BMW M6 amped up for track duty by Risden

Risden Engineering is a bit of an unknown, if we're being completely honest - we have yet to report on the company to date, and its corporate website is really an information desert save for the name and a few email addresses. Even the press release that we requested from Risden's contact person is short and vague. That's all pretty much okay with us as long as the shadowy tuners, you know, make good on this sweet-looking BMW M6 racecar thing.
Dubbed the Risden 6R, we're told that the M6 modification will result in a vehicle that is more adept at track work, while still being street-legal. In terms of specifics, we read that a full aero kit will be involved, with one fixed and one retractable rear wing (hard to miss). There are obviously new wheels, and the company has also added a fully adjustable suspension, a four-point roll bar and a new braking system - all while reducing curb weight overall.
Apparently more details are to follow after the 6R's official release in the first quarter of 2013. We wait with bated breath.

BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.

BMW says X5 xDrive40e PHEV will get 55 MPGe

This is one vehicle that Sammy Hagar can actually drive 55. Miles on the equivalent of a gallon of gas, that is. BMW has starting talking about details of its first-ever production plug-in hybrid CUV, and the latest are centered on the model's projected miles per gallon-equivalent figure. Bimmer is now saying the its X5 xDrive40e PHEV will get a robust 55 MPGe on the US EPA scale (on the European scale, the vehicle's expected 77 or 78 grams of CO2 per kilometer would translate to around 70 mpg). The model, which pairs 2.0-liter twin-turbo four-cylinder engine with an electric motor, will be able to go as far as 13 miles on electricity alone, and also hit 75 miles per hour using just the battery. BMW first unveiled the model at the Frankfurt Motor Show in 2013. The CUV, which will have full-time all-wheel drive, will have some guts, too. The model will deliver 308 horsepower, including 111 from the electric motor alone. As a result, the X5 xDrive40e will be able to scoot from 0-60 miles per hour in 6.5 seconds. Not exactly Tesla Model S quick, but peppy nevertheless. US and European sales for the model-year 2016 version will start this fall. The model will be produced at the company's plant in Spartanburg, SC. Take a look at BMW's press release below.
