The Spectre’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Emeya doesn’t offer pre-crash pretensioners.
The Rolls-Royce Spectre has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Emeya doesn’t offer knee airbags.
Both the Spectre and the Emeya have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Rolls-Royce Spectre weighs 755 pounds more than the Lotus Emeya. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
