Chevrolet has released a new teaser image of the 2015 Colorado, ahead of its debut at the Los Angeles Auto Show.

Set to be unveiled on November 20th, the model promises to "reinvent what a midsized pickup should be." That's pretty vague but the company says the Colorado will be the "most capable, most versatile and technologically advanced midsized truck in the market."

Engine options remain a mystery but previous reports have indicated the Colorado could be offered with either a 2.5- or 2.8-liter turbodiesel four-cylinder engine. There's no word on US-specifications but the Holden Colorado's 2.5-liter unit produces 150 HP (110 kW) and 350 Nm (258 lb-ft) of torque , while the 2.8-liter unit develops 179 HP (132 kW) and up to 470 Nm (347 lb-ft) of torque.
