Volkswagen's New 2011 Jetta Diesel
SAN FRANCISCO, CALIFORNIA - Last week, Volkswagen AG released details of their new 2011 Jetta in a press communique that outlined both the European and the North American versions of their new car. The new 2011 Volkswagen Jetta is a completely new design and unlike previous Jetta models, the new Jetta does not share any of its geometry with the VW Golf model. This article concentrates on the new 2011 2.0 L TDI 'Clean Diesel' model to be offered in the United States and the two new 2011 European high efficiency Jetta BlueMotion diesel models - 1.2 L TSI and a 1.6 L TDI version that use Volkswagen's BlueMotion technology.
The new 2011 Jetta is 3.54 inches (9 centimetres) longer than the previous version, measuring 182.7 inches long or 4.64 metres. For safety, the new Jetta has six standard passenger airbags as standard equipment (driver, passenger, and front and rear curtain airbags for all passengers. As an option, an additional two rear side airbags can be ordered for the car if desired. Volkswagen has incorporated a new high frequency crash detection system for the airbags that help them deploy differently depending on the severity of a collision.
Inside the new Jetta, there is a new climate control system available on both the U.S. and European models as well as a new Keyless Access and a satellite navigation system, with a further premium satellite navigation system available in Europe. For both the United States and Europe, every new 2011 Jetta will be equipped with a 60/40 split folding rear seatback, which helps to provide significant additional cargo space to the car when the driver requires it, plus the option of varying the cargo/passenger carrying capablity using the split rear seat.
In the United States, the new Jetta, with the available 2.0 L TDI 'Clean Diesel' engine, is equipped standard with the SE2 option level plus the trip computer, a leather multifunction steering wheel, leather gearshift grip, leather parking brake lever, 4-wheel disc brakes, and the 16 inch "Mambo" alloy Wheels. The 2.0 L TDI Clean Diesel uses common rail injection with 'piezo' technology to measure precise amounts of fuel, allowing for up to seven fuel delivery injections for each cylinder cycle.
The U.S. 2.0 L TDI Clean Diesel Jetta is turbocharged and can reach 0-60 mph in 8.7 seconds using its high maximum torque of 320 Newton metres to achieve the acceleration capability. The U.S. 2.0 L Clean Diesel Volkswagen Jetta engine is certified for sale in all 50 states of America and has a 42 U.S. mpg highway rating and a 34 U.S. mpg combined city/highway rating.
In Europe the new 2011 Jetta can be equipped with either a 1.2 TSI or a 1.6 TDI diesel incorporating Volkswagen's high efficiency BlueMotion technology. There are additional diesel engine variants available for the new Jetta in Europe, but this article concentrates on the BlueMotion technology engines as these are the highest efficiency. The European Jetta with the 1.2 TSI BlueMotion engine achieves a fuel efficiency of 5.3 L/100 km on the European combined cycle and emits 123 g/km of CO2. More impressive is the absolute efficiency derived in the 1.6 TDI BlueMotion model with a combined fuel efficiency 4.2 L/100 km on the European cycle, and emitting just 109 g/km of CO2.
Volkswagen's two Jetta's with BlueMotion diesel technology, the 1.2 TSI and the 1.6 TDI, both include "Start Stop" technology, low rolling resistance tires, and battery regeneration. The European BlueMotion engines are available in either manual transmission or DSG automatic type. The Start-Stop system initiates the engine to shut off briefly and save fuel when the vehicle is at a red light. The engine is then instantaneously re-started when the clutch is disengaged, or on the DSG automatic model when the brake is released.
The other significant technology in the new BlueMotion Jetta's for 2011 is that the BlueMotion technology incorporates a battery regeneration system whenever the vehicle is braking or coasting, using the vehicle's deceleration to charge the battery. With this BlueMotion technology, the alternator has precise charging control and a high capacity battery, which means the system can shut off the charging drag of the alternator at times to reduce load and hence increase fuel efficiency of the powertrain.
On a worldwide basis the transmission availability for the new 2011 Volkswagen Jetta will be either 5 or 6-speed manual gearboxes, or 6 or 7 speed (DSG) dual clutch automatic types.
