The 2018 Buick LaCrosse is set to become greener thanks to its new electrified version serving as the base model – the 2.5-liter four-cylinder with an eAssist mild hybrid setup will become the standard powertrain.
Perhaps more importantly, the base price is set to go down a notch to $30,490, versus $32,990 for the current model year equipped with the 3.6-liter V6 – the catch is you’ll have to wait for the hybrid powertrain to arrive this fall. Buick hasn’t delivered all details about the new hybrid version either, such as performance and output figures – but they did say the new powertrain should increase the sedan’s fuel economy in the city by 19 percent. The mild hybrid 2.5-liter four-cylinder setup comes with a motor generator unit instead of a classic alternator, as well as a 0.45 kilowatt-hour lithium-ion battery.
The powertrain will feature stop/start, and the electrification even adds an extra boost of torque when accelerating off the line – while regenerative braking will keep the battery replenished. Buick even uses active shutters in the upper and lower front grilles to aid fuel economy. Meanwhile, the 3.6-liter V6 is now offered with a nine-speed automatic gearbox, as well as all-wheel drive as an option for the Essense trim level, and there are also three new exterior shades – Satin Steel Metallic, Dark Slate Metallic, and Red Quartz Tintcoat.
