From NG_AND_Gasoline fueled engines to Diesel’s with Start/Stop and Regenerative braking.

Wolfsburg, Germany - In Europe, Volkswagen’s BlueMotion Technology is taking the lead by bundling fuel efficient technologies into the automobiles of both today and tomorrow. The recently announced developments include an all-new start-stop system with regenerative braking included in a near future diesel, all-electric drives, full-hybrid systems and multi-fueled ICE’s like the one seen in the new European VW Passat TSI EcoFuel. Volkswagen’s European Passat with the optional 1.4L TSI EcoFuel is at first glance, a somewhat simple natural gas (NG) driven automobile. The fuel system and engine have been extensively reworked to operate on NG just as the Civic GX does here in the states. In addition however, the 1.4L TSI can also run on gasoline for both convenience and more range when a NG filling station is not available while providing both performance and economy never before achieved in a gasoline powered mid-sized automobile. VW’s own EcoBoost The Passat 1.4L TSI EcoFuel uses a 1.4, Direct-injected ICE that has been turbo charged and placed into the mid-sized VW Passat. When driving on NG, the TSI EcoFuel achieves 4.4 kg of NG/100 km. In addition, the 8-gallon gasoline fuel tank allows the Passat EcoFuel a maximum range of over 500 miles. The smallish 1.4L Boosted engine generates 148 HP and 162 Lb-Ft of torque @1,500 to 4,500 RPM allowing the 3,300 pound Passat to accelerate from 0 to 60 mph in an amazing 9.5 seconds with either the standard 6-speed manual or optional 7-speed dual clutch automatic. Within Europe’s CO2 centric metric, this is the first mid-sized sedan that can achieve 60 mph in under 10-seconds and yet still achieve < 120g/km when equipped with the 7-Speed DSG. On a Fuel Economy Equivalent basis, this equates to possibly as high as 38 mpgUS combined on our own 08 EPA which is only bested by the Honda Civic Hybrid and Toyota Prius in the US. VW Passat TSI EcoFuel Along with the 1.4L TSI EcoFuel, the Passat BlueMotion will soon be able to be ordered with an optional detuned 109 HP TDI with a first for VW, Start-Stop and Regenerative braking mild hybrid system. Detailed specs have yet to be released but VW claims a range of over 840 miles on a single tank of fuel! Passat Blue 2.0L TDI appears to include the US Jetta TDI’s 2.0L TDI with its Tier II/Bin5 emission system in tact as it will easily meet the 2014 Euro 6 requirements. Fuel economy of the sedan with the 6-speed manual should be comparable to the current compact sized Jetta’s 33 mpgUS combined on the 08 EPA. At most, a loss of 2 mpg would be the result. With VW’s previous aggressive sales pronouncements for a much larger share of the US market place, we at least now know something about the engines that may help them get there.
