Audi A8's active suspension will even protect you in a crash

Audi has revealed yet another system of the upcoming Audi A8 that uses the car's 48-volt electrical system. In addition to a fancy stop-start function, the A8 will have a suspension that can be actuated by electric motors. At each corner of the car is a separate motor connected to an arm that can press down or pull up on the suspension. These motors are controlled by a computer that monitors the road with a camera to determine how the motors should react to improve ride quality and handling. In the instance of some kind of bump or other road imperfection, the car can actively raise the wheel that would go over that bump, to prevent it from upsetting the ride. When going through a corner, the car can direct the motors on the outside to push up to reduce lean, and the motors on the inside to push down to keep the tires pressed to the road. The system can also help keep the car level when stopping and starting. There's yet one more feature of the suspension that is rather interesting. In the event the car detects an impending side-impact crash, it can raise up the side that will be hit, to protect the occupants. By raising up that side, the car increases the chance that more of the energy from the impact will be absorbed by the side rails and floor, which are stronger than the doors and pillars. This nifty new suspension, and the aforementioned start-stop system, will be found on the next-generation Audi A8, which will be officially revealed on July 11. If you can't wait for that, apparently the car has a cameo in Spider-Man: Homecoming, which hits theaters on June 28.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Audi Q7 E-Tron Quattro TDI Quick Spin

The operating word is quiet. This refers both to the sound inside the cabin of the upcoming Audi Q7 E-Tron Quattro TDI – even with the diesel engine running – and the company's public statements about its plan for this powertrain in the United States. Basically, while Europe is getting the diesel plug-in sometime next spring (a bit of a delay), all we know for sure right now is that the US will be getting the Q7 E-Tron, probably in 2018, and it will have either a 3.0-liter turbodiesel or 2.0-liter turbocharged gas engine. You may now place your bets as to which one you think the public (or, more likely, CARB) will go for. We're guessing 2.0T. Despite not knowing if we'll ever see this E-Tron TDI on our side of the Atlantic, we recently spent an enjoyable morning tooling around the hills outside Madrid, Spain. As we said, this beast is seriously quiet, and impressively so. Driving Notes The Q7 is a big vehicle, but with powertrain that combines electric motors and diesel thrust, there's a ton of low-end torque. The official 0-62 time is 6.0 seconds, which is basically the same as the 6.1 seconds of the non-PHEV Q7. The Q7 E-Tron is about 500 pounds heavier than the already-4,700-pound Q7, but because of its trick powertrain, never felt sluggish in the hills of Spain. This Q7 E-Tron is a parallel hybrid, with the 3.0-liter TDI diesel engine and the 94-kW disc motor both able to drive the wheels. Overall, they provide 373 horsepower and 516 pound-feet of torque. Despite the parallel system, the not-quite-powerful-enough electric motor doesn't provide the complete electric drive experience that EV fans might be looking for. For example, the Q7 E-Tron has a top speed of 139.8 mph, but that's only in hybrid mode. In EV mode, its top speed is just 78 mph. Audi's Virtual Cockpit display, first seen in the TT, remains an ideal way to give you a wealth of information in an easy-to-see format. It's just as slick in the Q7, where you can toggle the size of the gauges and then pick what you want the screen to focus on, whether that's speed limits, infotainment information, powertrain usage, speed, or navigation.
