The Radical PR6 is what its builder defines as a
“versatile racer that’s at home on both track and hill.” The PR6 is a true “racer’s car,” focusing more on
technical aspects, like lightweight body panels, precision suspension, and
well-tunes gearbox, as opposed to brute strength, like other race car
manufacturers.
The inside of the PR6 is a lot of the same, as it is
purely a race car. It actually somewhat resembles the KTM X-Bow , but with one
fewer seat. The driver is in a central seating position wrapped in a safety
cell that is integrated with the powder-coated carbon-steel frame. The safety
cell meets MSA safety regulations.
The engine is surprisingly underpowered for a sports
car, but for one that weighs as much as a motorcycle, it’s just right. The
engine is a Powertec 1,340 cc 4-cylinder variety, boasting a
double-overhead-camshaft configuration. This engine pumps out a base horsepower
number of 210 ponies at an astronomical 10,500 rpm and 130 pound-feet of torque
at the same peak rpm.
This engine can be tuned to pump up to 280 horsepower,
depending on how deep your pockets are and how brave you are. Surprisingly,
this car is chain-driven. In the place of the driveshaft is a chain, which is
likely as thick as 10 motorcycle chains to minimize power loss due to
elasticity. The transmission is a 6-speed sequential gearbox and connects to
the engine via a lightweight steel flywheel.
This combination of engine and drivetrain gets the
PR6 from 0 to 60 mph in only 3.6 seconds and from 50 to 100 mph in just 6.1
seconds. It also allows the PR6 to hit a top speed of 140 mph.
The Radical PR6 starts off at € 43,390 (US$ 54,185), and
has options that can pump it to well over € 70,000 (US$ 87,415). On the base level,
however, the PR6 is very affordable for the intermediate racer and has plenty
of pop to win races in lower-level classes.
