LOS ANGELES, CA. November 20, 2008: Volkswagen of America's Jetta 2009 TDI, the country's first-launched 50-state compliant clean diesel vehicle, has been named Green Car Journal's 2009 Green Car of the Year(R). The award was presented at a press conference today at the Los Angeles Auto Show.
The Jetta's 2.0-liter turbocharged direct injection (TDI) engine uses the latest generation of Bosch clean diesel common rail system capable of up to 1800 bar (nearly 30,00 psi) and multiple (up to five) pre- and post-injections through piezo-electric injectors.
Additional vehicle content from Bosch includes the high-pressure pump, engine electronic control unit, diesel particulate filter, low-pressure exhaust gas recirculation pressure sensors, cam sensors, lambda sensors and the hot film air mass sensor, and glow timing electronic control unit.
According to the U.S. Environmental Protection Agency's (EPA) 2009 estimated fuel economy ratings, the Jetta achieves 29 miles per gallon (mpg) in the city and 40 mpg on the highway, making it one of the more fuel efficient clean diesel vehicles on the road today.
Additionally, leading third-party certifier, AMCI, tested the Jetta TDI and found it performed 24 percent better in real-world conditions, achieving 38 mpg in the city and 44 mpg on the highway.
Volkswagen notes that the Jetta TDI has 30 percent better fuel economy and 30 percent better torque compared to the Jetta 2.5 gasoline-powered vehicle.
"We truly are honored to see this vehicle come to market and congratulate VW on this award," said Bernd Boisten, regional president, diesel systems North America, Robert Bosch LLC. "Years ago a diesel-powered vehicle would not have been classified as 'green,' yet alone win a 'green car' award. Clean diesel is a smart choice. Today's modern diesel is clean, fuel efficient and fun to drive.
"This is a historic moment for VW and proves that automakers and suppliers alike are making great strides in the areas of fuel economy, emission reduction and performance enhancements," Boisten added.
He went on to say: "Clean diesel technology combines ultra-low sulfur diesel fuel, advanced engines and innovative aftertreatment technology into a complete package making it one of the greenest powertrain options on the market today."
