Is the skill of rev matching being lost to computers?
Fri, Oct 9 2015If 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 doesn't think autonomous cars fit brand
Mon, Feb 1 2016Porsche customers have no need to worry because the company has no intention of taking away driver control by introducing autonomous tech for its vehicles. "One wants to drive a Porsche by oneself," company CEO Oliver Blume told a German newspaper, Reuters reports. For the sports car maker, this is a sensible decision, as its owners are driving enthusiasts who desire an exciting experience behind the wheel. Blume also isn't a big fan of people using their phones in the car. "An iPhone belongs in your pocket, not on the road," he told the newspaper. While Blume doesn't like some cutting-edge automotive tech, he's no Luddite. The CEO eventually wants every Porsche to be available with a hybrid powertrain option, including the 911. A plug-in version of the famous sports coupe could be ready by 2018 and have a 31-mile EV range (presumably on the European cycle), according to Reuters. The evidence suggests that Porsche is very serious about electrifying the 911. A company exec admitted the automaker had PHEVs under discussion. Spy shots (above) already showed one testing that possibly had a charger on the passenger side rear fender. The 911 PHEV would also follow logically from Porsche's recent surge to electrify its models. The Panamera and Cayenne already offer plug-in versions, and the 918 Spyder proves the system can perform. Applying that battery knowledge to the 911 is a natural move, especially with the fully electric Mission E taking another technological step forward around 2020. Related Video:
Porsche revisits the 911's dirty side with rally history film
Fri, 03 Jan 2014It might not be a coincidence that there are rumors of Porsche revealing a safari version of the 911 at April's Beijing Motor Show, just as the Dakar Rally is about to begin. Adding fuel to the dusty desert fire is a just-released official video of Jeff Zwart driving the Porsche 953 that Jacky Ickx drove to victory in the 1984 edition of the race.
In the video, the seven-time Pikes Peak International Hill Climb winner talks about how he grew up with the 911; it wasn't only the car he learned to drive in, it was his choice of racecar no matter whether the course was tarmac or the dirty stuff.
You can decide for yourself if these recent events are mere coincidence while you enjoy the 953's exhaust note in the video below. If you've got the time to see the 953 during its race-conquering drive and find out what the ersatz Paris-Dakar Rally used to be, we've also included a broadcast of that 1984 race below as well. Fast-forward to 19:44 to see the Porsches cross the open dessert and 29:09 to watch one of them tackle the dunes.
