The NSX has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The DB11 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 DB11 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the NSX and the DB11 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available rear parking sensors.
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 DB11’s 3 year basic warranty expires 1 year sooner.
Acura’s powertrain warranty covers the NSX 3 years longer than Aston Martin covers the DB11. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the DB11 ends after only 3 years.
There are over 7 times as many Acura dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the NSX’s warranty.
On the EPA test cycle the NSX gets better fuel mileage than the DB11 (21 city/22 hwy vs. 13 city/22 hwy).
Regenerative brakes improve the NSX’s fuel efficiency by converting inertia back into energy instead of wasting it. The DB11 doesn’t offer a regenerative braking 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 DB11 doesn’t offer a cap-less fueling system.
The NSX offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The DB11 doesn’t offer ceramic brake rotors.
For better traction and acceleration, the NSX has larger rear tires than the DB11 (305/30R20 vs. 295/35R20).
The NSX’s 245/35R19 front and 305/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the DB11’s 40 series front and 35 series rear tires.
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 DB11 doesn’t offer vehicle monitored tire inflation.
The Acura NSX may be more efficient, handle and accelerate better because it weighs about 200 pounds less than the Aston Martin DB11.
The NSX is 10.6 inches shorter than the DB11, making the NSX easier to handle, maneuver and park in tight spaces.
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 DB11 doesn’t offer automatic dimming high beams.
