This Duramax-powered 2015 Chevrolet Silverado 2500 HD possesses an as-tested price that’s precisely triple the as-tested price of the 2014 Mazda 3 hatchback I drove around for a week back in late May.

The Mazda had half as many cylinders as the Silverado HD, less than one-third the engine displacement, and no turbocharger. The Silverado has 20% more seating capacity, a wheelbase that’s within eight inches of the Mazda’s overall length, 278% more cargo bed volume than the Mazda has cargo capacity behind the rear seats, and 2.6 times the weight.

The Silverado’s 6.6L turbocharged V8 diesel produces 242 more horsepower while generating more than five times the torque. Yes, it’s not quite three times as heavy as the Mazda, but the Silverado has the torque of five Mazda 3s. Mazda’s 3 operates only as a front-wheel-drive vehicle, but the Silverado can send power to all four wheels. Both utilize a 6-speed automatic transmission. (Read More…)
