 19-inch wheels at all four corners. Along with the aero improvements, Dodge is claiming the Viper can pull a race-car-like 1.5Gs in higher-speed turns. Carbon-ceramic brakes with six-piston calipers add the stopping power that's greater or equal to the ACR's cornering performance. Dodge was also keen to reduce weight, taking some rather dramatic measures in the effort. The stereo has just three speakers, while the electric function was removed from the seats. Even the carpet has been replaced with a "lightweight" alternative. Finally, Dodge is offering up the innovative 1 of 1 customization it pioneered with the Viper GT earlier this year. That means that not only can you get the fastest Viper ever built, but it'll be entirely your own when you take delivery.

Performance doesn't matter anymore, it's all about the feel

We've just had a week of supercars and high-end EVs revealed. Many of them boast outrageous performance specs. There were multiple vehicles with horsepower in the four-figure range, and not just sports cars, but SUVs with 0-60 mph times under 3.5 seconds. And it's not just a rarified set of supercar builders, comparatively small tuners are also building this stuff. Going fast is easy nowadays and getting easier. So what will distinguish the greats from the wannabes? It's all about how a car feels. This may seem obvious. "Of course it matters that a car should have good steering feel and a playful chassis!" you say. "Why are you being paid for this stuff?" But a lot of automakers have missed the memo. This past week I spent some time in a BMW M4 Competition convertible, and it's a perfect example of prioritizing performance over experience. It boggles my mind how a company can create such dead and disconnected steering; the weight never changes, there's no feel whatsoever. The chassis is inflappable, but to a fault, because it doesn't feel like anything you're doing is difficult or exciting. The car is astoundingly fast and capable, but it feels less like driving a car and more like tapping in a heading on the Enterprise-D. I also happened to drive something of comparable performance that was much more enjoyable: a Mercedes-AMG GT. It was a basic model with the Stealth Edition blackout package, and even though it had a twin-turbo V8 instead of a six-cylinder, it only made 20 more horsepower. The power wasn't the big differentiator, it was (say it with me) the feel. While not the best example, the steering builds resistance as you dial in lock, giving you a better idea of what's happening up front. Pulses and vibrations come back to you as you move over bumpy pavement in corners. The chassis isn't quite as buttoned down, either, providing a little bit of body roll that tells you you're pushing it. It's also easier to feel when the car is wanting to understeer or oversteer, and how your throttle and steering inputs are affecting it. The whole thing is much more involving, exciting and fun. 2021 Mercedes-AMG GT Stealth Edition View 8 Photos That's also to say nothing of the Merc's sounds. That V8 is maybe not the best sounding engine, but its urgent churn through the opened-up exhaust gets your heart racing. It also seems like it's vibrating the whole cabin, so you feel it as much as you hear it.
