The iQ’s 0.299 drag coefficient is quite good.

Two powerplants will be offered, a 1.0-liter VVT-i gasoline engine and a 1.4-liter D-4D diesel. The 3-cylinder, 12-valve DOHC gasoline engine is rated 67 horsepower, while the 4-cylinder, 8-valve OHC common rail turbocharged diesel produces 88 horsepower. A new 1.3-liter dual VVT-i gasoline engine with stop-and-start technology will be available later in 2009.

The 1.0-liter engine is mated to a 5-speed manual transmission with a Multidrive continuously variable transmission optional, while the diesel engine is mated to a 6-speed manual. The 1.0-liter VVT-i manual version gets an estimated 56 mpg fuel economy overall, while the diesel variant has an overall fuel economy of 57 mpg.

The driver is also presented with information to allow driving more efficiently. A Gear Shift Indicator on manual transmission models indicates when to shift up or down for best fuel economy. Multidrive models have an ‘ECO’ driving indicator lamp on the multi-information display that encourages more economical driving by signaling when fuel is being saved. Current and average fuel consumption is also continuously shown.
