New Reveal : 2010 Holden Commodore SIDI

Introduction:

With many of the rear-drive family sedans are in-dangered species, the Australians are still primarily the ones who make the cheapest and the most fun out there. Yes, we are talking about the Holden Commodore, which the face of Australian RWD family sedan. The Commodore always had either two options, a base V6, and a massive American V8. For 2010 though, the Commodore SIDI line-up, adds a new small V6, a bigger V6, and the usual V8. Though styling hasn't changed, this still looks fresh, but we'll talk about the design when the next-generation Commodore comes-out.
Powertrain:

The 2010 Holden Commodore SIDI will newly come-up with a base direct-injection 3.0L V6, that puts-out 270 hp and 213 lb-ft of torque. Although this is the smallest V6 in a Commodore for the last decade, this V6 is actually as powerful as the current 3.6L V6. However, also for 2010, the 3.6L V6 is now rated at 281 hp and 258 lb-ft; though this engine is now an option. For the outrageous SS V8, it's the same 6.2L L99 V8 found in the new Chevrolet Camaro, so 400 hp and 395 lb-ft of torque. All engines also have replaced the 4-speed transmission, to Holden's new 6-speed automatic, with "Shift Tronic".
Fuel Economy:

The whole point that Holden actually moved-down for a 3.0L V6 as a base engine, is to save-up fuel and less CO2 for the environment. Holden says that the 3.0L engine gets up to 13% better gas mileage than the 3.6L, at 25 mpg at city, and 31 mpg on the highway. The extra power in the 3.6L engine doesn't get in the way of economy, so this engine get the same gas-mileage as last year. The new V8, with its Active Fuel Management, gets 16 mpg city, and 25 mpg highway.

Future Work:

This model-design of this Commodore will only last for 2010. So the 3.0L V6 Commodore is actually is a tease for the next year's all-new redesigned Commodore, that will come in end of 2010, as a 2011 model. Nonetheless, the next-generation Holden Commodore will get a new base engine, which is probably a turbocharged 4-cylinder, and the new 3.0L will be the mid-range, replacing the 3.6L. But we will always get the muscle V8, making this our favorite V8 muscle-sedan.
