VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

Bentley Bentayga V8 specs and pics revealed: It's the sporty one

The glitzy, opulent Bentley Bentayga has so far only been available with a twin-turbocharged W12 in the United States, but that's going to change now that the company has unveiled the V8 version. The Bentayga V8 uses a twin-turbocharged 4.0-liter V8 that, despite having two liters less displacement and four fewer cylinders, still makes a healthy 542 horsepower and 568 pound-feet of torque. Those numbers are only official for Europe, though, as numbers for the United States are being finalized. It's not a whole lot slower than the W12, either, with a 0-60 mph time of 4.4 seconds and a top speed of 180 mph. The W12 hits 60 in 4.1 seconds and has a top speed of 187 mph. What is a bit odd is that Bentley is marketing this V8 model as the "sporty" one, despite not being as fast as the W12. In support of the sporty identity, Bentley has endowed the V8 Bentayga with more aggressive looks inside and out with a black grille and unique dual exhaust tips, as well as an optional carbon fiber trim for the interior. To back up the looks, the Bentley Bentayga V8 also has the option of carbon-ceramic brakes. And they're truly massive with 17.3-inch rotors at the front, and 14.6-inch units in the rear. The front rotors are clamped by 10-piston calipers, too. Bentley claims the front brakes are the largest in the world. The V8 Bentayga also can claim a roughly 100-pound weight advantage compared with the W12, though whether you'll notice that in an SUV that weighs over 5,000 pounds is debatable. Pricing and availability haven't been announced for the Bentayga V8 yet. We would expect it to arrive at dealers by the end of the year. It will also likely cost less than the W12 model.

VW announces reworked 6.0 W12 TSI engine

Nobody makes more engines with a dozen cylinders than the Volkswagen Group. They're W12s, of course, owing to the novel shape of their cylinder banks. Now the German industrial giant has announced a comprehensively reworked version of that engine at the same Vienna Motor Symposium where it presented its new 2.0-liter turbo four. The new W12 retains the same arrangement and the same 6.0-liter displacement, but updates it all with the latest powertrain tech. In place of Audi's FSI direct injection and Bentley's TMPI multi-point injection, the engine has adopted a new TSI system. It's also got a pair of new twin-scroll turbochargers, APS-coated cylinders, a new cooling system, active engine mounts, cylinder deactivation, and a stop/start system. And – crucially for application in the upcoming Bentayga – it has an oil circuit designed for off-road use. The revised package now produces 600 horsepower and 664 pound-feet of torque. Considerably more than the 567 hp and 516 lb-ft offered in the Bentley Continental GT W12, but less than the GT Speed, which we suspect will get an even more powerful version of this new engine. It's also more powerful than even the top version of Audi and Bentley's 4.0-liter twin-turbo V8, to make the W12 a more compelling option. Of course that's just as far as the Continental GT is concerned. The W12 has also found use in the Continental GTC and Flying Spur, as well as the Volkswagen Phaeton and Audi A8, and could find further applications under the Flying B emblem and elsewhere in the future. VW says that in the right application (say, in the production version of the Bentley EXP 10 Speed 6 concept, for example), the new twelve-pot could deliver 0-62 times of under four seconds and a top speed in excess of 186 miles per hour.
