Nissan reveals Sentra Spec‑V concept with 300 hp and six‑speed manual for SEMA

Nissan has lifted the covers on the Sentra Spec‑V concept ahead of the 2026 SEMA Show, turning the standard compact into a track‑minded tribute to the brand’s old SE‑R hot‑hatch. The show car combines an uprated turbo 2.0‑litre four, a six‑speed manual gearbox and large‑car braking hardware to push the little sedan well beyond its showroom specification.

The Spec‑V was created as a thank‑you to the Sentra SE‑R community and arrives 35 years after that model first appeared. Nissan describes the build as a chance to show what is possible with the current Sentra platform rather than a preview of a production model.

Powertrain and transmission

Nissan says the Spec‑V uses the Sentra’s 2.0‑litre four‑cylinder — identified by some reports as the MR20DD — but heavily upgraded and turbocharged to produce 300 hp at the wheels. The company and the press list a range of reinforced internals and fuel‑system upgrades: new rods and pistons, larger injectors, a front‑mount intercooler and a Garrett G25‑550 turbo.

Engine strength and driveline durability have been addressed with stronger main and head studs, a reinforced crank girdle and a lightweight flywheel, and power is sent to the front wheels through a modified six‑speed manual sourced from the Juke NISMO RS paired with a helical limited‑slip differential.

If 300 hp sounds like a lot for a front‑drive compact, Nissan has gone further than most concept cars to make the package believable: the brakes and suspension come from much larger performance models.

Braking is supplied by the same hardware used on the R35 GT‑R NISMO — six‑piston Brembo front calipers biting 15.35‑inch (390 mm) two‑piece discs and four‑piston rear calipers with 15‑inch (380 mm) two‑piece discs. The suspension setup is described as a ‘customer track version’ of the coilovers from the previous NISMO Sentra, with revised damping, external reservoirs on the front shocks, stiffer springs and upgraded anti‑roll bars.

The visual transformation is conspicuous: a Bomex widebody kit, a vented bespoke hood to feed the intercooler, and a GT‑R NISMO rear wing are the headline pieces. Nissan also fitted NISMO LM‑RS1 19‑inch forged wheels wrapped in Yokohama Advan Neova AD09 rubber and routed the exhaust to custom side‑exit pipes.

Inside, the Sentra Spec‑V borrows Recaro seats used in the GT‑R NISMO, a NISMO steering wheel, a custom seat‑belt harness bar and other blacked‑out trim pieces. The build leans hard into parts bin engineering — the sort of cross‑model sourcing that underlines the concept’s purpose as a demonstration of potential rather than a production blueprint.

Nissan will show the Spec‑V in Las Vegas alongside two other special builds for SEMA: a Datsun S30 concept and a Project NAT2 SCCA Touring 2 Z. While some outlets hope a toned‑down, road‑legal Spec‑V could follow, Nissan and several journalists describe this particular car as a one‑off concept that showcases enthusiast engineering more than a near‑production product.

"Nissan has always had passionate fans who aren't shy about telling us what they love and what they'd like to see next, and we love that – a lot of us at Nissan are enthusiasts, too," said Kim Less, vice president of Aftersales & Customer Loyalty at Nissan Americas.

With 300 hp at the driven wheels, GT‑R‑scale brakes and a manual gearbox, the Sentra Spec‑V is plenty extreme for its size. Whether Nissan will translate any of the concept’s ideas into a dealer‑ready sport compact remains unconfirmed, but the car is a clear reminder that the company's engineers — and some of its fans — still value small‑car performance.
