Chevrolet will debut the all-new 2010 Equinox next week at the North American International Auto Show in Detroit. A new, 2.4-liter direct injection engine helps the Equinox deliver expected best-in-segment estimated highway fuel economy of 30 mpg -- a 25-percent improvement over the previous model. The 2010 Equinox goes on sale in mid-2009 and will be available in LS, LT and LTZ trim, with available all-wheel-drive.
