Alpina bringing new B4 Bi-Turbo Cabrio to Geneva

Interested in picking up a new BMW 4 Series with a turbo six? You've got options: you can get the 435i with 300 horsepower or spring for the M4 with 425 hp. But if it's the convertible model you want, we're afraid you'll be limited to the latter as the M division can't help you (at least not for the time being). But that's where Alpina comes in.
The aftermarket tuner closely associated with BMW offers the B4 Bi-Turbo (at least in Europe) with that same 3.0-liter twin-turbo inline-six massaged up to 410 horsepower that starts to pose a threat to the M4. What's more is that the Alpina's 442 pound-feet of torque eclipses the M4's 406 lb-ft, to say nothing of the 435i's 300.
Best of all, Alpina just confirmed via Facebook that it'll offer the B4 in convertible form, bringing the resulting BMW Alpina B4 Bi-Turbo Cabrio to the Geneva Motor Show. We'd expect the weight penalty to knock it slightly off the coupe's quoted 4.1-second 0-60 time, but not by much. If only BMW were to bring this one Stateside like it does with the B7 sedan.

BMW 4 Series Convertible basks in the sun

The BMW 4 Series Convertible will show its non-camouflaged face sometime later this year, but our spies recently caught this nearly naked prototype out getting some sun. As you'll recall, the droptop 4 Series replaces the 3 Series Convertible in the BMW range, and if our recent stint behind the wheel of the new 435i Coupe is anything to go on, this topless 4er should be quite a fun runabout for sun-drenched motoring.
To no one's surprise, the 4 Series Convertible shares all of its design with the 4 Series coupe, save, of course, the obvious roofectomy. Beyond that, the topless 2+2 will use the same engines and transmissions as the coupe, meaning it should arrive in the US in both 428i and 435i guises, powered by a 2.0-liter turbocharged inline-four and 3.0-liter turbocharged inline-six, respectively. Both six-speed manual and eight-speed automatic transmissions will be available.
The car spied this time around has the full M Sport visual treatment, with the revised (and better-looking) front fascia, larger 19-inch wheels, and attractive Melbourne Red paint. Interestingly, it appears this prototype has the standard xenon headlamp setup, rather than the full-LED option that's also available.

The 2016 BMW M2 is a steroid-addled M235i [UPDATE]

UPDATE: As it turns out, BMW mixed up the weight specs in the official press materials. We spoke to BMW for confirmation, and the manual M2 weighs 3,450 pounds, the DCT car weighs 3,505. We've updated the text to reflect this. If you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. When we first got behind the wheel of the M235i early last year, BMW was quick to point out the spiritual link between the small quasi-M car and its ancestors, the 2002 Turbo and the E30 M3, but we couldn't help but think fondly of the more potent 1M Coupe. And while the M235i got a lot of things right, its weight and price took some of the shine off it. But more importantly, the intangibles that those older BMWs nailed was somewhat lacking in the M235i – while fun, it was somewhat distant, unlike the visceral 1M. Until we drive the 2016 BMW M2, those intangibles will remain intangible. But on paper, the M2 looks to be a super-M235i, buffed up with M goodies like an active rear differential and lightened suspension components. But if you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. With the manual it weighs 3,450 pounds, an 85-pound reduction. With the DCT, it's a wash at 3,505 pounds. At least the M2 looks like a proper M car. The side bodywork swells 2.1 inches up front and 3.1 inches in the rear to accommodate wide 19-inch forged wheels wrapped in Michelin Pilot Super Sport tires. The front end takes the M235i theme (itself an adrenaline-injected version of lesser 2 Series cars) and adds steroidal menace, with the expected larger intakes to feed the extra engine radiator. Out back, there's a diffuser in the rear tray that the M235i lacks, and the scallops that incorporate the taillights plainly telegraph the extra rear width. It's the M4's handsome younger sibling. Like the M235i to which its clearly related, the heart of the M2 is a 3.0-liter inline-six that inhales through a TwinScroll exhaust manifold-integrated turbocharger. High-precision direct injection, Double-VANOS, and Valvetronic are all present and accounted for, with some M goodies like pistons and crank bearings trickling down from the M3 and M4. The result is 365 horsepower at 6,500 rpm and 343 pound-feet of torque available from as low as 1,400 rpm.
