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.

Tesla in talks with BMW about batteries, charging collaborations

With Toyota and Daimler no longer holding Tesla shares, the electric vehicle company might be looking for a new partner – possibly a Bavarian one. In a new interview with Germany's Der Spiegel, CEO Elon Musk confirmed that he has had talks with BMW execs about future collaboration. "We are talking about whether we can collaborate in battery technology or charging stations," Musk said in the interview, according to Reuters. However, a Tesla spokesperson has tempered things by saying no formal agreements are in place at the moment. In the same interview, Musk reportedly praised BMW's use of carbon-fiber-reinforced plastic in its i sub-brand offerings, and said he would like to have a battery factory in Germany in the next five or six years. The possibility of technological cooperation between Tesla and BMW has been a hot topic this year. In June, Musk reportedly met with BMW execs, and the two companies were also rumored to have met with Nissan to discuss charging technology. When Daimler sold off its shares, there was talk of it opening the way for possible collaboration between the two automakers, as well.

Mercedes may be working on a new electric car dubbed 'Ecoluxe'

Automobile has a lengthy piece this month on how the four German mass-market luxury manufacturers each plan to go after Tesla with their own electric vehicles. It was written by Georg Kacher, the magazine's European bureau chief, and the English version came a month after he wrote the German-language original for Autobild. Tesla isn't exactly a threat to the Germans, but, according to the report, the Model S is planting the right kinds of seeds in niches that are important to the luxury players. The thinking is that - in addition to needed electric vehicles anyway for stricter US regulations - it's better to start designing the machinery now. The article posited Porsche's attack would rest on the coming Panamera platform, but a big hurdle would be battery placement. Unable to find one large space for a lithium-ion pack, engineers would instead put batteries everywhere they could, for a supposed tally of some "108 battery pouches" throughout the body. A few days after the Automobile piece, however, Porsche publicly said it had no intention of challenging the Model S, because the enthusiastic driving the brand is known for doesn't jive with useful range. In Kacher's retelling, Mercedes' plans are even more ambitious, supposedly taking aim at the Model S and the coming Model X. It would do this with an investment in excess of $2 billion in a program called "Ecoluxe" – Mercedes has no brand division akin to BMW's i and Audi's e-tron. The new brand would create a four-strong family of bespoke electric vehicles: a smaller platform with a wheelbase around 106 inches and a larger one with a wheelbase around 118 inches. In addition, the range would have "provisions for rear-wheel drive, all-wheel drive, and rear-wheel steering." The numbers are impressive: seating for seven in the larger vehicles, both longer than 16 feet, front and rear storage areas, ratings of up to 610 horsepower and production capacity of 80,000 units per year. When would we see such creatures? Perhaps as soon as 2019. We do know that if Tesla can knock the Model X over the outfield fence, automakers are going to have to do something. We don't know what the chances are that Ecoluxe is Mercedes' first move - but such a plan could help explain the weird Mercedes concept spied in October.
