For the 2007 model year, the 350Z was again moderately revised. The VQ35DE V6 was replaced with a new VQ35HR V6. It produced 306 bhp (310 PS; 228 kW) at 6,800 rpm with 268 lb-ft (363 Nm) at 4,800 rpm using the revised SAE certified power benchmark. The VQ35HR had a raised redline to 7,500 rpm and more torque across the rpm range. The hood was redesigned with a bulge reminiscent of the original 240Z to accommodate the raised deck height of the new VQ35HR. In the U.S., trim levels were narrowed down to 350Z (base), Enthusiast, Touring, Grand Touring and NISMO, while in Europe the same trim levels remained. Bluetooth was added for the 2007 model year.
