The Acura NSX returns for 2005 with no changes. Refreshed a few years back, the NSX continues to offer two different powertrains. The 3.2-liter DOHC V6 is coupled with a six-speed manual transmission producing 290 hp and 224 lb-ft of torque. The second powertrain is a 3.0-liter DOHC V6 engine mated to a four-speed sequential SportShift automatic transmission and generates 252 hp and 210 lb-ft of torque. Standard features on all models include a truck-mounted six-disc CD changer, premium Acura/Bose sound system, keyless entry, automatic climate control, an alarm system, high intensity discharge Xenon headlights, and 17-inch seven-spoke forged aluminum alloy wheels. All 2005 NSXs feature a removable roof panel for open-air driving.
