Audi outlasts rivals to win 13th Le Mans title

As is so often the case, the 2014 Le Mans was a war of attrition, and Audi managed to prevail once again after all 24 hours had been recorded in the history books, with its Audi R18 E-Tron Quattro claiming first and second places, followed by Toyota in third. Drivers Marcel Fassler, Andre Lotterer and Benoit Treluyer inherited the lead in their No. 2 Audi after the No. 7 Toyota, driven by pole-sitter Kazuki Nakajima, was forced to retire with electrical problems in the 15th hour.
The No. 2 Audi led the race until it was forced to the pits to replace a turbocharger in the 17th hour, allowing the No. 1 Audi, driven by Lucas di Grassi, Marc Gene (who was a last-minute replacement for Loic Duval, who crashed hard during practice) and defending champion Tom Kristensen, led the race until the 21st hour, when it too had to pit with turbocharger issues. This gave the No. 20 Porsche of Timo Bernhard, Brendon Hartley, and Mark Webber the lead until it was forced off the track with gearbox problems, eventually finishing in 38th position.
In LMP2, the Jota Sport Zytek Z11SN-Nissan driven by Simon Dolan, Harry Tincknell and Oliver Turvey claimed victory, the first five LMP2 finishers all powered by Nissan. Down a level in GTE-Pro, No. 51 AF Corse Ferrari 458 Italia GT2 driven by Gianmaria Bruni, Toni Vilander and Giancarlo Fisichella finished one lap ahead of the leading Corvette Racing C7.R. And finally, the No. 95 Aston Martin Racing Vantage GTE driven by Kristian Poulsen, David HeinemeierHansson and Nicki Thiim won the GTE-Am race two laps ahead of a Proton Porsche 911 GT3 RSR.

Next Porsche Cayman and Boxster to be called 718?

Porsche has spent a few years sorting out its strategy away from the 911 and its crossovers, among the moving targets being the now-moribund Ferrari-fighting 960, the still-very-much-alive variant(s) coming with the next-generation Panamera, and what appears to be a puissant Cayman that could be called the GT4. Earlier this year there were rumors that a flat-four engine would join the Stuttgart maker's lineup, and that it could go into a roadster called the 718 that would undercut the current $51,400 price of the Boxster, and the Boxster would go upscale, leapfrogging the $52,600 price of the Cayman. Then Porsche turned out the lights on the 718 project, its R&D head telling Autocar, "We have a very good entry point to the range with the Boxster, and we see no reason to go below that." But Automobile reports that while the 718 roadster is dead, the 718 name will live: a la the 911, a new 718 range will encompass coupes and convertibles spanning a wide performance envelope. The suggestion is that the Boxster and Cayman names will be retired. According to Automobile, this will give Porsche a place to put its flat-four engine, into entry level models that – countering Porsche's earlier statement – "come in at a significantly lower price than" the present Boxster. Two displacements are expected, in three outputs: a 2.0-liter with 285 horsepower, a 2.5-liter with 360 hp and a turbocharged version with 400 hp. It's also been speculated that the engine could power an entry-level Macan. It's been reported before that Porsche wants to make use of the 718 name to promote its motorsport heritage, that model having carried Stirling Moss to victory among its many racing triumphs. If it happens, even though Automobile calls it part of "a slight perspective shift," we think it'll be a big shift for the two popular models, but it's not like we haven't had time to get ready. We're told the new moniker will be introduced in 2016 as a 2017 model. News Source: Automobile via World Car Fans Porsche Convertible Coupe porsche 718

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.
