How Porsche got Patrick Dempsey into the driver's seat for Le Mans

How do you get to Carnegie Hall? Practice, practice, practice. Ask Patrick Dempsey and he'll likely tell you the same secret for landing a role on a hit TV show or, for that matter, driving a Porsche in the 24 Hours of Le Mans.
That's because, like McQueen and Newman, Dempsey has earned his place in that rarified field of actors who also race. He's competed in Baja and Grand-Am, co-owns an IndyCar team, and this year returned to Le Mans where he and his teammates Joe Foster and Patrick Long finished fourth in the GTE-Am class behind the wheel of their Porsche 911 RSR.
It's a grueling race, and the fluid transition between drivers behind the wheel is a key element to success. Check out the satirical video below to see how Dempsey and company got ready.

2013 Porsche 911 Carrera 4S

I don't care who you are; when a new Porsche 911 rolls up in your driveway, that's a pretty good day. This was my very first experience with Porsche's 991 911, and after having spent time with just about every tune and trim of the last car, I was hotly anticipating comparing and contrasting.
Somehow (I don't remember sending out any cash-filled, unmarked envelopes) I'd scored a week in the 911 Carrera 4S over a long holiday weekend, too. That meant that I'd get to A) log a ton of miles in one of the best cars in the world, B) get to show-off the Porsche to family and friends and C) tempt cops in three states to pull me over. Good thing I've got the Autoblog traffic lawyer on speed dial...
Driving Notes

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.
