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.

BMW i8 Spyder gets production nod

BMW could be poised to expand its i8 range, beyond the hardtop version of the plug-in hybrid supercar. A report from Bimmerpost is claiming that the i8 Spyder, which we showed you in concept form at the 2012 Beijing Motor Show, will be heading to production.
The website claims the open-roof fuel-sipper was shown to BMW management last Friday as a production-intent model. Other than that, there's not a lot to tell here. The i8 Spyder should feature all the same mechanical and aesthetic features found on the i8 Coupe, just without the confining nature of a roof. It's unclear when we'll see a production i8 droptop make its debut, although this certainly strikes us as the kind of car that should arrive at the Geneva Motor Show.
While an i8 Spyder does seem like a logical leap for BMW's i sub-brand, we're going to keep this one filed under the rumors category until we hear more.

Alpina B3 Bi-Turbo burns all the midnight oil

We've got good news and bad news for you, boys and girls, from the floor of the Frankfurt Motor Show. The good news is that the BMW M3 has come early, with a diesel, in wagon form - albeit with a different name. The bad news is that it will in all likelihood never make it to America. Which is a shame, because it's awesome.
What we're talking about, of course, is the new Alpina D3 Bi-Turbo. BMW's wickedly talented but lesser know stepchild has created a 3 Series with a 3.0-liter twin-turbo diesel six packing 345 horsepower and 516 pound-feet of torque. You - and by "you," we mean overseas buyers - can choose between sedan or wagon, as well as rear- or all-wheel drive. But the bottom line is a 4.6-second 0-62 time and a 173-mph top speed... from a diesel.
We scoped out the rear-drive wagon Alpina brought to the show, decked out in its signature blue. And you can, too, in the gallery of live shots above, along with the freshly assembled stock photos of both sedan and wagon versions in the gallery below.
