The new Bugatti Chiron Sport can still accelerate from 0-400 km/h (249 mph) and then back to a stop in under 42 seconds, but now it turns corners faster as well. Bugatti drivers have taken the Nardo handling circuit by Chiron storm, shaving five seconds off of the standard Chiron's lap times with the Sport model.
Of course, if you're going to add a few hundred thousand to your price point, there needs to be a little more than some improved track times to show for it. So along with chassis improvements for better lap times, the Chiron Sport also has a new four-pipe exhaust deflector, new wheel options, and carbon fiber windshield wipers.

New S-Class Maybachs will soon get an impressive intelligent headlight upgrade. Digital Light puts a million pixels of resolution into each headlight, and works with the car's sensors and computers to display a bunch of driver-assist information right there on the road in front of you.
Way back in 2009, we covered the Experimental Safety Vehicle, a technology demonstrator from Mercedes-Benz showcasing some pretty out-there technological innovations for the time. Inflating seatbelt airbags, back seat cameras to show you what the kids are up to, and high-friction braking bags that inflate when you're faced with an unavoidable crash and haul the car to a halt much faster than you could with just four tires on the road.
But the one that really caught our imagination at the time was partial main beam intelligent headlights, which had 100 individually controlled LEDs built into them and interacted with sensors on the car to do things like keeping your high beams on and shining them everywhere except into the eyes of oncoming drivers. Or visually highlighting pedestrians who step out on to the road when you've got your low beams on.
Now, nearly 10 years later, Mercedes-Maybach is taking the concept to whole new levels.

Digital Light, which will start rolling out on selected S-Class vehicles sometime in the next few months, gives drivers no less than 2 million pixels in their headlights, allowing incredibly fine tuning of these kinds of effects, as well as opening up the ability to light-paint the road with high-resolution symbols and markings to assist the driver.
We're talking things like big white lines representing the total width of the car, to help you figure out if you can fit through a narrow gap. Big fat arrows pointing to pedestrians that the computer figures are in danger of stepping out in front of you. A speed-sensitive distance mark showing you roughly how far you should stay back from the car in front.

There's also a bunch of other symbols coming; blind spot style warnings will show up on the road as chevrons pointing you back into your lane before you even go to look at the mirrors. Lane keeping symbols. Construction site and low-grip surface symbols, as well as speed symbols.
The selective high beam function has become smarter too, going out of its way only to dim the lights that would shine directly into people's faces. Digital Light will shine high beams on cars, but track and block out the front and rear windscreens, and it will illuminate pedestrians' bodies, but without assaulting their faces with bright light.
Theoretically, of course, pretty much anything could be projected in 2-megapixel black and white resolution, though rules on acceptable content will likely be quite restrictive.

When the trucks first pulled into the presentation site, they made a large U-turn in front of the audience before being parked and the snug fit between the back of the cab and the trailer could be seen to open with what looked like hydraulic rams creating room for the cab to turn. The gap immediately closed again as the rig straightened up, eliminating the gap that creates significant aerodynamic drag on conventional rigs.
That innovative feature on the Semi is entirely in keeping with its streamlined cab and surely contributes to the claimed coefficient of drag (cD) of only 0.36. As Musk pointed out, the $2.7 million Bugatti Veyron supercar has a higher cD of 0.38. Also adding to the vehicle's efficiency is the use of four independent wheel motors on the two rear axles of the cab. This avoids the mechanical losses of driving the wheels from a single motor and enables electronic traction control.
Inside the cab the driver's seat is in the centre and placed well forward, leaving room below and to the rear for what is surely a massive battery pack, and while it appears to be large enough to accommodate a sleeper, it is a day cab configuration. In place of the usual collection of levers and switches there are two touch screens mounted either side of the steering wheel.
