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.

This 1966 BMW 1600 Neue Klasse lives on the backroads

Among early BMWs, the 2002 gets a lot of love for being a relatively accessible, great-handling little sports coupe. Jim Huff explains in the latest episode of Petrolicious why the slightly earlier BMW 1600 Neue Klasse sedan also offers a fantastic drive – especially with some choice modifications. Huff was a fan of 2002s until his wife gave him a vintage BMW sedan model car as a gift. That toy sparked his interest in the Bavarian automaker's earlier four-door models, and he had to have one to drive. He eventually tracked down his 1966 1600 and started on a project to convert it into a great vehicle for blasting over California's backroads. Huff's 1600 still features the original classic lines, but his now includes a larger 2.0-liter engine with Weber carbs, an upgraded suspension, and improved brakes. As a result of the tuning, the vintage BMW can hang with Huff's buddies in Alfa Romeos and Porsches on curvy roads. It sounds fantastic, too. Petrolicous interviews Huff, and he discusses a little about the history of these sedans. The real highlight is seeing and hearing his BMW in motion, though. Enjoy the ride with him in this video.

On Location in California with BMW and Mini

A mid-winter escape from frigid Michigan to drive a trio of new BMW and Mini products? It'd be a busy couple of days, but you can't argue with Southern California in February. The temperatures in LA, where we drove the Mini Cooper S Convertible, hovered in the mid-80s, and it was solidly in the 70s further north, at Monterey, where we drove the M2 and X4 M40i. The highlight of the trip was Mazda Raceway Laguna Seca, which is a rewarding track to drive in a street car. The M2 was a blast there. The canyon roads above Malibu in the Mini were a close second, but even the lazy drive down the PCH to Big Sur was a blast. More important is the California state of mind we were in when driving all three of these cars. I've spent a lot of time in this state, and it has a complicated relationship with the car – and there's also a huge difference in attitude between the greater Bay Area and Southern California. Ample sun and twisty roads clash with image-consciousness, eco-consciousness, and brutal urban gridlock, and each BMW dealt with that paradox admirably, in its own way. Take a quick jaunt to California with me and check out the locations and experiences that helped form our impressions of these vehicles: the 2016 BMW M2 First Drive, the 2016 Mini Cooper S Convertible First Drive, and the 2016 BMW X4 M40i Quick Spin.
