Ultima has long been building some of the most
remarkable kit cars ever, and has just unveiled its latest model. Dubbed the
RS, it is set to be unveiled at the Goodwood Festival of Speed and, like Ultima
models, will be sold in a number of configurations.
The small car manufacturer has engineered the RS’
chassis to fit all current LT V8 engines from Chevrolet, starting with the 480
HP LT1. Should customers want even greater performance, they can opt for the
650 HP LT4 from the Z06, or the supercharged 6.2-liter LT5 used in the current
ZR1 modified to deliver 800 HP. For the ultimate in performance, Ultima (natch)
even offers a 1,200 HP upgrade pack for the LT5.
The RS tips the scales at a featherweight 930 kg, depending on the powertrain and options selected. Hence, Ultima
says the entry-level LT1-powered version can hit 96 km/h in 3.0
seconds, 160 km/h in just 6.2 and max out at over 289 km/h.
In LT4 configuration, 0-96 km/h takes 2.5 seconds,
0-160 5.2 seconds, and top speed stands at 337 km/h. The standard
LT5 does 96 km/h in 2.3 seconds, 160 km/h in 4.8 seconds and exceeds 402
km/h. No performance figures have been announced for the tuned, 1,200 HP LT5,
but it doesn’t take a genius to figure it will be significantly faster, taking
it to Chiron/Koenigsegg country. All models come equipped with a
Porsche-sourced six-speed manual transmission.
Braking is provided by AP Racing 322 mm discs and
four-pot calipers at all four corners as standard, while larger, 362 mm discs
with six-piston calipers are an option. Other important aspects of the Ultima
RS include forged 19-inch lightweight wheels and carbon fiber bodywork.
Owners can build the vehicle themselves or have it
built for them at the factory, and can also choose between left- and right-hand
drive configurations.
