Ultima is a fairly well-known British manufacturer that builds road-going supercars inspired by the prototype race cars that have been thundering down the Mulsanne Straight at Le Mans since the late 1960s. As such, its cars have always been extremely hardcore, but the company has truly outdone itself with its latest creation: the Ultima RS.
The Ultima RS has more downforce than any of Ultima’s previous creations thanks to its full width carbon fiber rear wing, wheel arch vents, rear diffuser, front splitter, dive planes and carefully sculpted bodywork. All these aero pieces were designed in the wind tunnel and ensure the Ultima RS has the grip to match its power.
Speaking of power, it comes from a General Motors-sourced 6.2-liter supercharged LT5 V8 engine, which has been tuned to produce 800 horsepower – up from the 755 horsepower it makes in the 2019 Corvette ZR1. Ultima says the powerplant “can be further tuned to a hypercar power capability of up to a staggering 1200 brake horsepower,” although it did not specify what engine upgrades this would require. Ultima also offers more budget-friendly GM-sourced LS engines in the RS, including a 650 horsepower 6.2-liter supercharged LT4 and a 480 horsepower 6.2-liter LT1.
The 800 horsepower LT5 V8 Ultima RS will allegedly accelerate from 0-60 mph in just 2.5s and top out at 250 mph. It will also complete the quarter-mile in 9.2s at 152 mph. Even the base level LT1-powered Ultima RS has supercar beating performance, boasting a 0-60 mph time of just 3.0s and a top speed in excess of 180 mph.
In all versions of the car, the LS engine will be paired with a six-speed manual transaxle from Porsche. Other notable components include fully adjustable coil spring suspension, an ultra-quick steering rack, AP Racing brakes with 4-piston calipers (6-piston brakes are available too) an adjustable brake bias system, lightweight alloy wheels and Michelin Pilot Sport Cup 2 or Sport 4S tires.
We’re still waiting on pricing and availability for the Ultima RS, but you can learn more about this mad track day creation through the company’s website.
