The 2010 RL is packed with enough safety features to please even the most protective mommies
Safety is a highlight of the 2010 RL's spec sheet, with five stars across the board from the National Highway Traffic Safety Administration (NHTSA). The 2009 model won an Insurance Institute for Highway Safety (IIHS) Top Safety Pick award, but the 2010 model doesn't manage to follow up with another, despite carrying forward the same safety features.
According to MotherProof, "The 2010 RL is packed with enough safety features to please even the most protective mommies," noting the full array of airbags and active head restraints. Those standard safety features also include a strong body structure, six standard airbags, all-wheel drive, anti-lock brakes with stability and traction control, plus tire pressure monitors, and optional radar-based cruise control and automatic curve-following headlights.
High technology also plays a role in safety in the 2010 RL, with Acura's Collision Mitigation Braking System. The CMBS detects potential rear-end collisions from its location behind the front grille, warns the driver, then initiates automatic braking, using millimeter-wave radar technology to keep track of vehicles ahead.
CMBS is bundled with adaptive cruise control (ACC), which adapts speed and distance to the vehicle in front.
"When it sees a car bumper approaching fast, it flashes a dash warning, then hits the brakes and yanks in the seatbelt, a surprising jolt to the sternum that can stop a weak heart the first time," says Car and Driver. It's not perfect, however, as Car and Driver further notes: "It false-alarmed a bit too often in slow-moving traffic, so we turned it off."
Edmunds says, "The system will only intervene if the driver fails to act," which could be "especially helpful if the driver has a medical problem while driving or if they fall asleep at the wheel. Thankfully, only chronic tailgaters will find the system intrusive."
The 2010 Acura RL is one of the safest sedans on the road.
