GMC Sierra 1500 6.2-Liter
GMC trucks are often mechanically identical to Chevrolets, but GMC offered higher levels of trim and more features. In 2014, almost accidentally, GMC created a perfect stealth muscle truck in the form of its Sierra with a 6.2-liter V8 engine pushing a healthy 420 hp (via Car and Driver).
With the same engine as the base Corvette, the GMC Sierra was surprisingly agile in a 0 to 60 mph sprint. It took 5.4 seconds to do that with the help of all-wheel-drive. Of course, the full-size trucks don’t have high top speed, but the 2014 Sierra with a 6.2-liter V8 could top 110 mph, which is decent.
