Bentley's idea of future luxury includes holographic butler

Anybody can daydream, and British carmaker Bentley is no exception. Their vision of an autonomous luxury car is taken so far into the future that it will come with a hologram of a butler. This isn't just a fan-made, Photoshopped image designed to stir a little fantasy, but an official image released by Bentley depicting what their cars might look twenty years from now. The "Future of Luxury" concept image is the work of Bentley's design team, headed by German Stefan Sielaff. Sielaff has worked with Audi and Volkswagen interior design for decades, with a short interim over at Mercedes-Benz's Interior Competence Center. Sielaff has been at Bentley since 2015, and his team is hard at work conceiving the direction of luxury cars in the semi-distant future. Even if Bentley is traditionally closer to Alec Guinness than Princess Leia, a holographic interface is an interesting glimpse into the science fiction thought process of today's car design. Other touches seen in the interior concept image have to do with mood lighting, screensaver-style images displayed on the side panels, and a touchscreen music interface that appears to display Beck's 2005 album Guero. Still, 2036 isn't that far in the future that a Bentley passenger wouldn't take the time to write a few letters by hand.

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:

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:
