The performance increase is possible because the LaCrosse’s simple hybrid system doesn’t add a lot of weight. Total curb weight is within 6 lb of the non-hybrid car to offset the extra weight of the 0.5-kWh battery, wiring, and motor/generator, the eAssist LaCrosse uses aluminum in a few key areas wheel hubs and hood, to name two that were previously steel. The 2012 Buick LaCrosse battery is mounted behind the rear seats, and trunk space suffers a bit: its capacity drops from an already smallish 13.3 cubic feet to 10.9. But the LaCrosse has an enormous back seat is a worthwhile tradeoff if you carry more passengers than cargo.
