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.

Audi reveals all-new R8 ahead of Geneva debut

This year's Geneva Motor Show is shaping up to be an absolutely orgy of supercars, but though there will be many that will surely outperform it, few have been as hotly anticipated as the arrival of the all-new, second-generation Audi R8. And here it is. Based around an all-new Audi Space Frame chassis, the new R8 is constructed of a higher proportion of aluminum and carbon fiber than its predecessor. The result is a frame that weighs 15 percent less at just 441 pounds – yet is 40 percent more torsionally rigid - tipping the scales at 3,205 lbs in top spec. Into the middle of that frame Audi has installed a revised version of its 5.2-liter V10, eschewing turbochargers but incorporating new technologies. While other powertrain options are expected to follow, Ingolstadt has gone straight for the top of the range at launch: the 'base' V10 model kicks out 540 horsepower and 398 pound-feet of torque to reach 62 miles per hour in 3.5 seconds and a top speed of 201 mph. The upgraded V10 Plus, however, turns those figures up to 610 hp and 413 lb-ft to reach 62 in just 3.2 seconds, 124 in under ten and a 205-mph top speed. All the while, Audi has also equipped the new ten-cylinder engine with both direct and indirect injection, stop/start and cylinder deactivation systems to cut fuel consumption by 10 percent. It also boasts dry-sump lubrication and a variable exhaust system. Power is transmitted to the road through a seven-speed dual-clutch transmission, a mechanical diff and a revised Quattro all-wheel drive system that can send 100 percent of available torque to either the front or rear axle. Aluminum wishbones suspend it all on 19-inch wheels (or optional 20s), with available variable steering and carbon ceramic brakes (optional on the V10 and standard on the V10 Plus). Underbody aerodynamics generate more downforce and a more slippery form, aided by a deployable rear spoiler (or a fixed carbon wing on the Plus model). All those tantalizing greasy bits are cloaked in fresh aluminum sheet-metal, riding on a track that's 1.6 inches wider: the whole shebang stretches 14.5 feet long, 6.4 feet wide and 4.1 feet high, riding on an 8.7-foot wheelbase. Among the myriad new technologies developed for the new R8 are the full LED headlights with optional laser high beams (where they're legal, at least, which currently doesn't include these United States).

Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.
