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.

2016 BMW X1 takes a more mainstream approach [w/video]

I really like the outgoing X1, simply because it's still an 'old' BMW. I say 'old' because all of the 'new' BMWs don't really feel that great to me – they just aren't the driver's cars they used to be. But the X1 still uses the rear-wheel-drive 1 Series architecture, and I love the way it drives. As for this new X1, it looks to be a vastly improved product in many key areas, but I worry that it, too, will suffer from the same sort of dulling that every other BMW has received. So it goes. Nevertheless, the new X1 should appeal to a broader range of luxury crossover shoppers. It ditches the cool, tall wagon shape of the old model in favor of a more traditional CUV shape. Think small X5. There's far more technology inside and out, passengers will enjoy an increase in spaciousness, and the X1 is more efficient than before, as well. Only one engine will be available in the US – BMW's 2.0-liter, turbocharged, inline-four-cylinder with 228 horsepower and 258 pound-feet of torque. All-wheel drive is standard, as is an eight-speed automatic transmission. While I'm not sure if this X1 will be as entertaining to drive as the outgoing model, the new car's improvements will surely help sales. That's especially important as small, luxury CUVs are hotter than ever. See the new car for yourself, live from Frankfurt, in the gallery above. The All-New BMW X1: - Greatest interior roominess and versatility in its class - Highest power with reduced emissions - Commanding presence, robust proportions, dynamic lines - Innovative connectivity and groundbreaking BMW EfficientDynamics technology unparalleled in the segment Woodcliff Lake, N.J. – EMBARGO: June 2, 2015 – 6:00pm EDT/3:00pm PDT... Today, BMW announced the all-new BMW X1 Sports Activity Vehicle. In its second generation, the new MY 2016 BMW X1 builds on the success of its predecessor (61,974 sold in the US to date) by incorporating a roomier interior, greater efficiency and technology on the forefront of innovation. The second generation takes to the stage with a body design typical of a BMW Sports Activity Vehicle. The BMW X1 xDrive28i will be the exclusive model in the US at launch featuring a 2.0-liter TwinTurbo 4-cylinder engine from BMW's new family of modular engines with maximum output of 228 horsepower, making the all new BMW X1 the most powerful entry model in the segment. It will be mounted to an 8-speed Steptronic automatic transmission.

BMW reveals X4 M40i performance crossover

The first details and images of the new BMW X4 M40i leaked out Tuesday, and now the Bavarian automaker has released all of the information on its new performance crossover. The latest model in BMW's M Performance line offers an array of upgrades over the existing X4, and they start under the hood. That's where Munich fitted a new 3.0-liter turbocharged inline six based on the one found in the X4 xDrive35i (whose place this model takes at the top of the X4 lineup). The engine is tuned to deliver 355 horsepower and 343 pound-feet of torque. In addition to the twin-scroll turbocharger, the engine also boasts variable cams and valves, as well as a high-precision injection system. This translates to a 0-60 time of 4.7 seconds – a figure which BMW cites as "best-in-class." Power is channeled to all four corners through an eight-speed automatic transmission and a re-calibrated xDrive system that's biased to the rear wheels. Naturally the suspension has been upgraded as well, with increased camber, stiffer springs, reinforced stabilizers front and rear, and active dampers. The steering rack has also been retuned. You'll be able to tell the M40i model from lesser X4s by its enhanced appearance. Though the aero kit looks largely the same as the stock version, BMW has fitted the M Performance model with metallic accents, 19- (or available 20-) inch alloys wearing Michelin Pilot Super Sport rubber, and a variable sport exhaust. Inside, it's also upgraded with a unique steering wheel, shifter, sports seats, and specific badging. This adds up to a crossover that may not be a full-on M model, but promises up the performance quotient significantly over the rest of the X4 line. THE NEW BMW X4 M40i - World premiere of the new inline 6 cylinder TwinPower Turbo engine. - Intelligent BMW xDrive: four-wheel drive with rear-wheel-drive characteristics. - A sporty chassis specifically tuned to M Performance specifications. Woodcliff Lake, N.J.- September 30, 2015... Today, with the introduction of the new BMW X4 M40i, the successful BMW X4 has gained a new top model. In the Sports Activity Coupe segment (SAC), the BMW X4 M40i is setting new standards with enhanced driving dynamics and best-in-segment acceleration. The new BMW X4 M40i will be available at dealers starting February 2016. Design. The exterior of the new BMW X4 M40i makes it stand out as a clear member of the BMW M Performance family.
