The 3.5 L (3498 cc) VQ35DE is used in many modern Nissan vehicles. It adds variable valve timing and has a bore of 95.5 mm and stroke of 81.4 mm using the same block found in the VQ30DE. Output ranges from 240 hp to 301 hp (179 to 221 kW) and 246 lb·f to 287 lb·f (334 to 390 Nm).

The VQ35DE is built in Iwaki, Japan and Decherd, TN. It was on the Ward's 10 Best Engines list for 2002 through 2007, and the VQ series is the only engine to be honored by Ward's every year since the list's inception.

The VQ35DE has an aluminum engine block and aluminum DOHC cylinder heads. It uses sequential fuel injection (SFI), has 4 valves per cylinder with VVT for optimized opening of intake and exhaust valves, and features forged steel connecting rods, a microfinished one-piece cast camshaft, and Nissan's nylon intake manifold technology. It has low-friction molybdenum-coated pistons. The intake system is a high-flow tuned induction system.

A modified version of the VQ35DE, called the S1, is produced by Nismo (Nissan's motorpsorts and performance division) for the Fairlady Z S-Tune GT. It produces 300 ps, or 285 hp (220 kW), at 7200 rpm - a higher rev-limit than that of the original VQ35DE. The 350Z GT-S concept has a VQ35DE equipped with a switchable Novidem supercharger, producing around 377 hp with the supercharger switched on. The engine may possibly be referred to as the VQ35DER if the GT-S goes into production.

The VQ35DE is featured in the following vehicles:

North American

JDM and other markets

[edit] VQ35HR

Nissan updated the VQ line for 2007 with the addition of the 3.5 L VQ35HR (for "High Revolution" or "High Response"). It produces 315 PS (306hp) @6800  rpm and 358 nm (268lb-ft) @4800 rpm and compression ratio is 10.6:1. It has continuously variable valve timing control (CVTC) with hydraulic on intake cam and electromagnetic on exhaust cam and double overhead cam (DOHC) and 4 valves per cylinder with microfinished camshafts. Redline is 7500 rpm. The intake is a high-flow tuned induction system. It has NDIS (Nissan direct ignition system) and it uses a sequential multi-point fuel injection.

It is used in the following:

  • 2007- Infiniti G35 sedan (The G35 Coupe will keep the current VQ35DE engine for the 2007 model year.)

[edit] VQ37VHR

The VQ37VHR is a DOHC 24 valve (4 valves per cylinder) 6 cylinder engine. The VQ37VHR is rated at 330 hp and 270lb-ft, and has increased displacement (3.7 liters) and a higher compression ratio (11.0:1) that the VQ35HR. Bore and stroke are 95,5 mm and 86 mm and it uses a sequential multi-point fuel injection. Although the engine only gains 2lb-ft of torque at peak, the torque curve itself is improved and flattened all around by as much as 15%. The redline remains 7500 rpm. It is the first time that Nissan used their VVEL (Variable Valve Event and Lift) on a production vehicle.

It is used in the following:

  • 2008 Infiniti G37 coupe, and is expected to show up in the 2008 370Z as well.

[edit] VQ37HRTT

[edit] VQ40DE

The VQ40DE is a 4.0 L variant of the VQ35DE (longer stroke).

Improvements include: continuously variable valve timing, variable intake system, hollow camshafts, lighter crankshaft, and friction reduction (microfinished surfaces, moly coated pistons). It has a silent chain. It has Nissans direct ignition system with platinum-tipped spark plugs. It produces 265 hp @ 5600 rpm and 284 lb-ft @ 4000 rpm.
