Volkswagen Going to SCR for All Diesels, Will Increase Electric R&D
Shift In Strategy Major Change from Previous Pro-Diesel Stance
The Volkswagen TDI emissions scandal refuses to go away, and with every week that goes by, another government agency is announcing increased scrutiny, testing, and investigations on the models. In an attempt to restore trust with the car buying public around the world, Volkswagen is pledging to increase research and development efforts in the area of powertrain electrification and equip all of its TDI models in Europe and the U.S. with a urea fluid selective reduction catalyst (SCR), according to Bloomberg.
All 2015 and newer I-4 TDIs sold in the U.S. market are equipped with the next-generation EA288 2.0L TDI, which includes a SCR emissions control system. The engine at the crux of the emissions cheating scandal is the previous-generation EA189 TDI. That engine did not have an SCR system as installed in the Golf and Jetta models but did have an SCR system on the 2012-2014 U.S.-spec Passat midsize sedan.
In addition to tightening up standards and improving technology on its diesel engines, VW is planning on increasing and shifting development resources to electrics and hybrids. The new MQB platform, which underpins the current seventh-generation Golf, is designed to work with conventional gasoline, diesel, hybrid, or fully electric powertrains. Aside from a different floorpan, the all-electric eGolf model shares much of its hardware with the internal-combustion powered models. Volkswagen has said its next-generation Phaeton luxury sedan, due in 2019 or 2020, will have an all-electric drivetrain.
