The GMC Sierra is all-new for 2007, just like it’s Chevrolet Silverado twin. Also like it’s twin, the Sierra is available with an insane number of options and configurations. You can choose between regular cab, extended cab, crew cab, short bed, long bed, and there are a stunning 5 different engines available. Power is up vs last year, but so is gas mileage. The 5.3 liter engine earns a 16 mpg city / 20 mpg highway rating – that’s pretty solid for such a big truck.
So, what don’t I like about the Sierra? Well, I like power as much as anyone, but who in the world needs 403 horsepower to carry dirt? And since when is it ok to have a 4 speed automatic transmission in a truck that can run well over $40k? And, of course, curtain airbags still aren’t standard. When will it finally become unacceptable to get these things wrong?
All in all though, the Sierra is a powerful offering. There are enough choices for anyone, the power is solid, gas mileage is commendable, and the interior is light years ahead of the last generation.

2007 GMC Sierra Reviews
Jalopnik reviews the 2007 GMC Sierra and gives the handling 4 stars – ‘The new pickup should only have three stars even with the upgrade made by the new rack-and-pinion steering system and the Hotchkiss-type live axle rear suspension. It’s just that the previous model of the truck was just that bad. Still, they’ve included StabiliTrak electro-nanny as a standard feature, and everyone who’s ever driven a fully loaded truck in a quick-brake situation knows, it’s so much better to not get into one — they get an extra star for that.’
Car and Driver reviews the 2007 GMC Sierra and writes – ‘After being relatively impressed with the transformation of GM’s full-size SUVs, we had high expectations of the pickups with which they share so much. They didn’t disappoint. Though we tested only V-8 models, we found all to be smooth and quiet on the highway. Not surprisingly, acceleration was particularly impressive with the top-grade 6.0-liter V-8. However, perhaps we’ve gotten spoiled in recent years, but we remember the day when 295 to 315 horsepower—as found in the 4.8 and 5.3-liter V-8s, respectively—would yield much more excitement.’
Cars Everything reviews the 2007 GMC Sierra and writes – ‘Of the suspensions, the Z83 offers the smoothest ride while the Z85 is slightly stiffer and for those who often tow trailers. The Z71 is set up to enhance off-pavement driving. The Z60 configuration is for what GMC calls “maximum street performance” and includes big 20-inch wheels. The NHT geometry is designed for Sierra owners who need to tow heavier trailers.’
Edmunds reviews the 2007 GMC Sierra and writes – ‘Equipped with the burly 6.0-liter V8, the Sierra’s acceleration is predictably swift, going from zero to 60 in 7.9 seconds and clocking a quarter-mile time of 16 seconds flat. The four-speed is sometimes caught flat-footed, taking a beat or two to downshift and provide a surge of power. Steering feel is much improved over previous GMC Sierras thanks to a new rack-and-pinion design. There’s no longer a massive dead spot on-center and the power assist feels about right for a full-size truck. On long trips, the supple suspension swallows bumps (even with the heavy-duty towing option) while still allowing confident, no-slop handling with a minimum of body sway through the turns. The cabin is impressively quiet, as we recorded a lower sound reading at 70 mph in the 2007 GMC Sierra than we did in an Audi A6 luxury sedan.’
Vehicle Voice reviews the 2007 GMC Sierra and writes – ‘
• Sticker price (MSRP) of $47,145 seems a little steep
• No Sun visor extensions
• No bed liner or spray-in bed liner or composite bed (at over $47K)
• Mammoth windshield Wipers (not blocking visibility) but definitely a distraction
• Radio/CD/DVD/MP3/XM Satellite Radio/Navigation/ Rear Seat Entertainment Package was a little pricey at $3745 USD?
• Unladen the truck did ‘buck’ (or bounce) while at speed (Which is expected from most trucks – especially when the roadway is constructed out of concrete sections)
• Six speed transmission (6L80/6L90) needed. Not a four speed! I would trade cylinder deactivation for a six speed!’
Autobytel reviews the 2007 GMC Sierra and writes – ‘Look closely at the Sierra, or the Silverado, if you prize V8 power with a smooth and responsive ride and a comfortable, nicely designed interior made of quality materials and with ample room to move around. This newest truck offers all of that as well as impressive markers when it comes to the work part of truckdom: maximum towing of 10,500 lbs. and maximum payload of 2,160 lbs. Sure, there are trucks out there that offer more torque (Nissan Titan), larger interior bins and other truck-type benefits. But top to bottom, the Sierra is a truck for grown ups who appreciate a smooth ride and a comfortable seat, no matter what they’re hauling.’
