NEW 2015 Chevrolet Trax - Design

Sporty and modern, Trax blends small-car agility with the utility of an SUV, including up to 48.4 cubic feet (1,371 liters) of cargo space. It's Chevrolet's seventh small-vehicle launch in less than four years. During that time, the brand's share of the small-, compact- and mini-car segments has more than tripled -- up 221 percent.

Trax is powered by a power-dense Ecotec 1.4L turbocharged four-cylinder engine backed by an efficiency-enhancing six-speed automatic transmission. The engine is expected to be rated at an SAE-certified 138 horsepower (102 kW) and 148 lb-ft of torque (200 Nm) between 1,850 and 4,900 rpm.
The wide rpm range for the maximum torque -- a specific trait of turbocharged engines -- helps it deliver a more confident driving experience, with a strong feeling of power across the rpm band. The turbocharger's on-demand performance also contributes to efficiency because it enables greater power when needed with the lower fuel consumption of a small-displacement engine when it's not.
The turbocharger is integrated within the exhaust manifold, for reduced weight and greater packaging flexibility. A solid cast crankshaft and forged connecting rods deliver additional durability to support the engine's pressurized power and torque.
A Hydra-Matic 6T40 six-speed automatic transmission with TAPShift control is matched with the 1.4L turbo engine. It has a unique design, with the planetary gearsets positioned on the same axis as the engine crankshaft centerline, making the entire powertrain unit shorter fore-to-aft. This design enables a shorter overall vehicle length, increased interior space, enhanced safety crush zones and lower weight.
A "steep" first gear and a "tall" overdrive top gear to achieve a wide ratio spread of 6.14:1. This allows Trax to achieve robust acceleration, as well as fuel efficiency and lower engine noise at highway cruising speeds.
