NISSAN FRONTIER SERVICE MANUAL QR25DE ENGINE
Initially, the Frontier was considered a compact, but beginning with the totally redesigned model year 2005 Frontier (introduced at the 2004 North American International Auto Show), it became more mid-sized (as did rival Toyota Tacoma for this model year). It uses the new Nissan F-Alpha platform and exterior body styling resembles that of the company's full-size Nissan Titan truck. In 2012 production was shifted from Smyrna, Tennessee to Canton, Mississippi.
The new truck has a fully boxed ladder frame. The wheelbase is 125.9 in (3.20 m) with a 205.5 in (5.22 m) overall length. Towing capacity is 6500 lb (2,950 kg). A 4.0 L VQ-family V6, the VQ40DE, is the standard engine, and it produces 261 hp (195 kW) and 281 pound-feet (381 N⋅m) of torque. Also available is the QR25DE four-cylinder engine, which is also found in the Nissan Altima. It produces 152 hp (113 kW) and 171 pound-feet (232 N⋅m) of torque. A six-speed manual is standard with a five-speed automatic optional. Both rear and four-wheel drive are available. Traction control and hill-descent control are also available.
