BMW NA president says i3 beats Tesla EVs thanks to lighter all-around footprint

Those waiting for a full-out brawl between Tesla Motors head Elon Musk and BMW North America chief Ludwig Willisch will have to wait a bit. For the bloodthirsty, there are signs of some healthy competition and a little bit of green-car sniping between the two automakers. Willisch, speaking at the Detroit Auto Show earlier this month and responding to questions about Tesla, noted (without mentioning that company by name) that the production process of the German automaker's i3 plug-in was "greener" than any other. According to Business Insider, Willisch highlighted the fully recyclable materials used to construct the i3 as well as the hydropower used at the carbon fiber plant in Moses Lake, WA. Willisch also noted that the Tesla Model S is "very heavy on the braking. Our car feels just like a normal car. That's a big difference when it comes to driving," Automotive News said in a separate report. The latter model weighs about a third less than the Tesla, though it also has an EV range about a third as big. The BMW executive did allow that the Tesla did make a good proverbial "snowplow," not for its driving characteristics but for its ability to get more people conformable with electric vehicle technology. Musk was asked about the i3 in an August conference call and laughed before noting that the i3 had "room to improve." No word on whether Musk and Willisch will be sending each other Valentine's Day cards next month.

BMW M4 Convertible spied with naked top and trunk

Our trusty spy photographers have been at it again, snagging these first images of the forthcoming BMW M4 Convertible without camouflage on its retractable roof and rear deck. You'll recall that this is not the first time we've seen the followup to the M3 Convertible, but that the last batch of images we had were encumbered by a lot more camouflage - this car is virtually naked by comparison.
Not surprisingly, the M4 looks to share its folding hardtop design with the standard 4 Series droptop, and it should operate in a similar manner as well. It's no surprise, but it looks like BMW is going to try and make the transition from M4 Coupe to M4 Convertible as effortless as previous efforts converting the M3 to an M3 Convertible. That should mean that below the beltline, this car is nearly identical to the coupe we saw in Detroit.
As for the camo'd features on these spy photos, the hood, front fascia, rear fascia, quarter panels, side sills and mirrors have all been shown on the M4 Coupe, and don't really bear mentioning. There's been no word of just where the M4 Convertible will make its debut, although considering the lack of disguise on this car, Geneva seems like a likely destination.

Next BMW M3 sedan to be plug-in hybrid?

BMW has a lot in mind for the next-generation 3 Series and 4 Series cars, and we're hearing about it now even though they're not expected for another three or four years. The sedan is expected to be lighter, wider, with a longer wheelbase and a lower center of gravity. Rumored tech updates include the water injection system debuted in production on the BMW 1 Series, and the 4 Series convertible might go back to a fabric top. Now The Detroit Bureau reports BMW insiders have revealed that the next M3 will get a plug-in hybrid drivetrain. We've heard about plug-in variants in the mix for the G20 3 Series using a small displacement four-cylinder, but not on the M3 and possibly M4. The goal is familiar, according to the "several senior company officials:" to improve the performance while reducing the emissions footprint. Apparently, the power unit being worked on uses a "similar engine" to the 425-horsepower, 3.0-liter inline six employed at the moment, with power sent to the rear wheels. Electric assistance would come from a KERS-like unit that would also - and only - send power to the rear wheels. Torque is said to go up at least 73 pound-feet from the 406 lb-ft available currently, and all-electric range might be as much as 20 miles. Plenty of carbon fiber will help offset the weight of the lithium-ion batteries. Despite company obfuscations, we know BMW is working on a hybrid powertrain for a vehicle rumored to be called either i5 or i7, and would use one or two electric motors to drive the front wheels while the traditional ICE drives the rear wheels. This potential M3 and M4 powertrain would be an offshoot of that engineering. Automobile speculates there will be electric turbochargers and a horsepower number around 500. Related Video:
