Chevrolet Volt might get new petrol engine in 2014 image

General Motors is getting ready to launch an improved version of the Chevrolet Volt in 2014, which is expected to get a new and more powerful petrol engine.

According to a source within Chevrolet, the current 1.4 liter engine will leave the production line, because it was never wanted by General Motors officials, and it was adopted as a compromise last minute solution because the company couldn’t afford, financially, the development of a brand new engine, as the GM engineers wanted. This problem is about to be solved because rumors are saying that the updated Chevrolet Volt will get a new and more powerful engine, once it will hit the market in 2014.

Even if there is no official word on this subject from the North American based automaker just yet, rumors are saying that the new engine which might make its way under the hood of the future Chevy Volt is the 2.0 liter turbo unit, made for the Delta II platform, the same one used for the Volt model too. The engine is developing between 220 and 270 HP and it’s coming with direct injection and variable valve control. More details on this subject will be announced sometimes next year.

    Unless the power output of the Volt's electric motor is increased to match that of the 2 liter engine, I do not see the point of this: making the engine more powerful will only effect the car performance if there is a corresponding change to the power of the electric motor driving the wheels. Otherwise all the bigger engine will do is decrease fuel economy. Nor do I see the point of using the turbo version.

    Am I missing something here?

    Good post from T from the corresponding GM-VOLT.com thread.
    "I think people are missing the use of this engine in a volt configuration. Theoretically, yes, this engine can produce 270hp, but it is not peak hp that will be used in a Volt configuration. Here, the engine will operate around peak torque levels and that occurs at a very low (260ft-lbs @1500rpm) compared to the 4000rpm required to produce the 93 ft-lbs in the current, naturally aspirated 1.4l volt engine (I understand the volt engine operates in a range of RPMS). At those RPMs (1500rpm and 4000rpm, respectively) and for virtually equivalent power (260*1500 vs 93*4000), I believe that the 2.0l turbo will be 15% more fuel efficient than the NA engine (I calculated the peak airflow for each engine at those rpms and then calculated the hypothetical fuel use based on the air/fuel ratio). Needless to say, I presume everyone here would be happy with a CS mode fuel efficiency of EPA 42.5mpg (EPA 37 mpg *1.15= 42.5mpg @ 1500rpm). [I am being very conservative with calculations too]."
