Alpina D3 Bi-Turbo torquing its way toward Frankfurt

Few tuners benefit from the kind of factory support that Alpina does, giving the pseudo-aftermarket firm nearly as much official status as BMW's own M division. And this is its latest product.
Set to debut, as expected, at the Frankfurt Motor Show this week is the new Alpina D3 Bi-Turbo, which you can consider, for all intents and purposes, the diesel M3 that BMW never built. While the outgoing D3 (which was Alpina's best-selling model) used a four-cylinder engine, Autocar reports that the new model packs a 3.0-liter, twin-turbo inline-six diesel to drive a respectable 345 horsepower but a mammoth 516 pound-feet of torque to either the rear wheels or all four through the optional availability of xDrive. (European buyers will also be able to choose between sedan and wagon bodystyles.)
The engine is the same as you'd find in the XD3 and D5 (Alpina's diesel performance versions of the X3 and 5 Series, respectively), but in the lighter 3 Series form can propel the D3 Bi-Turbo up to 62 miles per hour in 4.6 seconds and on to an Autobahn-crunching top speed of 173 mph. And as per Alpina tradition, visual cues are minimal, with a subtly optimized aero kit and 19- or available 20-inch alloy wheels. Unfortunately, the 7 Series-based B7 is the only Alpina we get on this side of the Atlantic, but an oil-drenched performance enthusiast can dream.

Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

BMW M4 spied in coupe and convertible form

From the sound of it, we'll have to wait until the Detroit Auto Show to see the production version of the BMW M4, but spy shots show the new hi-po BMW testing recently in both coupe and convertible form. Showing a lot more skin than recent spy shots, these M4 prototypes look very similar to the M4 Concept we saw at Pebble Beach.
Carryovers from the concept car include the funky mirrors, bulging hood and the slotted front fascia vents, but the rear fascia seems to be missing the added flair of the concept and, as expected, the carbon fiber front splitter and exhaust tips are also missing from these M4s. Like the current M3 Convertible, the drop-top version of the M4 will utilize a retractable hard top.
