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 is the BMW Z4 GTE that will wear the Roundel in ALMS

The Speedweeks at Daytona International Speedway are a month of racing and reveals, with the season's metal going for the flag at races like the Rolex 24 at Daytona and other cars being introduced to the public. In the latter category is the BMW Z4 GTE (click the image above to enlarge) joining the American Le Mans Series GT class this year with BMW Team RLL (Rahal, Letterman and Lanigan). This machine replaces the M3 GT that completed four years of service and won the class title in 2010 and 2011. Naturally, the team is tempering expectations for the Z4 GTE by repeating the fact that it sees this season as a development year.
BMW Team RLL drivers for its two cars will be Bill Auberlen and series rookie Maxime Martin in the No. 55, aided by Jörg Müller for the endurance races at Sebring and Road Atlanta. The No. 56 car gets Dirk Müller on a full-time basis, Joey Hand when he's not competing in the DTM series, and John Edwards when Hand isn't available. Uwe Alzen will help out with driving duties in the No. 56 at endurance races.

This Alpina C1 is a rare bit of BMW 3 Series history

Over its five decades in the business, German tuner-turned-automaker Alpina has established a long history of taking great BMWs and making them just a bit tastier, more luxurious, and well... faster. Of course, they haven't always been the land rockets of modern day, however that's not to say they were exactly tame. Back in the early 1980s, this was one of the cars to have—an Alpina C1 2.3. Based on the original E21 BMW 3-series, the C1 2.3 bridged the performance gap between the standard BMW 323i and Alpina's hard-charging B6 2.8. It summoned up a heady 170 horsepower and disposed of the 60 mph sprint in just seven and a half seconds. Not shabby at all. 33 years later, this '83 Alpina C1 is back up for sale , and it's still quite the head-turner. RELATED: Check Out the Hard-Charging 2016 Alpina B6 xDrive A look back at the C1's contemporary relatives show just how wide Alpina's performance gap had been. Introduced in 1977, the BMW 323i offered up 141 horsepower courtesy of BMW's famed M20 straight-six engine, a big performance improvement over the E21's previous four-cylinders. The Alpina B6 2.8 3-series on the other hand, introduced in 1978, blew its doors off thanks to the bigger 2.8-liter straight-six plucked from the BMW 528i, offering up 200 horsepower. All that, in an early 3-series. With that in mind, a middle-of-the-pack car made sense, so Alpina treated the 323i's straight-six to some of the B6 2.8's goodies, minus the former's Bosch fuel-injection system. Bilstein shocks were part of the diet too, along with oversized disc brakes, sleek alloy wheels, as well as the tell-tale Alpina front splitter, rear spoiler, and racy side-stripes. RELATED: The BMW Isetta is Coming Back, But as an Electric Vehicle! Inside, Alpina added a dose of luxury as well. One could order their C1 2.3 with the gorgeous optional Recaro seats with Alpina stripes, as well as a bespoke leather steering wheel, gear knob, and speedometer. Top speed? About 130 mph. Compared to regular E21 BMW 3-series cars, these are quite rare. How rare is a point of debate, however. Production estimates range from as few as 35 to as many as 400, depending on the source. Regardless, you certainly don't see them everyday, and if this one fits your fancy... it lives in Philadelphia, Pennsylvania. Related Video: This article originally appeared on Boldride.com.
