Nissan is reviving the Sentra Spec-V name for a SEMA 2026 project rather than a showroom model. The concept uses a turbocharged 2.0-litre engine, a six-speed manual gearbox and performance hardware sourced from several Nissan and NISMO programmes. Nissan’s build sheet lists 300 wheel horsepower, while the company’s US release rounds the figure to 300 horsepower.
The car is a display vehicle, not a production proposal with a price or a confirmed launch plan. Nissan says it is not available for purchase. Its purpose is to revisit the spirit of the Sentra SE-R and show what can happen when a compact sedan is rebuilt around track-focused parts.
A name linked to the Sentra SE-R
Nissan is presenting the project 35 years after the Sentra SE-R arrived in North America. The SE-R became known among enthusiasts as a sportier version of an otherwise ordinary compact sedan. The new Spec-V is not a direct commercial successor. It is a SEMA build, created for an event where manufacturers and aftermarket companies can explore ideas outside normal production constraints.
Auto Express focused on the contrast between the familiar Sentra shape and the hardware fitted to this example. The wide bodywork, oversized rear wing and side-exit exhaust give the sedan a very different purpose on paper. Nissan has kept the Spec-V badge, but the result goes far beyond a trim package with cosmetic changes.
A modified turbocharged four-cylinder
The engine is based on the 2.0-litre MR20DD and has been rebuilt for forced induction and track use. Nissan’s build sheet names JE pistons, Carrillo connecting rods, WPC treatment and cryogenic treatment for internal components. The turbo system uses a Garrett G25-550, while the fuel system adds port injection through a custom manifold spacer, Bosch EV14 550cc secondary injectors and an AEM 400-litre-per-hour in-tank pump.
The Canadian Nissan build sheet lists 300 whp, meaning the figure is measured at the driven wheels. That distinction is relevant because Nissan’s consumer releases normally quote engine output in horsepower without specifying a wheel measurement. The number belongs to this heavily modified concept and should not be treated as the output of a regular Sentra or as a future catalogue specification.
Power goes through a modified six-speed manual transmission from the Nissan Juke NISMO RS. The drivetrain includes a helical limited-slip differential, a lightweight Centerforce flywheel, an FX350 clutch kit and a modified Hybrid Racing short-shifter assembly. Those choices suggest repeated hard use and driver control rather than the quiet, low-effort operation expected from a commuter sedan.
GT-R brakes and NISMO suspension
The braking system is based on an R35 GT-R NISMO conversion. Nissan lists six-piston front calipers with 390-millimetre, full-floating, cross-drilled two-piece rotors. At the rear are four-piston calipers and 380-millimetre rotors. These dimensions describe the concept only and are not part of the equipment list for the production Sentra.
The suspension uses a custom track version of production NISMO Sentra coilovers. The front dampers have external reservoirs, and the spring and damping settings are described as aggressive and track-oriented. NISMO sway bars complete the suspension changes. Nissan does not publish a lap time, top speed or final vehicle weight, so there is no official basis for ranking the concept against production performance sedans.
The wheels are forged NISMO LM-RS1 items measuring 19 by 9.5 inches. They carry 265/35R19 Yokohama ADVAN NEOVA AD09 tyres. The package prioritises grip and steering response. It also implies compromises in ride comfort, tyre cost and everyday practicality, although Nissan has not published road-test data for the car.
Widebody panels and GT-R details
The exterior uses a BOMEX widebody kit, a vented bonnet with a functional intake and a custom side-exit exhaust. The large rear spoiler comes from the R35 GT-R NISMO. A wider front opening exposes the added intercooler, while the side skirts and enlarged arches change the proportions of the standard sedan.
Inside, the concept receives Recaro front seats from the R35 GT-R NISMO, a harness bar, a NISMO steering wheel and custom black trim. Nissan lists the parts as part of this build, not as a packaged conversion for Sentra owners. The company also warns that modifications can affect performance, safety, emissions, durability and certification for road use.
Where the car will be shown
The Sentra Spec-V Concept will be displayed at Nissan booth 21521 in Central Hall at the Las Vegas Convention Center from November 3 to 6, 2026. It will share the stand with Project NAT2 SCCA Touring 2, a Z prepared for SCCA competition, and a Datsun S30 concept using the twin-turbo V6 powertrain from the current Nissan Z.
The exhibition appearance does not confirm a return of the Spec-V name to Nissan dealerships. Nissan explicitly says the car is a concept and is not for sale. Some NISMO or Nissan accessory parts used in the build may be offered separately through dealers, but that is different from selling a 300-whp Sentra as a road-legal production model.
The project is therefore most useful as a boundary marker. It shows the performance potential Nissan wants to explore around the Sentra name while keeping the distinction between an enthusiast demonstration and a customer product. For now, a manual, turbocharged 300-whp Sentra remains a SEMA concept.
