Porsche 991 vs. 930 Flatnose in 911 Turbo convertible faceoff

The Porsche 911 Turbo has a legacy of being a tough car to drive. With a ton of power set right over the rear wheels, its reputation is to lose control as soon as the driver stops concentrating. However, this isn't quite so true anymore. The modern ones are tamed through technology with things like hydraulically controlled engine mounts, not to mention all-wheel drive. In its latest video, Autocar tries to decide whether 25 years of progress really makes the turbo a better vehicle.
It's summer, so what better version to compare than the 911 Turbo Cabriolet? In one corner, Autocar has the latest and greatest 2014 version pumping out 513 horsepower and 486 pound-feet of torque with a seven-speed dual-clutch gearbox. Its challenger is a 1989 911 flatnose convertible sporting 326 hp and 347 lb-ft of torque. It's a truly rare car in the UK with only eight of them remaining on the roads in that region.
Granted, this test isn't so much a battle as it is a comparison. There's no question that the modern 911 would beat the classic in practically every objective category. What the video aims to find out is whether the flatnose is better in subjective measurements like its "feel." Scroll down to watch these two droptop Porsches square off.

Conquest and controversy conclude the 2014 Rolex 24 at Daytona [spoilers]

If you don't wish to know who won the 2014 Rolex 24 at Daytona, you should avert your eyes right now. We'll even give you a double-space to skedaddle...
For those of you still with us, the first race in the United SportsCar Championship (USCC) is done, but the discussions about it certainly won't end for a while. Daytona Prototypes claimed the first four overall places, the top spot taken by the No. 5 Action Express Coyote-Chevrolet Corvette DP driven by Joao Barbosa, Christian Fittipaldi, Sebastien Bourdain and Burt Friselle. The 16th and final caution of the race bunched the field up for an eight-minute sprint to the flag, so the first place getter finished just 1.4 seconds ahead of the No. 10 Wayne Taylor Racing Dallara-Chevrolet Corvette DP driven by Max Angelelli. Third place went to Brian Friselle in the No. 9 Action Express Chevrolet Corvette DP, 20 seconds down. Chevrolet power hasn't taken the overall win since 2003, eleven years later it scores a one-two-three-four. The No. 6 Muscle Milk/Pickett Racing ORECA-Nissan 03 scored fifth place, the top LMP2 finisher.
The Prototype Challenge class win went to the No. 54 CORE Autosport team of Colin Braun, Jon Bennett, Mark Wilkins and James Gue.

Porsche 918 Spyder with Weissach package does 0-62 mph in 2.6 seconds

Porsche marketers are having a field day with the 918 Spyder after some last-minute tuning improved the car's performance. They now say that it's so fast it's already beaten itself. Let us explain: Using a Weissach package-equipped 918 as an example (which reduces the plug-in hybrid supercar's weight through the deletion of some interior items, more generous use of carbon fiber and magnesium wheels), the car's previous official 0-62 miles-per-hour time of 2.8 seconds has been cut to 2.6. Additionally, 0-124 mph takes 7.2 seconds and 0-186 mph is dispatched in 19.9 seconds, times that were reduced by half a second and 2.1 seconds, respectively.
In all-electric mode, a non-Weissach pack 918 does 0-62 mph in 6.2 seconds (with the package, 6.1 seconds), down from 6.9 seconds. Efficiency is also improved thanks to the final tuning. The New European Driving Cycle (NEDC) rating of a Weissach pack-equipped car equates to 94 miles per gallon, up three mpg compared to before. That's pretty good for a car with 887 horsepower!
