To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the GranTurismo Folgore. But it costs extra on the 4 Series Coupe.
Both the GranTurismo Folgore and the 4 Series Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, rear cross-path warning and driver alert monitors.
The Maserati GranTurismo Folgore weighs 963 to 1305 pounds more than the BMW 4 Series Coupe. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
