RZ Ultima Concept by Racer X Design

Who doesn’t know what the Ultima GTR is, right? After all it’s the mid-engine, rear-wheel drive supercar that has held a long list of world records: sub 10 seconds runs up the strip, quickest acceleration from 0 to 100 mph (5.3 seconds), quickest deceleration from 100mph to 0 (3.6 seconds), and many more. The Ultima GTR is powered by an American Speed engine called the Ultima GTR640 that produces 640 bhp (477 kW) and a 720 bhp (537 kW) engine that is called the GTR720. The power-to-weight ratio for the GTR720 is 727 hp (542 kW) per tonne.

The reason we are providing a brief synopsis on the Ultima GTR is because Racer X Design has taken a bit of an interest in this supercar. The kind of interest that could only lead to greatness. Based on an Ultima GTR chassis, Racer X Design has developed a vehicle called the RZ Ultima. The car is destined for those who want an extreme supercar with an attractive look and smoother design. The design team have taken the exaggerated bubbly shape of the Ultima GTR and smoothed it out to provide a cleaner, more simple flow to the line of the vehicle. This ensures the vehicle doesn’t have a trace of the prepubescent-style awkward shape it had before.

The RZ’s styling was designed to leave the chassis and running gear untouched because Racer X Design thinks the way it is built is the way a supercar should be. The Ultima GTR is extremely quick, stylish, and unique. Adding the RZ aesthetic touches takes the Ultima GTR to the next level of prominence.


Available in two powering versions 640 bhp (477 kW) on the GTR640 and 720 bhp.

This specs are only assumption, we don’t know yet how will it perform on track unless it’s already in prototype.

It’s front end is look exactly the same as the Honda NSX. And it’s rear end is the only unique here.

What a sexy and fine looking car!

Well, I might say that this concept really got those eye catching style, and I guess some of us will have a closer look on its beautiful structure.
