Buick LaCrosse Hybrid (Base price: $31,660)
Gas equivalent: Buick LaCrosse (Base price: $35,285)
Savings on a hybrid: 10.3%
The LaCrosse Hybrid costs 10.3% less than its gasoline-powered sibling, but delivers nearly 50% better fuel economy in city driving.
A so-called "mild hybrid" (a car whose gas engine shuts off when you're idling, then uses battery power to help accelerate from a dead stop), the LaCrosse gets an estimated 25 miles per gallon/city and 36 miles per gallon/highway. That's far above the 17 mpg/city and 27 mpg/highway that a gas-only, front-wheel-drive LaCrosse offers."The LaCrosse Hybrid gets better mileage but is significantly cheaper than the gas-only LaCrosse," Clarke says. "That's a very attractive combination." (GM - Get Report) also made the LaCrosse's already smallish trunk even smaller in the hybrid version to accommodate the drivetrain's large battery pack.
