A new Chevrolet Cruze model will be shown in New York, and it gets 40mpg. The Cruze Eco and Cruze RS will be introduced next week. The story and more inside.

Chevy will be introducing a new trim level for the four-door Cruze at the New York Auto Show later this week.  The 40mpg Chevrolet Cruze Eco will be joined by a Cruze kitted-out in a new RS aerodynamic package.

The 2011 Cruze Eco uses a turbocharged 1.4-liter Ecotec engine that produces 138 horsepower (103 kW / 140 PS), and up to 200 Nm (148 lb-ft) of torque.  With the engine mated to a six-speed manual transmission, the Cruze will be capable of traveling 500 miles (800 km) on a tank of gas.

Part of the advancement in fuel efficiency is due to a change in the car's aerodynamics, as well as its lightweight 17-inch aluminum wheels.  With the manual, the car sprints from 0 to 60 mph in over 10 seconds, and a second quicker with a six-speed automatic.  Fuel economy with the automatic will be announced at a later time.

"The Cruze Eco delivers hybrid-like efficiency without the price tag," said Chevrolet marketing executive Jim Campbell. "Along with the Volt electric vehicle, it demonstrates how Chevrolet is working to bring new products to market that range from gas-friendly to gas-free."

Meanwhile, the RS package includes a new fascia, fog lights, side moldings, and a rear spoiler.  Inside, the car will also get a new instrument cluster as part of the kit, which will be available on the LT and LTZ trim levels.

Both the Chevrolet Cruze Eco and the Cruze RS will be shown off on 31 March in New York.
