The pre-race and first in-race report from Le Mans

The 2013, 90th anniversary edition of the 24 Hours of Le Mans has begun, tragedy marking the opening laps with the death of Allan Simonsen. We're at the track now as a guest of Audi and plan to stay through the evening, and even we haven't been able to find out what caused the accident - the only video is from just after the incident, and beyond the statement from ACO there's been no more news. The Aston Martin in the LM GTE Am class and its all-Danish drivers had taken pole in its class and was one of the favorites to win.
The pre-race report will come first, and even thought we can't spoil the race because we're only five hours into it at the time of writing, we'll put all of the news at the end in case you don't even want the updates.
Or you can go straight to the high-res galleries above.

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.

Petrolicious profiles the rare Italian Porschephile

If you're Italian, you love Ferrari. It's almost a national requirement. If not Ferrari, then Lamborghini, or if you're a bit contrarian, perhaps Alfa Romeo or Maserati. This common belief, though, flies in the face of Rosita Corato's devotion to a certain unique Porsche. Despite growing up around cars from Italy's most treasured automakers, Rosita's family of coachbuilders had a passion for Porsche. This love was fostered by her father, who made a living repairing Ferraris. Despite his work, he'd longed for a rear-engined German, finally picking up a 1959 356 Speedster that was in desperate need of restoration. Rosita describes it as "practically a heap of metal" before her masterful metalworking father got to work on it. While it was originally meant to be a racer, it could best be described today as a restomod, and Rosita still uses it regularly on rallies. The engine and brakes have been upgraded, while the ratios on the manual transmission have been tightened up for improved performance. To save weight – remember, Rosita's father wanted a racer – the doors and hood were replaced with aluminum units, while other aesthetic upgrades were made as well, such as moving the fuel access up onto the hood. Check out Rosita's gorgeous 356 Speedster in the very latest episode from the team at Petrolicious. Related Video:
