2016 McLaren 650S

Safety Comparison

The NSX has standard head airbag curtains which act as a forgiving barrier between the driver and outboard passenger's upper bodies and the window and pillars. Combined with high-strength steel door beams and lower side airbags this system increases head protection in broadside collisions. The 650S doesn't offer side airbag protection for the head.

The NSX has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 650S doesn’t offer all-wheel drive.

The NSX has standard AcuraLink, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The 650S doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the NSX and the 650S have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available rear parking sensors.

The Acura NSX weighs 553 to 642 pounds more than the McLaren 650S. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty Comparison

The NSX comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The 650S’ 3 year basic warranty expires 1 year sooner.

Acura’s powertrain warranty covers the NSX 3 years longer than McLaren covers the 650S. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 650S ends after only 3 years.

The NSX’s corrosion warranty is 2 years longer than the 650S’ (5 vs. 3 years).

Reliability Comparison

The 650S’ redline is at 8500 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The NSX has a 7500 RPM redline.

Fuel Economy and Range Comparison

On the EPA test cycle the NSX gets better fuel mileage than the 650S (21 city/22 hwy vs. 16 city/22 hwy).

Regenerative brakes improve the NSX’s fuel efficiency by converting inertia back into energy instead of wasting it. The 650S doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the NSX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The 650S doesn’t offer an automatic engine start/stop system.

The NSX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The 650S doesn’t offer a cap-less fueling system.

Tires and Wheels Comparison

For better traction, the NSX has larger front tires than the 650S (F:245/35R19 & R:305/30R20 vs. F:235/35R19 & R:305/30R20).

The NSX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The 650S doesn’t offer vehicle monitored tire inflation.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the NSX is 1.4 inches wider in the rear than on the 650S.

For better maneuverability, the NSX’s turning circle is .7 feet tighter than the 650S’ (39.7 feet vs. 40.4 feet).

Chassis Comparison

To almost totally eliminate engine vibration in the passenger area, the NSX has liquid-filled engine mounts. The liquid helps further dampen engine harshness. The 650S uses conventional solid rubber engine mounts.

Ergonomics Comparison

The NSX’s variable intermittent wipers have an adjustable delay to allow the driver to choose a setting that best clears the windshield during light rain or mist. The 650S’

While driving with high beams on, sensitive light sensors standard on the NSX detect other vehicles which could be blinded and automatically switch to low beams. The 650S doesn’t offer automatic dimming high beams.

To help keep the driver’s hands on the wheel, the NSX has standard steering wheel controls for the radio. The 650S doesn’t offer steering wheel audio controls.

Standard AcuraLink for the NSX allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The 650S doesn’t offer factory integrated smartphone program access.

To direct the driver from any location to a given street address, a GPS navigation system is available on the NSX. The NSX’s navigation system also has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The 650S doesn’t offer a navigation system.
