Nissan unveils 300hp Sentra Spec-V concept with a six-speed manual

What is under the bonnet

The concept's turbocharged 2.0-litre MR20DD engine is quoted at 300 horsepower at the wheels, against just under 150 hp for the standard Sentra. Nissan strengthened the internals with Carillo rods, JE pistons, stronger main and head studs and a stronger crank girdle, and added a Garrett G25 turbocharger with a front-mount intercooler, a blow-off valve and a more aggressive fuel pump.

A lightweight Centerforce flywheel is paired with a six-speed manual gearbox and a limited-slip differential taken from the Nismo Juke RS. That combination is the detail enthusiasts will fixate on: a manual with a limited-slip diff is the package that made the original Sentra SE-R a bargain favourite, and it is the part of this concept most likely to survive into anything production-bound.

GT-R and Nismo hardware

The build borrows the rear spoiler, Recaro front seats and front and rear brakes from the R35 GT-R Nismo. It also gains a widebody kit, racing harnesses, a custom vented hood and a side-exit exhaust.

Suspension comes from Nismo Sentra coilovers with revised front shocks featuring external reservoirs and a damping profile tuned for the racetrack. The car rides on Nismo LM-RS1 19-inch forged wheels wrapped in 265-section Yokohama Advan tyres.

Pulling GT-R brakes and seats onto a compact saloon is a familiar show-car trick, and it flatters the Sentra's underlying platform more than it says anything about a showroom version. The parts that would matter to a buyer, the engine internals and the manual gearbox, are also the most expensive to put into series production.

Production, pricing and timing remain unconfirmed

Nissan has presented the Spec-V as a concept only and has not announced production plans. No price, on-sale date or market availability has been confirmed, and there is no indication of which countries a production version would reach, including Australia.

The concept follows the lineage of the Sentra SE-R, which used the SR20 2.0-litre engine and offered sporty performance for far less money than premium rivals. Nissan has not said whether any version of the Spec-V will reach showrooms, and the full track-ready specification with GT-R brakes is unlikely to be carried over unchanged.

Volkswagen Group of America has recalled 9,048 Audi Q4 E-Tron and Q4 Sportback E-Tron vehicles in the United States because a high-voltage battery failure could lead to a fire, and it has told owners to stop charging above 80 percent until a fix is ready.

The campaign covers certain 2024 and 2025 model year cars and is listed by NHTSA as recall 26V698000. Audi says it is aware of no crashes, fires or injuries involving its own vehicles tied to the defect.

What Audi has told owners

The interim safeguard is a charging limit: owners of affected cars should charge to a maximum of 80 percent until a permanent remedy exists. The concern involves a state of charge above 80 percent in certain conditions, and the risk is linked to thermal propagation, where one overheating cell spreads heat to neighbouring cells.

Interim notification letters are expected to reach registered owners on December 18, 2026, explaining both the charging cap and the recall itself. Audi has not announced when a permanent repair will be ready, and dealers will carry out the recall work free of charge once one is.

The 80 percent cap is the only safeguard Audi has described so far, which puts the burden on owners to change their charging habits before any letter even arrives. For anyone who routinely charges to full overnight, that is a real change to daily use, not a formality.

The investigation is still open

Audi's Product Safety Committee received reports of thermal events in the high-voltage battery on September 21, 2026, and the recall was opened roughly three weeks later. Volkswagen Group of America filed its Noncompliance Information Report with NHTSA on October 21, 2026, and recall documents state that "the exact root cause remains under active investigation".

Owners can already check whether their car is affected: NHTSA added the vehicle identification numbers to its online lookup tool on October 23, 2026. Public NHTSA documents describe the affected population by model year and total volume rather than a detailed production date range.

A wider problem across the group

The Q4 E-Tron campaign sits alongside a similar issue on the Volkswagen ID.4, which affects 22,524 vehicles with the same unresolved root cause and the same instruction to limit charging to 80 percent. VINs for that ID.4 campaign became searchable on NHTSA.gov on October 6, 2026.

The parallel recalls matter because they suggest a shared engineering question rather than an isolated batch fault, though Audi has not said the two are technically linked beyond the common symptom and remedy. Until the root cause is pinned down, neither brand can tell owners how long the charging restriction will last.

What is still unanswered

Audi has not said how many cars might need battery replacement, what the permanent fix will involve, or when it will be available. The recall documents do not give a production date range, so owners outside the listed model years have no way to judge their exposure beyond the VIN lookup.

There is no Australian recall or local owner notification in the material published so far, and no indication of whether the same charging advice applies outside the US. Buyers shopping a used 2024 or 2025 Q4 E-Tron should run the VIN before agreeing a price, since the charging cap affects how the car can be used day to day.
