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.

BMW adds new entry-level 320i model, priced from $33,445*

Fans of the new BMW 3 Series here in the US have likely been waiting for one of two models to arrive: the new M3 or the diesel-powered 335d. Well... keep waiting just a little bit longer. Here at the Detroit Auto Show, BMW is showing off the new entry-level 320i that will join the 3 Series lineup this spring, and rather than bringing added performance or efficiency, this car is boasting affordability above all. The 320i has been on sale in other markets since the current-generation 3 Series was introduced, but it goes on sale in the US with a starting price of $33,445 (*)including $895 for destination, which is $3,405 less than the current starting price of BMW's well-liked sedan.
In other countries, the 320i uses either a 1.5- or a 2.0-liter inline-four (both turbocharged), and the US version of the car will be getting the latter engine producing 180 horsepower and 200 pound-feet of torque. For comparison, the current 328i, which uses this same engine, produces 240 hp and 255 lb-ft of torque. As expected, performance of the 320i will suffer with BMW estimating a 0-60 mile-per-hour time of 7.1 seconds, but it still has the same 130 mph top speed as the 328i. Oddly enough, despite the lower output, BMW's expected fuel economy for the 320i equipped with rear-wheel-drive and the eight-speed automatic transmission actually matches that of the current 328i with 23 miles per gallon city and 33 mpg highway, and those numbers are actually lower than the 328i with the manual gearbox.
It sounds like most of the usual 3 Series options will be available on the budget-minded 320i, including the choice of xDrive all-wheel drive, BMW Assist and numerous packages including a Sport pack and Premium pack. For a lot more information on the 320i, most of it general information on the F30 3 Series, scroll down for BMW's press release.

Dinan S3-R BMW 1M Coupe

I nearly shed tears a few years ago upon learning that BMW was only planning to produce a very limited quantity of its then-new 2011 1 Series M Coupe. In simplest terms, the two-door was a 1 Series fitted with a modified version of the automaker's twin-turbocharged 3.0-liter inline-six, and the running gear (gearbox, driveshaft, axles) from contemporary M3 models. It was also a return to form for the brand. Aggressively short and stubby in stature but packing telltale flared wheel arches that hinted at its potential, the four-seater was a spiritual successor to the original (and much loved) E30 M3 from decades earlier.
After spending a day with the original high-performance 1 at New York's Monticello Motor Club, I declared, "The little coupe with the big flares is old-school retro cool and deliciously fun to drive ... the new BMW 1 Series M Coupe doesn't target boy-racers, it targets enthusiasts." Yet sadly - and despite strong demand - BMW limited the model's production to just one year. All told, only 740 units made it to the States, and each was gobbled up at a starting price of $46,135, a price tag history will show to be a bargain.
Since I had little hope of even driving one again, I deliberately pushed all memories of BMW's 1 Series M Coupe from my mind - until my phone rang recently. On the other end was a representative from Dinan Engineering who wanted to know if I would be interested in driving the company's new S3-R BMW 1M. A quick Google search revealed it to be a heavily modified version of the discontinued 1 Series M Coupe. As if they needed an answer...
