BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.

Even 'Ring taxi drivers need to respect the Green Hell

The Nürburgring Nordschleife has the reputation as one of the most difficult tracks in the world to master - deservedly so. With 14 miles of roadway and about 160 corners over a massive amount of elevation change, the amount of grip can change from turn to turn. As the driver of the famous BMW Ring Taxi learned this weekend after a shunt into the barricades, the 'Ring can bite unsuspecting pros just as easily as amateurs.
The video of the incident below shows the M5 oversteering right into the wall as a phalanx of Porsche models arrive behind it. According to Bridge to Gantry, a website that specializes in news about the 'Ring, the taxi's passengers were picked up by another Ring Taxi and driven off with a fantastic story to tell their friends back home. "The accident happened at low speed, there were two passengers in the car, but no one had at any injuries," said BMW spokesperson Cypselus von Frankenberg to Autoblog via email.
The crash also closed track for over an hour to clean up and to haul the stricken BMW away. When a driver making a living from driving lap after lap at the Nordschleife has a crash even as seemingly minor as this one, it just goes to show why the course has the nickname 'The Green Hell.'

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.
