Evo sets up duel of Porsche 911s

What's better, rear-wheel drive or all-wheel drive? That question has occupied auto enthusiasts for years, and so far, we've not really had a solid answer one way or the other. Evo has opted to take another whack at this tough question by pairing a pair of Porsche 911s against each other for a track battle.
In one corner, we have the two-wheel-drive 911 Carrera S, complete with the lickity-split PDK transmission, a sports suspension and carbon-ceramic brakes. In the other corner, it's the all-wheel-drive 911 Carrera 4S in a much mellower spec, with a seven-speed manual, as well as standard brakes and suspension. While the results seem like they'd be a foregone conclusion, some very British weather is there to act as the great equalizer.
We've got the full video down below. Have a look, and let us know if you agree with Evo's results.

Studiotorino shows new Cayman-based Moncenisio sports car

While the recent bankruptcy of Bertone shows that it has become very difficult to be a coachbuilder today, it seems there is still a business case in creating unique bodies for premium vehicles. Case in point, Studiotorino a small, Italian coachbuilder that has been creating limited-edition cars since 2005. Its latest creation is the Moncenisio, which debuted as a prototype at the National Automobile Museum of Turin on March 21. It's named after the 1902 Susa-Moncenisio race in Italy, the first automotive hillclimb in the world.
The Moncenisio begins life as Porsche Cayman S, and each car will be built to order with a planned production run of 19 examples. The chassis, mechanicals and engine are all left untouched. The only thing that Studiotorino alters are the body panels and interior appointments. Prices start at at a heady 145,000 euros ($200,420 US), plus the cost of the donor vehicle.
Architect Daniele Gaglione penned the shape of the Moncenisio, taking inspiration from the 1963 Porsche 904. The sports coupes receive carbon fiber pieces that replace the front bumper, side panels and rear bumper. Studiotorino also covers the rear side windows with welded metal panels. The design is still clearly a Cayman, especially from the front, but the extended roof and support pillars create a new look from behind, which features a new exhaust treatment and rear spoiler. The interior receives leather upholstery on the engine compartment cover, the partition between the engine and seats, ceiling and A-pillars.

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.
