2014 BMW 4 Series drops its top, priced from $48,750*

BMW will debut its new 2014 4 Series Convertible at the Los Angeles Auto Show in November, and after seeing plenty of spy shots and, most recently, some leaked images, we now have all the official details. To no one's surprise, the 4 Series convertible is, essentially, a topless version of BMW's new-for-2014 4 Series coupe, and will be offered in the United States in the same 428i and 435i guises.
On the base end, that means the 428i Convertible arrives with the company's 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and available with either rear- or all-wheel drive. BMW says the 428i will sprint to 60 miles per hour in a respectable 6.2 seconds. For folks in need of more thrust, BMW will happily sell you a 435i Convertible, available only with rear-wheel drive, powered by a 3.0-liter, twin-turbocharged inline-six that produces 300 hp and 300 lb-ft of twist. Hitting 60 mph in the 435i will take roughly five and a half seconds with the standard eight-speed auto. Curiously, BMW did not mention anything about a six-speed manual transmission for either model, so looks like this droptop might be an auto-only affair. We've contacted BMW for confirmation, so we'll keep you posted.
Like the 3 Series Convertible it replaces, the 4 Series uses a three-piece folding hardtop configuration, and BMW says that added sound deadening reduces audible wind noise by about two decibels. Folding the automatic roof takes just 20 seconds, and can be done at speeds up to roughly 11 mph. For chilly, top-down driving (something we're big fans of), there are now three-temperature neck warmers for the front seats - just like what Mercedes-Benz offers with its AirScarf system.

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.

These are the top luxury cars bought by people entering the segment for the first time

Let's say you just got a big promotion at work or the kids are moving out of the house, and you finally have some extra money. You decide to blow it all at once and treat yourself by upgrading your ride. Naturally, you look to a luxury automaker. What do you choose?
Models like the Audi A3 and Mercedes-Benz CLA-Class may be tailor-made to introduce buyers to the premium segment, but a new study finds that they don't garner the highest rates of non-luxury customer conquests. It turns out that a Volvo leads among folks moving up to a premium brand, and it isn't even one that's made anymore, at that.
A recent study by Polk and IHS Automotive looked at what models had the highest rates of buyers upgrading from a non-luxury segment. The information comes from its new vehicle registration data through April 2014. All ten top models boasted conquest rates of over 50 percent, but the Volvo C70 led the field with 68.01 percent of its customers coming from non-premium brands.
