Nissan announces new VQ35HR and VQ25HR
Nissan has announced it’s new next-generation V6 engines for front-engined, rear wheel drive vehicles. The new VQ series comes in two displacements – the 2.5 liter VQ25HR and the 3.5 liter VQ35HR. The engines will make it’s debut in the new Nissan Skyline (no, this is not the new GTR) and the Infiniti G35 this autumn.
Improvements include reduction of weight and friction through adoption of asymetrical piston skirt configuration, reduction of piston-side force through lengthening of con rod and the addition of a rudder frame, newly-designed cylinder block with improved cylinder block. Friction is reduced via the use of the world’s first hydrogen-free, diamond-like carbon coating.
The intake valves have continuously variable valve timing control (CVTC) while the exhaust valves have electromagnetic valve timing control (e-VTC). Not sure what the difference is between these two technologies. Intake resistance is reduced through symmetrical twin intakes, and straight intake ports. The exhaust manifold design has also been improved.
The HR in the new engine codes mean “High Revolution”. While the previous generation VQ engine, the VQ35DE had a redline of 6,500rpm and made it’s peak power at 6,200rpm, the new VQ35HR will rev up to a 7,500rpm redline. No power figures were quoted by Nissan, but expect the new VQ35HR to make more than 300 horses. In fact, the number should be about 306hp SAE, which is what the 2007 Infiniti G35 which uses this engine is supposed to be putting out.

The bigger the c.c. more gas to be burn. Why not a hybrid engine for Skyline?

Just wondering about the e-vtc. I don’t think they’re actuating the valves electromagnetically but could they be controlling the damping electromagnetically?

this monster engines will burn lotsa fuels…dono practical or not to use here.

weili,
People who wants hybrid and a skyline in the same car aren’t alot, at least not enough to justify the development cost of such vehicle

I dont give a damn abt fuel cost, I want it in my MYVI!!!! wwwaaaahaha

when european car manufacture starting 2 turn 2 low pressure turbo just 4 the solution 2 save fuel from big cc na for fuel efficiency & emission. eg: mb b200 turbo sl turbo, vw golf gti, saab, volvo t5 etc… japanese do the other way around.

if the next r35 is a 5000cc na skyline gtr. i dont think malaysia market is capable of keeping it on the road here unless the road tax policy amended.
August 24, 2006 @ 3:56 pm
cos the m version lexus IS is a big cc na from this previous forum hint. so the next skyline gtr might as well b a big cc na. the japanese didnt realise they r not as collectable like the europene super car. so my opinion is they kept produce car like evo or wrx sti is a good pratise after all.

I think 2 years ago, there was a restriction for japan auto companies not to manufacture the engine that not over 300 hp, so after the restriction has taken out by Japan goverment, more and more high hp cars are appear on the market. Correct me if I am wrong, but I think I pretty sure about this news.

This high hp is really not suit for malaysia, but for some other countries, like in US, cheap car, big highway with many lanes, and long straight highway, it is
very suitable to have this high hp car on the road.

I really like V-engine sound… even the V6 in Perdana sounds nice… the sound coming out from the exhaust sounds muscular too… but this 3.5 engine I bet not feasible to use it here… only for Aus, US or Euro countries… maybe the 2.5 is big enough for malaysian use…
