British firm's fastest model yet packs Chevrolet V8 and Porsche gearbox, with a claimed 250mph-plus top speed

Leicester-based sports car manufacturer Ultima has revealed the new RS supercar, its fastest road-legal model yet and featuring up to 1200bhp.

Based on the firm’s limited-run Evolution, the RS gains a number of modifications and enhancements to the powertrain, bodywork and chassis to maximise performance. 

The gel-coated bodywork of the RS has been designed with a strong emphasis on functionality. A 1780mm rear wing works alongside carbonfibre front and rear splitters and wheel-arch vents to enhance downforce, aerodynamic performance and engine cooling, while the new model’s cabin has been subtly reshaped to reduce frontal area.

There are three powertrain options, each taken from Chevrolet’s range of Euro 6-compliant V8 engines. Entry-level models are powered by the 480bhp LT1, capable of 0-60mph in 3.3sec and more than 180mph. The more powerful LT4 unit packs 650bhp and will take the RS to around 210mph.

The flagship 800bhp supercharged LT5 unit produces 800bhp in standard form, but can be tuned to offer up to 1200bhp, which the company says gives the 930kg RS “the potential to outrun every other road-going hypercar on the planet”. In this form, Ultima says the RS will sprint from 0-60mph in 2.3sec and can exceed 250mph. 

Power is fed through a six-speed manual Porsche gearbox, with the company stating that a PDK unit would not be “in keeping with the ethos of an Ultima”. 

The RS sits atop Ultima’s own 19in lightweight wheels, which are wrapped in high-performance Michelin tyres. 

Stopping power comes from a set of 322mm AP vented discs as standard, but optional 362mm AP grooved units and upgraded six-piston calipers can take the RS from 100mph-0 in 3.3sec, 0.47sec quicker than the McLaren Senna performed in our tests last year.

The model’s fully adjustable suspension system provides nine different angles of attack, with an optional front-end hydraulic lift mechanism enhancing on-road usability. 

Inside, Ultima has installed a fully welded and powder-coated roll-cage, half-leather sports seats with lumbar support, an Alpine infotainment system with sat-nav and Bluetooth options, and a bespoke luggage set with RS branding. 

Pricing has not yet been confirmed, but the company’s website says the model can be bought for the same price as a “mundane new BMW M3”, suggesting it will start from around £60,000. 

Customers can contact the company for a quotation, but Ultima is warning that lead time for a fully built ‘turnkey’ model is currently more than two years. The parts for a self-assembly model can be delivered in 22 weeks.

Ok, wear close fitting goggles to keep your eyes in place!

love this car but the rear does look still a bit outdated and they should do one that is less track ready so to speak.

Oh my LORD!  It's perfect.

This looks amazing. I've searched everywhere for a proper review of an Ultima and can't find anything. The performance figures are insane. Autocar, why not ask for a go in one rather than just rehashing a press release? Could it be that the performance figures will embarrass Ferrari, McLaren, Lamborghini etc..? Best not to annoy the big boys?

I'm sure Ultima could supply you with one for a few days.

Head to Pistonheads forum and go to the Ultima section. Plenty of owners that are more than happy to share their ownership experiences.

Agreed long verdue.......why are the motoring press so scared of this car?

Top Gear never did run a test of the car despite the fact that a 820bhp version lapped the track faster than Schumachers FXX .....on road legal tyres!

They used the car at their stage shows but never tested the car...how weird is that despite testing the Hawk Stratos?

Autocar tested several kit cars including the Bell Lister, but despite my raising the point, no Ultima test transpired.

I cant imagine that Ultima resent the publicity, so is it the supercar manufacturers themselves blocking this?

The Ultima is a fantastic machine with a ultra reliable Chevy V8 (read cheap to maintain), as someone else said, much for the UK to be proud about.

On paper this has the potential to demolish every other production road car around the Nurburgring, including hypercars and track-day cars. And simply given slicks, racing brakes and being stripped out, I have no doubt it'd get very close to the Porsche 919's record time.

On what planet would it? This is a road car, with a lot of track focus. Not a unrestricted race car with F1 like performance. I seem to recall you thought the Senna would get near the 919 at the ring as well, yet Harris recently compared it to the GT3 car round silverstone and it was 7 seconds a lap slower. It wouldnt even get close.

I saw the 650S GT3 vs Senna video too and I was surprised just how much quicker the 650S was. Just proves the point (which Roadster needs) that racing cars are on another level compared to track day cars etc, even exotic ones like the Senna.
