Ken Block's
'Digital Zebra'
Ford Fiesta ST RX43!

HPI's latest Ken Block car is the Gymkhana GRiD Ford Fiesta ST RX43, featuring the jaw-dropping 'Digital Zebra' look, and it's available first with fantastic HPI Nitro power!

The easy-to-use and powerful Nitro Star G3.0 engine pushes this 1/8th scale replica of Ken's Gymkhana GRiD ride to awesome speeds thanks to its all-aluminum construction and 32,000 max RPM! The WR8 3.0 chassis is based on the Bullet 3.0 monster truck, so it's extra-tough and able to take the rigors of on- and off-road stunt driving, hooning and all-out racing in its stride, never missing a beat! With sealed bevel gear differentials front and rear, 4WD shaft drivetrain, dual disk brakes and a full set of sealed ball bearings, the WR8 3.0 is ready for anything! The WR8 3.0 is also fitted with a 2.4GHz radio system which features a waterproof SF-10W steering servo, a failsafe-enabled receiver protected by a waterproof case, and the fully-featured TF-40 transmitter!

The WR8 3.0 is crammed with awesome features that enhance its durability anywhere you want to take it, including a high ground clearance, skidplate, foam front bumper, optimized rally-style suspension geometry, shock debris guards, mud deflectors on the chassis and much more. It's the ideal machine to race your friends on multi-surface tracks and rally surfaces, or anywhere you like! 


2.4Ghz Radio System

Easy To Drive!

The HPI WR8 cars are super-easy to drive and get familiar with – all you have to do is install a battery, plug it in and switch on the radio and car. It’s that easy! To drive the car, simply pick up the controller with your left hand, put your left index finger into the trigger area, and then put your right hand on the steering wheel – it’s as natural as driving a real car! Turn the wheel to go left and right, and gently pull on the trigger with your left index finger to go forwards. To stop the car, gently push away from you with your left index finger to brake the car from insane top speeds to a gentle stop. It takes seconds to get used to this easy operation, and in no time at all you’ll be ripping off jaw-dropping moves, just like Ken Block in his Gymkhana GRiD head-to-head races!

Replica fifteen52 Wheels and Real Rubber Tires

For the ultimate in replica looks and fantastic performance, every HPI WR8 with Ken Block’s Gymkhana GRiD Ford Fiesta ST RX43 body is fitted with replica fifteen52 Turbomac and Turbofan wheels in a matching wild color scheme. The wheels really help the car stand out as a scale replica, and for extreme performance, the wheels are wrapped with semi-slick HPI tires molded in real rubber. The grippy rubber compound helps the car stick to asphalt or tarmac for real Gymkhana GRiD action, and the treaded design gives you plenty of grip even on dusty paved surfaces!


Tunable suspension

Suspension Just Like Ken’s Gymkhana GRiD Car!

Fans of racing cars, from real ones to little ones, know that to get the best out of your car you need to have a sturdy, tuneable suspension system. That’s why the HPI WR8 uses double wishbone suspension at all four corners, fitted with real coil over oil-filled shock absorbers and thick sway bars front and rear, just like real Gymkhana GRiD cars! Thick main suspension arms are mated to durable uprights fitted with a pair of rubber-sealed ball bearings for performance that matches Ken’s Gymkhana GRiD Ford Fiesta ST RX43.

Fully adjustable

Full Adjustability Just Like The Real Thing!

All this function is nothing if you can’t customize the car to your liking. Although we’ve set the car to be just about perfect right out of the box, you can easily adjust loads of settings, exactly like a real racing car! Ride height, shock angle and more are simple to adjust if you want to dive under the hood – HPI make it easy to be your own Gymkhana GRiD mechanic AND driver! Drive like Ken, or work on his car: it’s easy to do both with the Ken Block WR8 3.0!


Nitro Star Engine


The Nitro Star G3.0 H.O. engine is a super-powerful upgraded engine based on the already strong G3.0 used in the HPI Firestorm and Bullet 3.0 trucks. The engine is fitted with a steel flywheel for smooth idling and a racing-style 2-shoe clutch for excellent acceleration and throttle response. If you want instant wheelspin, you've got it! The power from the G3.0 H.O. engine is unbelievable, and with up to 32,000RPM you'll get screamingly fast speeds at the pull of a trigger! A 2-stage air filter protects the carburetor opening from dirt and dust, and the tall forged aluminum heat sink head allows the engine to keep its cool. An all-aluminum exhaust system unlocks the horsepower from the engine and throws out a real trail of engine exhaust at top speed! 

Disc Brakes


With all the power the Nitro Star G3.0 H.O. puts out, the WR8 3.0 uses disc brakes to slow down, just like real racing cars! Twin steel disc brakes provide all the stopping power that's needed for the car, and are set up out of the box to provide perfect, neutral brake action for predictable control as you approach the corners. The brakes can also be independently adjusted to give more front or rear stopping power, just like on Ken's real Gymkhana GRiD car! The throttle servo that controls the carburetor opening also controls the twin brakes, with tough fiber brake material taking speed off the twin spinning steel discs that rest on the front and rear driveshafts. Control the action with real disc brakes! 


Super-High Detailed Replica

There's no getting around it: this is an amazingly detailed replica of Ken Block's Gymkhana GRiD Ford Fiesta ST RX43! From the front splitter to the rear wing, and from the roof air intake to the amazing fifteen52 Turbofan and Turbomac wheels, this car looks like the real thing! Every detail of Ken’s real Gymkhana GRiD car is replicated in 1/8th scale, from the grilles and headlights to the double-level rear wing and spoiler. If you want to drive like Ken, you’ve got to have his car, and HPI have the only authorized RC replica of Ken’s Gymkhana GRiD car!
