A closer look at the 2015 BMW M3 and M4

It's fair to say we're going to miss the E92 BMW M3. Its high-revving V8, flame-styled looks and excellent driving character made it quite simply one of the best cars of the 2000s. Its replacements, the new M3 Sedan and M4 Coupe have a lot to live up to.
We still have a few months to wait until we can drive the new cars, but that doesn't mean we can't get excited in the meantime, learning everything we can. To find out, we sent west coast editor Michael Harley onto the Detroit Auto Show floor earlier this week to talk about the new M cars with BMW product manager Victor Leleu.
If you want a concise, but highly informative rundown of these new cars, look no further than this video. Leleu talks about the styling, weight savings and engines in a lot of detail, making this an interview M fans aren't going to want to miss. Scroll down for the full video.

BMW X4 Concept is no Shanghai surprise

"One in four new BMW cars is now a BMW SAV." If you're new to BMW parlance, SAV stands for Sports Activity Vehicle, a vehicle type most of us more commonly refer to as a crossover, and that statistic, which comes straight from the automaker itself, tells you all you need to know about why the X4 Concept you see above exists.
Like its larger X6 sibling, the BMW X4 Concept tries to shove a crossover in a mold shaped vaguely like a fastback coupe. Put another way, the X4 is likely to be a polarizing design, though perhaps not to the extent that the X6 divided opinions. As for us, we definitely prefer the styling of this X4 Concept, with its strong character lines and impressive wheel-to-bodyside ratio, over that of its bigger brother. That said, we're sure the AMC Eagle comparisons will begin in earnest starting right about... now.
Dimensionally, it seems the most obvious machine with which to compare this X4 Concept is the 3 Series Wagon - we're not sure if it will be as spacious inside as the 3 Series Gran Turismo. A two-inch stretch in the wheelbase ought to bring a commensurate improvement in legroom, and a body that's nearly five inches longer should be a boon for cargo capacity. Of course, that fastback roofline will surely cut down on the car's roominess inside, but we'll have to wait for the final production model to judge its true capabilities.

Two rare Alpina BMWs given the Petrolicious treatment

Alpina is getting more and more ink because of because of that rolling cannonade known as the B7 and its closer ties with BMW. The company's tuning business dates to 1962 when Burkard Bovensiepen began fiddling with Weber carburetors, then his company began racing in 1968 and was eventually certified as an automaker in 1983.
Two of its rarer specimens from those early years have gotten a glance from the folks at Petrolicious: the E24 B10 and E24 B7S. Based on the BMW 6 Series, the Alpina versions made one of the most special coupes from the Eighties even more so. According to the video, there were only 44 B10s made, and the turbocharged, 333-horsepower B7S - this was in a luxury coupe in 1982, mind you - saw only 33 examples produced.
You won't be sorry to find out more about them - and see how they run - in the Petrolicious video below.
