Evolution of the NSX The picture below is a 94 NSX, and the picture on the right is the new 2016 NSX. The first NSX was made in 1990 and had a 270 horsepower 2.0 liter V-6, then later upgraded to a 3.2 that made 290 horsepower! "While its output wasn't exactly impressive when compared to other super-cars from the era, the NSX was incredibly fast due to its low curb weight."- TopSpeed
With the cease in production of the NSX at 2005, the new 2016 NSX has many more advanced upgrades. "At the heart of the NSX’s performance capabilities is an all-new mid-mounted, 75-degree, DOHC V6 engine with twin turbochargers mated to an Acura-developed 9-speed DCT. The V6 engine employs a race-inspired compact valve train and dry sump lubrication system to help lower the center of gravity. The all-new 9-speed DCT delivers synapse-quick gear changes and rev-matching downshifts. The rear direct-drive electric motor, housed between the engine and transmission, supports acceleration, braking and transmission shifting performance. The NSX’s front wheels are driven by twin independent high-output electric motors which deliver instantaneous torque response and dynamic left-to-right torque distribution." - TopSpeed
The physics behind the electric motors that are used on the car can be summed up by the simple equation V=IR this concept is very important on getting the best bang for your buck.
