Nissan VK engine
motor vehicle engine family
The VK engine is a V8 piston engine from Nissan. It is an aluminum DOHC 4-valve design.
The VK engine was originally based on Nissan's VQ V6 rather than the VH V8 used in previous Q45/Cima models. Changes include: a variable intake manifold, newly designed heads, and a larger drive by wire throttle chamber. The intake manifold directs air through different paths at different engine speeds to optimise low-end torque or high-end horsepower.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Nissan VK engine”, the useful work is to connect “motor vehicle engine family” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q7041077. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2002.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
