The Nissan 370Z (known as the Fairlady Z Z34 in Japan) is a sports car manufactured by Nissan Motors. It was announced on October 29, 2008 and was first shown at an event in Los Angeles ahead of the 2008 Greater LA Auto Show, before being officially unveiled at the show itself. The 370Z is the sixth-generation of the Nissan Z-car line, succeeding the 350Z. Almost every piece and component of the 370Z has been redesigned from the previous model (350Z). It is powered by the VQ37VHR 3.7 L (230 cu in) DOHC V6 with Variable Valve and Lift Control and produces 332 bhp (248 kW; 337 PS). Power delivery to the rear wheels comes through a new 7-speed automatic transmission with paddle shifters or 6-speed manual transmission which features the world's first synchronized down shift rev-matching system, SynchroRev Match. The SynchroRev Match system is only available with the sports package. The differential offered with the Sport Package is indicated to be a viscous limited slip differential. The new driveshaft is made from a carbon-fiber composite material.
Compared to the 350Z, the 370Z has a wheelbase 4 in (100 mm) shorter at 100.4 in (2,550 mm) and an overall length 2.7 in (69 mm) shorter at 167.1 in (4,240 mm). The overall width has been increased by 1.3 in (33 mm), the rear track by 2.2 in (56 mm), and overall height reduced by 0.3 in (7.6 mm). The smaller exterior dimensions and use of more lightweight materials help reduce weight. (Although it should be noted that a 2003–2005 base model 350Z is actually lighter than the 370Z, since federally mandated safety features add weight to models produced after 2008).
The 370Z features a front aluminum subframe, aluminum-alloy engine cradle, aluminum door panels, an all-aluminum hood, and an aluminum hatch. Front body torsion rigidity is improved by 10 percent with an extensively revised body structure which includes a new front suspension cradle to reduce front body lateral bending, new rear structural reinforcements, and an underbody "V-bar" to help reduce rear lateral bending. Rear body torsion rigidity is improved by up to 22 percent and rear body vertical bending rigidity is improved by up to 30 percent. Additional enhancements include the use of a carbon fiber composite radiator housing and strengthening of the rear fender and hatch areas. The new structure weighs slightly less than the 350Z.
The 370Z uses a front double wishbone suspension, with forged aluminum control arms and steering knuckle, the rear multi-link suspension uses a forged aluminum upper control arm, lower arm and radius rod, the toe control rod is steel and wheel carrier assembly is aluminum. The refreshed 2013 model uses new dampers with the Sport package models. The brakes have been changed from the more expensive Brembo racing brakes to Nissan branded brakes which are manufactured by Akebono. The coefficient of drag is 0.30 and 0.29 with the Sport Package, figures identical to the 350Z.
The NISMO version was introduced for the 2009 year model. The engine produces 350 hp (260 kW) at 7,400 RPM and 276 lb·ft (374 N·m) at 5,200 RPM with revised ECU settings and exhaust setup. Transmission choice is limited to a 6-speed manual with Nissan's new "SynchroRev Match" function. Handling is improved via stiffened springs and stabilizer bars compared to the 370Z Coupe. Other equipment includes 19-inch RAYS forged aluminum-alloy wheels with Yokohama ADVAN Sport Y-rated tires (P245/40ZR19 front, P285/35ZR19 rear), 14.0-inch front and 13.8-inch rear vented rotors, NISMO Sport Brakes with 4-piston front and 2-piston rear aluminum calipers, and a fully integrated chin spoiler.
