Tech on wheels: Acura NSX returns as gas-electric hybrid
AFTER a 12-year absence, the Acura NSX returns for 2017 as the first gasoline-electric hybrid supercar, mixing exotic looks and sports-car handling with the latest engine and electric power technology.
A twin-turbo V-6 behind the seats works in tandem with electric motors between the front wheels and at the back of the car to generate 573 horsepower and 476 foot-pounds of torque, all while wearing the fuel-efficiency crown for a high-performance, gasoline-powered sports car.
The 2017 NSX is rated at 21 miles per gallon in city driving and 22 mpg on highways, which is a 17 percent improvement over the last NSX. But the new NSX is more than a fuel-efficient sports car. The electric motors that independently drive the left and right front wheels also provide torque vectoring for all-wheel drive taken to a new level of cornering precision. The electric power adds fast off-the-line starts, then smoothly transitions to robust engine power. And every tap of the accelerator brings instantaneous torque from the electric motors, too, so the NSX feels quick and responsive across a wide driving range.
On sight, the NSX has a low-slung, sleek body. Ground clearance is just 3.7 inches, and driver and passenger drop low into the sculpted seats, where they are perfectly positioned to look at the tailpipes of trucks and SUVs ahead of them. Drivers must watch that they don’t bump the low NSX nose as they enter driveways.
At 87.3 inches wide, the NSX’s cabin feels wider and roomier than expected. Legroom maxes out at a decent 42.8 inches, and headroom is a good 38.3 inches.
Strong engine sounds emanate from behind the seats where the mid-mounted engine resides. But there’s a “quiet” drive mode that tries to keep the car on silent electric-only power if the driver can creep along at less than 20 mph.
Good luck with driving this car that slow: The 3.5-liter, double overhead cam, twin-turbocharged V-6 is longitudinally placed and is visible, under its engine cover, under the glass of the rear window. The engine, which is new for Acura and its parent company, Honda, has both direct injection for regular fuel delivery and port injection for additional power in high-performance driving.
It’s mated to a nine-speed, dual-clutch transmission that can be driven like a typical automatic or shifted manually by the driver without the need for a clutch pedal.
The NSX rides firmly, feels solidly planted to the road and conveys even subtle road imperfections inside to the driver and passengers. Many bumps come through as vibrations, but some can be jarring.
The car stays amazingly flat in turns and curves, and while it can dart aggressively through a slalom, it doesn’t feel lightweight. The new NSX weighs 3,800 pounds, some 600 more than its predecessor, because of its electric motors and lithium ion battery pack.
The NSX controls on the dashboard look like they were pulled out of another Acura. As an example, the NSX doesn’t have an enlarged, vertically positioned display screen, like a computer tablet, the way such screens are in McLarens, the latest Volvos and the Tesla Model S.
The NSX also doesn’t decouple the suspension and engine controls to allow drivers to mix and match their drive experience the way that a McLaren does. (AP)
