General Motors' Service and Parts Operations website has published a pair of new documents for decoding 2011 model year Vehicle Identification Numbers (VIN) which reveal several new engines. The passenger car list includes a pair of small inline-fours of 1.0 and 1.2-liters displacement. Both engines are listed as port-injected, dual-overhead-cam units from the automaker's South Korean operations, GM Daewoo Automotive Technologies (GMDAT). We're assuming that these are the engines for the Spark mini-car that is due to arrive on our shores sometime during the coming year.
Also on the car list are a pair of 1.6-liter fours listed at 80 and 82 kilowatts. The 80 kW unit matches the 108 horsepower output of the current Aveo engine, so presumably it's a carryover until the new model arrives early in next year. That car is expected to use 110 hp (82 kW) version.
Finally, in the light-duty truck list, there is a 177 horsepower 2.2-liter diesel inline-four. GM has made clear that it has no plans to offer any light-duty diesel engines in the States, so we assume that this is for an export market vehicle, likely the Chevrolet Colorado pickup. The decoder guides are after the jump. A tip of the hat to xeong5!
