GM is understandably proud of its direct-injection system that helps its vehicles be more frugal while churning out extra power, and according to the company it’s now the brand with the most direct-injected vehicles in its North American lineup.

For those that don't know, direct-injection engines differ from conventional engines in that rather than mixing air and fuel before they enter the combustion chamber, fuel is sprayed directly into the cylinder where it’s mixed with air. As the piston approaches top-dead center, the mixture is ignited by the spark plug, and when the fuel vaporizes in the cylinder, the air and fuel mixture is cooled. This enables the use of a higher compression ratio in the combustion chamber, which improves the engine’s power and efficiency.

In total, GM offers 18 vehicles with direct-injection, including the new 2010 GMC Terrain. Both of the Terrain’s available engines – a new 2.4L four-cylinder and a 3.0L V6 – come standard with direct-injection, with 2.4L-equipped models estimated at 30mpg (7.8L/100km) on the highway - a figure that puts the Terrain at the top of its segment in terms of highway fuel economy.

Additional new GM models with direct-injection include the 2010 Buick LaCrosse, the 2010 Chevrolet Camaro, the redesigned 2010 Cadillac SRX and the 2010 Chevrolet Equinox crossover. They contribute to GM’s global initiative that will see eight distinct direct-injected engines offered in 38 vehicle models around the world next year.

According to GM, direct-injection and its other fuel saving initiatives mean that roughly 700 million gallons of petrol will be saved in 2009, compared to last year’s model lineup.

    So I guess they just forgot to mention that most automakers don't even have 18 different models to put direct injection on huh? I hate it when they say "we have the most models with [insert technology here]" because the numbers is pretty much always more than the size of the model range of the competition.

    Ford makes 18
    Chrysler makes 6
    Dodge makes 12
    Toyota makes 18
    Honda makes 9
    Nissan makes 14

    Hard to see how any of these guys could have 18 di models.

    There were only 4 engines on that list from GM. It's just that they use them in 5 times as many models because they're the biggest platform whores in the business. The only thing on their list I would consider buying is the Solstice. GM needed DI just to catch up to where the Japanese were without it.
