The i7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Spectre doesn’t offer pre-crash pretensioners.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the i7 are reminded to check the back seat if they opened the rear door before starting out. The Spectre doesn’t offer a back seat reminder.
The i7 has standard PostCrash iBrake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Spectre doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The i7 has a standard Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Spectre doesn’t offer backup collision prevention brakes.
Both the i7 and Spectre have rear cross-traffic warning, but the i7 has Cross Traffic Warning with braking function (automatically applies the brakes) to better prevent a collision when backing near traffic. The Spectre’s Cross Traffic Warning doesn’t automatically brake.
Both the i7 and the Spectre have standard driver and passenger frontal airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
