The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Ford Mustang outsold Audi TT and Porsche 911 in Germany

Despite being the antithesis of the cars Germany is known for, the new Ford Mustang was the best selling sports car in the land of schnitzel and beer last month by a whisker. The Mustang beat out the Audi TT by 780 units to 708, and it beat Germany's best known performance car, the Porsche 911, 780 to 752. That makes some sense, right? The Mustang has to be cheaper than those competitors, right? Not really. Both the EcoBoost and V8-powered Mustang have higher starting prices than the equivalent TT. The 2.3-liter, EcoBoost-powered Mustang starts at 38,000 euros (around $43,300 at today's rates), while the front-drive Audi TT starts at 35,950 euros (about $41,000). The V8-powered Mustang GT, meanwhile, starts at 43,000 euros (about $49,000), which is just 2,550 euros more than the Quattro-equipped TT. When 310 horsepower or 435 hp can be had for just a couple thousand more than 220 hp, it's easy to understand the Mustang's success. The 911, of course, is a lot more expensive than the Mustang. You can buy two Mustang GTs for the price of a single Carrera. But Ford also managed to beat out the Porsche's smaller siblings, the Boxster and Cayman twins, which sold a combined 642 vehicles. Again, the pony car is significantly cheaper, but that doesn't do much to lessen the impact of the Mustang's victory. If you're in Germany and are concerned about this American invasion, you shouldn't be (yet). The TT is Germany's best-selling sports car from January through March, with 2,299 to the Ford's 1,823. Porsche is breathing down the pony car's neck, too, with 1,811 units in 2016. It'll be interesting to see if Ford's successful March carries on into the rest of 2016. Related Video:
