Porsche's 959 is still poster-worthy after all these years

Today, we have the Porsche 918 Spyder. Before that, there was the Carrera GT. While both of those cars are dramatic departures from the traditional, rear-engine Porsche formula, they owe their very existence to another wild child of the iconic German brand - the 959.
Like so many of the great performance cars of yesteryear, the 959 was a homologation special, built just so Porsche could go racing in the clinically insane Group B rally series. Fewer than 400 959s hit the streets, but those that did were some of the most advanced cars of the 1980s. A rear-mounted, twin-turbocharged flat-six sent its power through a still-rare all-wheel-drive system, creating a race-inspired rocket that was, for a short time, the fastest production car on the planet.
Xcar has the story of the 959, from its inception to its conquest of the Paris-Dakar rally, which is interspersed with a drive of the legendary coupe. Scroll down for the full video.

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.

How the 2016 Porsche 911 Carrera S falls short of perfection

We know Harry Metcalfe loves a good Porsche 911. After all, he's shown off his personal 1989 Porsche 911 Turbo and 993 GT2 replica in previous videos. However, he can't seem to muster so much passion for the forced induction engine in the 2016 911 Carrera S. The chassis impresses him, but in Metcalfe's latest clip, he explains why he's not a huge fan of the new powerplant. Before any actual driving, Metcalfe takes a thorough walk around the new car where he goes to the unusual trouble of using a magnet to show which parts are steel and which are aluminum. Remember, though, this is a 911. So, this latest refreshed model, just like all previous remodels, isn't all that aesthetically different from the previous version. So, Metcalfe's real focus here is on how it drives. He comes away with mixed impressions. Metcalfe loves the 2016 911's handling, especially the directness from the rear-wheel steering, but he isn't in love with the new engine. At least with the seven-speed manual, he complains of turbo lag below 3,000 rpm. He also misses the direct throttle response from the previous naturally aspirated unit and doesn't think the turbocharged mill's fuel economy is very impressive. Take a ride with Metcalfe to get the full experience and intriguing take about the biggest change in more than a decade for the iconic 911.
