All we had known for sure about the future of the Chevrolet Volt was that it will be undergoing a powertrain upgrade in about a year’s time. That is until now. A source inside the company (who did not wish to be identified) confirmed to InsideEVs that the 83 hp, 1.4L engine that is currently in use as an extended range generator for the Volt will “definitely not” be in the 2014 model year that begins production in the summer of 2013.
It is thought that the 1.4L engine found in the Volt today was never the first choice of engineers who were designing the car, but was mated to the platform strictly out of the availability of the engine. When debuting the concept Volt, GM had envisioned a specially designed engine to optimize performance for the Volt, but had to abandon any such plan because of a freeze on all research and development in the period where GM was entering bankruptcy, and the Volt was in development.
When asked about what the replacement engine might be, it was said that apparently a new 2.0L turbo has been thoroughly vetted on the platform, and will most likely see its way into production of the Volt (and upcoming Cadillac ELR). This is the same engine that GM has recently confirmed will also find a home in the Chevy Cruze Deluxe Buick Verano, a car which incidently rides on the same Delta II platfrom as the Volt. The output of the 2.0L turbo currently ranges from 220hp to 270hp.[current electric drive unit (149 hp/273 lb.-ft. of torque) ]
