Porsche 918 Spyder roars electric through London

The Porsche 918 Spyder can be an object of lust for anyone who appreciates the finer things in the automotive world, but for us greenies with penchant for speed, the car is an icon. This gorgeous, all-wheel-drive plug-in hybrid offers 887 horsepower and 940 pound-feet of torque, can do 0-60 in just 2.5 seconds and is capable of 214 miles per hour. It lapped the Nurburgring in a record 6:57. Still, it is capable of near-silent, relaxed cruising through one of Europe's busiest cities. In a new video from Porsche, chief driving instructor Gordon Robertson takes the 918 to London and does just that. While driving in E-Power mode, he describes some of the things that make the car special, as well as how the technology has developed through the 911 GT3 R Hybrid and the 919 LMP1 car to eventually be passed onto the Panamera S E-Hybrid. If you're interested, you can learn more about the car in our own drive review, here. It's great to see, for the first time, the 918 Spyder driving alongside London's black cabs and double-decker buses. The rubbernecking from pedestrians is noticeable and completely understandable. I'm sure we'd all love to see this car come silently sneaking down our own city streets, but until Porsche makes that happen, you'll just have to enjoy the video below.

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.

Porsche picks Maria Sharapova as brand ambassador

Russian-born tennis superstar Maria Sharapova has just inked a three-year deal with Porsche to be its brand ambassador, a position that will put her on a global campaign for the German automaker. The 26-year-old athlete isn't new to the role - she previously signed a similar three-year deal with Land Rover in 2006.
"Maria Sharapova is an exceptional athlete. She combines top performance in her sports with elegance and power. These are precisely the qualities that are embroiled in our sports cars," explained Matthias Mueller, CEO of Porsche AG, during the announcement. "Her profile and charisma are an ideal fit for Porsche. She is also highly respected around the world and enjoys an outstanding reputation," he added.
Some consider Porsche's choice of a female tennis player as its ambassador interesting, if not surprising. The automaker has traditionally marketed its vehicles with a masculine edge - Sharapova and the sport of tennis position the brand in a different light - likely an intentional decision. Do you think Porsche's choice was a good one? If not, who would you choose as its global ambassador?
