10.25.08 - Information and Common Myths with the Diesel
Clean Diesel comes to the Jetta
Did you know the 2009 Jetta TDI will be the ONLY clean diesel vehicle available in it segment? Couple that with the fact that the new TDI engine is 50-state compliant, and you have one unique vehicle on your hands. With the introduction of the new clean diesel TDI engine in the 2009 Jetta sedan, Volkswagen is building on its 30 years of diesel heritage in the United States.
- 2.0L four-cylinder, 16 valve TDI engine
- 140 horsepower and 236 lb-ft of torque
- Reduces NOx emissions by up to 90 percent
- Meets the most stringent Tier II/Bin5 standards
All Around Performer
Diesel is less sensitive to varying driving conditions and engine loads (e.g. driving in mountainous areas or using accessories in cold weather). Anyone who values great fuel economy and low CO2 emissions and is concerned about global warming can realize as much benefit from diesel as from hybrid--and maybe more, depending on driving habits.
Clean Diesel: sound like an oxymoron? Not these days. Let's set some things straight about this efficient fuel that's changing all the rules.
DIESEL MYTH #1: Diesel stinks.
Not anymore. Clean Diesel is ultra-low sulfur fuel. Sulfur was the part that stunk. Ultra-low sulfur fuel has 97% less sulfur than other diesel fuel, radically reducing emissions. And the stink.
DIESEL MYTH #2: Diesel is dirty.
Nope. We call it Clean Diesel for a reason. The VW TDI Clean Diesel engines have advanced emission-capturing technology, drastically reducing the amount of CO2 they release. This means that what comes out of the tailpipe is much cleaner than diesels of the past. The dirty diesel smoke associated with old diesel engines resulted from unburned or partially burned fuel. VW TDI Clean Diesel engines use computerized fuel control and common rail fuel injection to virtually eliminate this diesel smoke with higher injection pressures and therefore better atomization.
DIESEL MYTH #3: Diesels are noisy.
Nein. Diesels of old have long been known for their loud clattering engines, but clatter no more. Volkswagen TDI Clean Diesels use "pilot injection" which quiets the engine, while provides more torque than equivalent gas-based engines with less noise than ever before.
DIESEL MYTH #4: Diesels lack "oomph."
Remember, the "T" in TDI stands for turbocharged. New Jetta TDI and Jetta Sportwagen TDI engines are quite fast, out-sprinting both diesels of the past, and other alternative fuel vehicles of the present. The Jetta TDI Clean Diesel models also deliver big torque, even more than equivalent gas-based engines, at a whopping 236 lbs-ft of torque!
DIESEL MYTH #5: Diesel fuel is found mainly at truck stops.
No, truckers are found mainly at truck stops. With the growing popularity of diesel-engine vehicles, more and more gas stations are adding diesel pumps every day. Look for this trend to continue.
