Overview

The 2015 GMC Sierra 2500HD Regular Cab is a prominent contender in the fullsize pickup truck segment, competing primarily with the Ford F-250 SuperDuty Regular Cab, the RAM 2500 Regular Cab, and the Chevrolet Silverado 2500HD Regular Cab. Prices start off at MSRP $33,195 with the base work truck trim reaching all the way to the top SLE trim carrying an MSRP of $41,555, for a total of 2 trims being offered. With multiple powertrain and cab options available across multiple trims, there is a Sierra 2500HD for everyone. The GMC Sierra 2500HD regular cab offers 2 exciting powertrains, each offered as both RWD and 4WD.

The base engine is a 6.0L V8 engine capable of making 360 horsepower and 380 lb-ft of torque. This engine is rated for a towing capacity of 13,000 pounds. The second engine is a larger 6.6L turbocharged diesel V8 engine making 397 horsepower and carrying a towing capacity of 17,900 pounds. Both engines are mated to a 6-speed automatic transmission. The GMC Sierra 2500HD regular cab only comes with a 8 feet bed. All in all, the GMC Sierra 2500HD regular cab delivers an exciting package, both in terms of performance and looks. The rugged and masculine exteriors are offered in 9 attractive colors.

Buying Advice

There is no doubt that the top level SLE trim makes the most sense, since the base trim lacks comfort and is solely built as a workhorse. The work truck certainly won’t be necessary unless you need a vehicle for commercial work purposes. If not, the SLE trim should be the ideal choice, as it offers better tech and comfort levels.
