requirements in the light truck and SUV segment being mandated by Washington over the next few years, it only makes sense for the Dodge Ram and Durango to incorporate the fuel saving technology. Chrysler Group insiders have smiled, winked and therefore hinted that such would be the case in the not too distant future.

For the time being, the Jeep Grand Cherokee will be the only SUV to offer MDS, combining the best in power and fuel efficiency into one package. Those not wanting as much output can opt for an all-new base engine, the same 210 horsepower 3.7-liter SOHC V6 with 235 lb-ft of torque that is currently featured in the top-line Liberty. While the new engine provides smoother, quieter operation, greater power, better space optimization plus improved fuel economy, it will be hard to say goodbye to the venerable 4.0-liter I-6, an engine that's been in the Jeep Grand Cherokee lineup for decades.

efficient 4.7-liter SOHC V8 will soldier on with 230 horsepower and 290 lb-ft of torque.

No matter the engine chosen, all Grand Cherokees will feature a 5-speed automatic transmission, reportedly delivering smoother shifts and improved fuel economy in V6 and V8 applications. The unit mated to the 3.7-liter V6 will be all-new, while the current 545RFE 5-speed automatic will be joined up with the 4.7-liter V8 once again, and become the standard gearbox for the top-line 5.7-liter V8 as well. While it increases the SUV's maximum towing capacity Jeep also says it's been "refined for higher-quality shifts."

The new 2005 Jeep Grand Cherokee will be available across Canada this fall.
