The VQ is a family of V6 automobile petrol engines developed by Nissan and produced in displacements varying from 2.0 L to 4.0 L. Designed to replace the VG series, the all-aluminium 4-valve per cylinder DOHC design debuted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Changes from the VG engine include switching to a timing chain from a timing belt, and relocating the water pump from the outside of the engine to inside the timing cover where the pump is driven by the timing chain. Later versions featured various improvements, such as variable valve timing, and NEO-Di designated VQ engines replace MPFI with direct fuel injection.

The VQ series engine was honored in a record 14-straight selections by Ward's 10 Best Engines from the list's inception until 2008.[1]

produces torque (N⋅m)	334 ~ 371 @ ????rpm

The 3.5 L (3,498 cc) VQ35DE is used in many modern Nissan vehicles. Bore and stroke are 95.5 mm × 81.4 mm (3.76 in × 3.20 in). It uses a similar block design to the VQ30DE, but adds variable valve timing (CVTCS) for the intake. It produces from 231 to 304 PS (170 to 224 kW; 228 to 300 hp) of power and 246 to 274 lb⋅ft (334 to 371 N⋅m) of torque depending on the application.

The VQ35DE is built in Iwaki and Decherd, TN. It was on the Ward's 10 Best Engines list from 2002 through to 2007 and again in 2016. It features forged steel connecting rods, a microfinished one-piece forged crankshaft, and Nissan's nylon intake manifold technology. It has low-friction molybdenum-coated pistons and the intake is a high-flow tuned induction system. Since its inception Nissan has improved upon the VQ35DE with changes keeping it an efficient class leading V6 engine. The engine was updated in 2005 as the VQ35DE Rev-Up. It included variable exhaust timing, a higher rev limit, and a revised oil pump, boosting the output to 297 crank horsepower. This motor was only found in the manual equipped 350z for the 2005-2006 and the manual equipped G35 2005 through 2007 model years.

A modified version of the VQ35DE, called the S1, is produced by Nismo (Nissan's motorsports and performance division) for the Fairlady Z S-Tune GT. It produces 300 PS (221 kW; 296 hp) at 7,200 rpm, a higher rev-limit than that of the original VQ35DE.

VQ35HR

[edit]

VQ35HR
displacement	3,503 cc
redline	7,500 rpm
BORE & STROKE	95.5 mm × 81.4 mm
compression ratio	10.6:1
produces HP	302 ~ 311 @ 6,800 rpm
produces torque (kgf⋅m)	34.9 ~ 36.5 @ 4,800 rpm
produces torque (Nm)	342~358 @ 4,800 rpm
produces torque (ft-lb)	252.43 ~ 264.01 @ 4,800 rpm

The VQ35HR engine was first seen in the US with the introduction of the updated 2007 G35 Sedan model, which debuted in August 2006. Nissan updated the VQ line with the addition of the 3.5 L VQ35HR (for "High Revolution"). It produces 315 PS (232 kW; 311 hp) (US market: 306 hp (228 kW; 310 PS) using the revised SAE certified power benchmark) at 6,800 rpm and 37 kg⋅m (363 N⋅m; 268 lb⋅ft) at 4,800 rpm, using a compression ratio of 10.6:1. As of 2009, the Infiniti EX35 produces 297 hp (221 kW; 301 PS) and the same torque presumably due to tighter regulations.

It has NDIS (Nissan Direct Ignition System) and CVTC with hydraulic actuation on the intake cam and electromagnetic on the exhaust cam. Reportedly over 80% of the internal components were redesigned or strengthened to handle an increased RPM range sporting a lofty 7,600 rpm redline. A new dual-path intake (two air cleaners, throttle bodies, etc.) lowers intake tract restriction by 18 percent and new equal-length exhaust manifolds lead into mufflers that are 25 percent more free-flowing for all around better airflow. The electrically actuated variable valve timing on the exhaust cams to broaden the torque curve is new over the "DE" engine. The new engine block retained the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8.4 mm to reduce piston side-loads. This modification, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle to allow the engine reliably rev to 7600 rpm. With an increase in compression ratio from 10.3:1 to 10.6:1, these changes add 6 more horsepower (306 hp (228 kW) total + 3 hp ram air effect not measured by SAE testing = 309 hp (230 kW)). Peak torque is up 8 pound-feet (11 N⋅m) from the older "DE" engine at 268 lb⋅ft (363 N⋅m) and the torque curve is higher and flatter across most of the rpm range, and especially in the lower rpm range.

