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.

Translogic 182: CXC Motion Pro II Racing Simulator

Translogic gets some seat time in the CXC Motion Pro II to test if the high fidelity racing simulator can impact our host's real-life track times. Host Jonathon Buckley hits the track at Auto Club Speedway of California in a 2015 BMW M4 to put down a baseline lap time before his virtual training session in the Motion Pro II. After learning the lines of the track in a simulated setting, Jonathon returns to the track to put his skills to the test. "We designed it, originally, as a professional training tool for race car drivers," says CXC Simulation's founder and president Chris Considine. "Make it authentic. Make it real." The Motion Pro II boasts "thousands of cars and track models," ranging from street cars, to rally and off-road vehicles. Will this hyper realistic racing simulator help Jonathon improve his lap time?

BMW unleases new M4 as MotoGP safety car

BMW has some considerable racing prowess to crow about, and draws on those credentials to create models like the new M4. But it's not about to rest on the laurels it's won at the end of innumerable races past and present. Mere months after the release of its latest performance coupe, BMW has already revealed a new M4 touring car for the DTM series, and has now unveiled its new M4 safety car for the MotoGP motorcycle championship.
Revealed on the BMW M Facebook page and set to debut at the front of the grid at the season opener in Qatar a couple weeks from now, the new M4 safety car is just the latest in a long string of official vehicles it has provided to the MotoGP series. Previous examples have included everything from the 1M Coupe to the M6 and the X6 M.
Like its predecessors, the M4 safety car features emergency lighting, special equipment and of course BMW's trademark white livery with red, navy and light blue stripes that, in this arrangement, give the new Williams Martini Racing livery a run for its money. Logos promote the BMW M Performance Parts you can buy to bring your own Bimmer up to spec, which on this car isn't likely have changed much from stock.
