BMW makes the M4 extra special with a huge wing

BMW has all of the bases covered in its lineup, especially when it comes to its 4 Series models. Don't like going to the track? There's the BMW 430i and 440i, which are available as a coupe and gran coupe. Drivers looking for a track-friendly car that can also be used on the road will be steered toward the M4. BMW even built the hardcore M4 GTS for drivers that spend all of their time on a track. Now, it looks like BMW is trying to bridge the gap between the M4 and the M4 GTS with a special-edition model. Our photographers caught BMW testing an M4 with some extreme aerodynamic components around the Nurburgring. With its aggressive front end, massive wing, and sporty rear diffuser, the prototype M4 appears to be similar to the special-edition M4 Competition Sport that BMW released in Spain. The Spain-only special edition was marketed as a softer version of the M4 GTS with less power and usable rear seats. With a similar look and visible rear seats, this prototype indicates a similar track-focused special edition model. Since the M4 is only a few years old, it's unlikely that BMW is testing a new model, but the automaker could be testing aerodynamic components for a refreshed model down the road. A cheaper, more usable M4 GTS, though, would be the perfect car to round out BMW's current lineup. Related Video:

Bentley to retire aging 6.75-liter V8 with current Mulsanne

The massive 6.75-liter V8 in the Bentley Mulsanne is one of the oldest engines still in production. But it may not be around for much longer. According to Car and Driver, Bentley intends to finally put the big old pushrod V8 to pasture once the current Mulsanne is phased out, thus putting an end to a saga that goes back some 57 years. Powerful as it may be, ever-stricter exhaust emissions and fuel-consumption regulations will see that the L Series V8, originally introduced way back in 1957, doesn't stay in production forever. Whenever the Mulsanne is replaced, it will reportedly get a brand-new twelve-cylinder engine. Bentley is currently the world's largest producer of dozen-pot powerplants. Production of the British automaker's 6.0-liter twin-turbo W12 far outpaces anything from Rolls-Royce, Mercedes-Benz, BMW, Ferrari, or Lamborghini. Over the decades since its introduction, Bentley's long-serving V8 has gone from making an "adequate" amount of power and torque to an impressive 530 horsepower and a positively massive 811 pound-feet (with the help of a couple of turbochargers). Its eventual discontinuation wouldn't be the first attempt on the life of the 6.75-liter engine. When BMW briefly took control of both Rolls and Bentley, it replaced the big engine by a smaller 4.4-liter V8. Customer demand led Bentley to bring the old engine back. It will likely be some time before we get details of Bentley's next powerplant. Models like the Mulsanne and Rolls-Royce Phantom tend to stick around for a long time, and the latest version of Bentley's flagship was just released earlier this year. Related Video:

The next Bentley Mulsanne could go all-electric

How many Bentleys are sold in China, anyway?* That's a question worth asking after the company said it will consider switching the powertrain of its uber-luxe sedan Mulsanne to all-electric from its current gas-guzzling V8 setup. Such a switch would be in the name of adhering to stricter greenhouse-gas emissions limits, especially in countries like China. Bentley executive Hans Holzgartner told Autocar that the company may soon have problems selling a V8-powered Mulsanne in China because government regulators are attempting to push for more zero-emissions vehicles to combat smog problems in the country's largest cities. Oddly, Holzgartner said an electric powertrain is "better suited" to heavier luxury cars than lighter sports cars because of an electric motor's smooth, instant delivery of torque. With the Mulsanne already priced north of $300,000 in the US, passing on the costs of such a huge battery pack will probably be less of an issue than for more typically-priced models. Of course, there would be a ton (almost literally) of battery cells involved. The Mulsanne tips the scales at almost 6,000 pounds, or almost twice the weight of a Nissan Leaf and about 25 percent more than a Tesla Model S. For those curious how the one-percenters live, take a look at Autoblog's recent drive of a Mulsanne Speed. Since this is just being studied at this point, it's possible the next Mulsanne could get a battery-electric or plug-in hybrid version for certain markets, while others would retain a gas engine or offer a choice. Assuming it keeps the gas option, the next Mulsanne will reportedly to switch to a twelve-cylinder engine, likely a version of the Volkswagen Group's W12. As for green cred, let's just say the Mulsanne's couldn't be much worse. Earlier this year, the Mulsanne showed up on the American Council for an Energy-Efficient Economy's (ACEEE) annual list of "meanest" vehicles when it came to environmental sustainability. The Bentley was rated the fourth-meanest vehicle sold in the US, following the Mercedes-Benz G65 AMG, the Chevrolet G2500 Express/GMC Savana, and the Mercedes-Benz G63 AMG. The EPA rates the Mulsanne's fuel efficiency at an absolutely gasoline-swilling 13 miles per gallon combined. * If you're curious, Bentley sold 1,615 cars in China last year.