The VQ35HR was utilized in rear-wheel-drive platforms while the VQ35DE continued to power Nissan's front-wheel-drive vehicles. In 2010, Nissan introduced a hybrid version of the VQ35HR, pairing the engine to a lithium-ion battery pack.

The VQ35HR fitted to the following vehicles:

Years	Model	Power output
2007–2008	Infiniti G35	306 hp (228 kW; 310 PS)
2006–2008	Nissan Skyline V36 350GT Sedan	308 hp (230 kW; 312 PS)

2014–2019	Infiniti Q70 Hybrid	Combined: 360 hp (268 kW; 365 PS)

VQ38HR

[edit]

By 2007, Nissan's ambition to increase the competitiveness of the Z33 chassis in Super Taikyu racing resulted in the development of a larger displacement engine based on the original VQ35HR Block. It featured the same bore but longer-throw crankshaft (bore × stroke: 95.5 mm × 88.4 mm). The end result was the VQ38HR powered Nismo Type 380RS-C which went on to dominate ST class 1 racing. The 3.8-liter racing engine in the 380RS-C develops maximum power of more than 294 kW (394 hp; 400 PS), and maximum torque of 421 N⋅m (311 lb⋅ft).[2] In order to use this new engine in Super GT GT500, limited numbers of the engine were reproduced in the street-legal Fairlady Z Nismo Type 380RS. The VQ38HR engine mounted in the 380RS is a detuned, street version of the racing engine used in the 380RS-C. The engine displacement remains the same, while the intake manifold and exhaust, air-fuel ratio, ignition timing, VTC and other specs have been optimized for street use. The engine produces maximum power of 257 kW (345 hp; 349 PS) at 7200 rpm, and maximum torque of 397 N⋅m (293 lb⋅ft) at 4800 rpm.[3]

The VQ38HR fitted to the following vehicles:

2007–2008 Nissan Fairlady Z Version Nismo Type 380RS-C
2007–2008 Nissan Fairlady Z Version Nismo Type 380RS

Production

[edit]

The VQ35HR and VQ25HR engines were built at Nissan's Iwaki Plant in Fukushima Prefecture.[4][5]

VHR series

[edit]

The VHR series is a variation of the VQ-HR engine series with Nissan's VVEL (Variable Valve Event and Lift).

VQ37VHR

[edit]

VQ37VHR
displacement	3,696 cc
redline	7,500 rpm
BORE & STROKE	95.5 mm × 86 mm
compression ratio	11.0:1
produces PS	337 @ 7,000 rpm
produces torque (kgf⋅m)	37.32 @ 5,200 rpm
produces torque (N⋅m)	366 @ 5,200 rpm
produces torque (lb-ft)	269.94 @ 5,200 rpm

It was the first production engine from Nissan using VVEL. It has a compression ratio of 11.0:1, with a displacement of 3.7 L; 225.5 cu in (3,696 cc), thanks to a bore x stroke of 95.5 mm × 86 mm (3.76 in × 3.39 in) and a redline of 7,500 rpm. It is rated at 332 bhp (337 PS; 248 kW) at 7,000 rpm and 270 lb⋅ft (366 N⋅m) of torque at 5,200 rpm, and up to 350 bhp (355 PS; 261 kW) at 7,400 rpm and 276 lb⋅ft (374 N⋅m) of torque at 5,200 rpm.

Although the engine VQ37VHR gains only 2 lb⋅ft (3 N⋅m) and 8 lb⋅ft (11 N⋅m) in the Nissan 370Z Nismo, torque over the VQ35HR and this higher torque arrives at 5,200 rpm vs 4,800 rpm in the VQ35HR, the torque curve itself is improved and flattened via VVEL variable valve timing for better throttle response and low rpm torque.

It is fitted into the following vehicles:
