has announced that mileage-conscious buyers of its all-new Lacrosse luxury sedan
will be able to opt for a 2.4-liter, four-cylinder Ecotec engine as well as the 3.0-liter and 3.6-liter V6s that were confirmed earlier. Rated at 182 horsepower and 172 lb-ft of torque, the Ecotec will be fitted with direct fuel injection and matched with a six-speed automatic transmission, attributes that it shares with the two larger Lacrosse engines. However, the Ecotec will only be available in the front-wheel-drive-only CX model. Buick still plans to offer the entry-level CX with the 255-horse/3.0-liter V6 that was to be its base engine. That powplant also remains standard issue in the step-up Lacrosse CLX that's available in either front- or all-wheel drive configurations. The Ecotec is expected to earn 20/30 mpg city/highway EPA ratings while the 3.0-liter has preliminary marks of 18/27 mpg. No change at the top of the Lacrosse line, where the 3.6-liter six in the AWD CXS will make 280 horses and return 17/26 mpg. Although Buick provided no pricing details on this new Ecotec-equipped Lacrosse CX, it's expected to sticker somewhat below the previously released $27,835 number for the V6 variant. All of these new Buick sedans
are set to arrive in showrooms by late fall.
