BMW 2 Series Active Tourer is the world's first front-drive Bimmer [w/videos]

While BMW has been showing concepts for its Active Tourer for over a year, they never seemed entirely real. Why would BMW, a company that has built its image on sporty, rear-wheel drive sedans, move into the five-door, front-wheel-drive market? The answer is still not entirely clear, but the new BMW 2 Series Active Tourer is very real. It launches in Europe later this year and is rumored to come to the US in 2015.
To brand purists, a front-wheel drive BMW may seem anathema to everything the company has built, and the production Active Tourer has clearly been built to provide drivers with a luxurious but utilitarian package first and foremost. It is 170.9 inches long and rides on a 105.1-inch wheelbase, but despite its compact dimensions, its high roof allows for 16.53-cubic-feet of cargo space with the rear seats up or 53.33 cubic feet with them folded flat. Its general appearance is nearly identical to the previous concepts, except with a blunter nose and cleaner lines. The front end wears BMW's traditional dual circular headlights and naturally, while the profile incorporates the company's traditional Hofmeister kink into the greenhouse's rear pillar. The interior has been designed to be especially useful with a sliding rear seat, adjustable rear backrests, fold-flat backrests and optional features like an automatic tailgate and panoramic sunroof.
Unlike both previous concepts, none of the Active Tourer models at launch use hybrid power. For Europe, the hatchback is going on sale with three engine options. The basic version is the 218i Active Tourer with a 1.5-liter, turbocharged three-cylinder with 134 horsepower that we just previewed in the 2014 Mini Cooper - good enough for average fuel economy of 48 miles per gallon in the EU cycle when equipped with a six-speed manual. The next step up is the 225i Active Tourer with a 2.0-liter turbocharged four-cylinder that makes 228 hp and offers 39-mpg average fuel economy. Finally, there is the there is the 218d Active Tourer with its 148-hp, 2.0-liter turbodiesel and 57 mpg average fuel economy on the EU cycle. A six-speed manual is standard on all of them, but there is a six-speed automatic option for the 218i and eight-speed automatics available for the 225i and 218d. All-wheel drive will be available on future models.

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.

2015 BMW M3 Sedan, M4 Coupe are officially revealed [w/video]

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.
