For enhanced safety, the front seat shoulder belts of the Volvo C40 Recharge are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW i4 doesn’t offer height-adjustable seat belts.
Both the C40 Recharge and i4 have child safety locks to prevent children from opening the rear doors. The C40 Recharge has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The i4’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The C40 Recharge has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The i4 doesn’t offer front seat center airbags.
The C40 Recharge has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The i4 doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the C40 Recharge. But it costs extra on the i4.
When descending a steep, off-road slope, the C40 Recharge’s standard Off-Road Mode allow you to creep down safely. The i4 doesn’t offer Off-Road Mode.
Both the C40 Recharge and the i4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the C40 Recharge its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 87 vehicles tested by the IIHS. The i4 has not been tested, yet.
