Mechanically superior, but lacking style
June 26, 2008
My particular 2007 Silverado 2500HD ’Classic’ has the 6.6 diesel engine and is nothing more than then the 2006 model. The new emissions standards did not make it into production until later. As such ’Classic’ models, like mine, do not have the particulate filters or other additional emission controls. I consider it a plus.
It would be unfair to compare any HD truck to a ’ ton, and my personal review for the ride quality 5-stars takes that into consideration. For an HD truck, and compared to other HD truck it rides very smoothly. The interior is spacious, well laid out, with all controls in easy reach. There are innovations that are such good ideas, they should be shamelessly copied. GM has done this with the ’camping mirrors’ option. AKA ford super duty. I have towed our travel trailer with, and without, such mirrors and recommend them highly. I’m waiting for the other major auto makers to copy the ’driver information center’ (DIC) by GM. With the high maintenance costs of a diesel truck it is useful to keep taps on necessary changes of oil, fuel filters, in addition to gallons used, miles-to-empty, MPG, etc.
Mileage is reasonable, if not very good, again compared to any HD truck 20 mpg is good, 13.5 mpg while towing, even better. And towing is where this truck will impress. Under load every shift is smooth; the only indication given that the truck is working is the amount of the fuel consumed. The rear differential (G80) provides superior traction compared to the limited slip enabled Ford I had previously driven.
The only negatives, and I have so far only found 2, are:
The Alison transmission has a supporting cross member that was not made a part of the frame, but bolted below the frame further lowering ground clearance.
The factors tires even are strictly for dry highway cruising. There is really no excuse for such a poor tire. And they are comically small for such a big truck.
