Audi commits two R18 E-Tron Quattros to final Sebring race for LMP1 cars

We were baffled a few weeks back when the American Le Mans Series and Grand-Am Rolex Sports Car Series announced new classes that will make up their combined racing program in 2014. Gone from the list is the Le Mans Prototype class, otherwise known as LMP1. The LMP1 class has long been the top dog of endurance racing, both in Europe and the US, so we couldn't figure out why this newly minted racing series was jettisoning it like yesterday's donuts.
It appears as if Audi is confused by the move as well. The German brand has announced it will participate in this year's ALMS opening round, the famed 12 Hours of Sebring, as it does every year, and bringing two Audi R18 E-Tron Quattro hybrid race cars with which to compete. Unlike every other year, Audi is treating this year's race as its potential swan song in this famous Florida race.
There's a good reason that Audi is so fond of the 12 Hours of Sebring, as it debuted the gas-powered R8R there in 1999 that kicked off its participation in the upper echelon of endurance racing. The R8R preceded the R8, which debuted at Sebring in 2000 and won that race, starting an amazing career for that car that included five more wins at Sebring. The R8 was followed by the R10, then the R15 and R18, and finally we wind up at today's R18 E-Tron Quattro - all winners, all dominant, all exciting to watch.

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 getting ready for an entire line-up of PHEV models

Despite years of researching any number of standard ICE alternatives, it's becoming clear that different automakers are starting to throw their weight behind their advanced-powertrain technologies of choice. For instance, Toyota is gearing up for its first production hydrogen fuel-cell vehicle next year. Nissan continues to preach the gospel of the battery-electric engine. For Audi, plug-in hybrids appear to be the way to go. The German automaker plans to have a plug-in hybrid version of every one of its models by the end of the decade, UK's Autocar reports, citing comments Audi research and development head Ulrich Hackenberg made at a recent launch event for the A3 Sportback E-Tron. Hackenberg spelled out two variants of the powertrain, including one front-wheel drive version that pairs an electric motor with a 1.4-liter gas engine (this is the version used in the A3), and another to be used for four-wheel-drive vehicles in which an electric motor drives the rear wheels. We couldn't get more information from Audi representatives here on the A3 Sportback E-Tron launch ourselves, and an Audi spokesperson said in an e-mail to AutoblogGreen that the company wasn't commenting further on its plans for plug-in hybrid powertrains in more models. Audi has started pre-sales of the A3 Sportback E-Tron in Germany, pricing the car at about $51,000 with deliveries to start sometime this winter. The vehicle puts out 204 horsepower and can go as far as 31 miles on electric power alone. An exact date has not been set for importing that plug-in to the US, but it will happen some time next year.
