The two-seat 2015 Nissan 370Z sports car is available as a hatchback coupe or soft-top convertible (Roadster). The coupe comes in base, Touring, Sport, Sport Tech and Nismo trim levels. The base-model 370Z coupe and Roadster come standard with 18-inch wheels and summer performance tires, automatic bi-xenon headlights, LED running lights, keyless ignition/entry, cruise control, automatic climate control, a leather-wrapped tilt-only steering wheel Bluetooth phone connectivity and a four-speaker sound system with a CD player and an auxiliary audio jack. The Roadster gets a power-operated convertible soft top. Available only on the coupe, the Sport trim brings a limited-slip differential, upgraded brakes, special lightweight 19-inch alloy wheels and both chin and rear-deck spoilers. The Touring trim loses these performance upgrades but adds creature comforts like heated side mirrors, leather/simulated-suede upholstery and suede door-trim panels, a rear cargo cover (coupe only), heated seats with four-way power driver adjustment (and four-way manual lumbar adjustment) and four-way passenger-seat power adjustment, ventilated seats (roadster only), an auto-dimming rearview mirror, a 7-inch touchscreen infotainment system with navigation and voice command, a rearview camera, Bluetooth audio connectivity, USB/iPod integration, satellite radio and eight Bose speakers. Every 2015 Nissan 370Z comes standard with antilock brakes, traction and stability control and side airbags.
