Introduced in late 2012, the RXC Coupe arrived to give Radical Sportscars a road-legal car (in some countries) that had a roof to keep the elements out. Additionally, it arrived with optional air conditioning, carpeting, and more goodies to make road travel a little more comfortable. For the 2015 model year, the RXC Turbo arrived with a 3.5-liter EcoBoost V-6 with 454 horses and 500 pound-feet of torque. Now with the 2016 model year looming and Radical looking to best its existing Nurburgring record, the automaker has released the RXC Turbo 500, which is essentially a hopped-up version of the RXC Turbo.

Boasting all the race-car goodness that made the 2014 RXC so awesome, the RXC Turbo 500 takes things to a whole new level of insanity. But awesomeness aside, is the RXC Turbo 500 really worth the scratch that Radical is asking for it?

2015 Radical RXC Turbo Exterior AutoShow

Note: RXC Turbo pictured here.

Radical failed to detail any changes to the outside of the RXC Turbo 500, so I think it’s safe to assume that it will carry on with the same looks as the standard RXC Turbo. This means that the RXC Turbo 500 will retain the Le Mans LMP-like look. Imagining seeing one of these on the road makes me chuckle a bit, but after a second or two I would be star-struck.

The RXC Turbo 500 will also carry on with the gullwing doors that require a little dexterity to slide through, a pile of air intakes, and that massive rear wing. Yeah, this car’s design is certainly true to its name: Radical.

Length 169.3 Inches

Weight 2,072 Pounds


2015 Radical RXC Turbo Interior AutoShow

Note: RXC Turbo model shown here
Much like the exterior, the interior is not affected by this upgrade. This means that the RXC Turbo 500 features the same multifunction steering wheel, electrically adjustable mirrors, air conditioning, heated windshield, adjustable pedal box, Corbeau-trimmed, FIA-compliant seats, and six-point racing harnesses.

Like the model it’s based upon, buyers can also order bepoke items for the cabin.


2015 Radical RXC Turbo Drivetrain
- image 538972

The drivetrain is what really matters in this update, as Radical took the RXC Turbo and cranked it to about 12 or 13 by boosting its 3.5-liter EcoBoost’s output to 530 horsepower, which is a 76-horsepower jump. Torque, on the other hand, falls from 500 pound-feet to 481 pound-feet for some unexplained reason. This insane amount of power results in a 0-to-100-mph time of 6.8 seconds and a 40-to-80-mph time of just three seconds, which is best in the class.

The power bump is courtesy of a pile of new parts, including a pair of new high-performance, water-cooled Garrett GT28 turbos; Owen Developments twin-phase anodized actuators; a revised, fluid-optimized intake manifold; high-performance Ford injectors; a fuel rail upgrade with an improved flow rate; a race-ready fuel regulator; high-flow, Ni-resistant alloy manifolds; a larger-diameter exhaust system; and a LIFE engine management system.

Delivering the goods to the rear wheels is an RPE/Quaife seven-speed transverse gearbox with paddle shifters. This transmission rams through the upshifts in 50 milliseconds, and auto throttle blips make for easy clutchless downshifts. Out back is a Quaife Automatic Torque Biasing differential for ideal traction in the corners.

Drivetrain Specifications

Type 3.5-liter EcoBoost V-6
Output 530 HP @ 6,100 RPM
Torque 481 LB-FT @ 5,000 RPM
0-100mph 6.8 seconds
40-80mph 3.0 seconds

Suspension and Brakes

I am assuming that the RXC Turbo 500 carries the same underpinnings as the RXC Turbo, which includes an Intrax Racing Suspension inboard-pushrod system with double wishbones at all four corners. The dampers are fully adjustable for varying road conditions.

The brakes comprise 350 mm front and 310 mm rear floating rotors clamped by six-piston calipers. As an option, buyers can swap out the metallic rotors for a set of carbon-ceramic units that not only reduce unsprung weight, but also reduce brake fade.

17-inch, center-lock rollers round out the keep-it-on-the-track bits.


Radical didn’t go into pricing, but we already know that the RXC Turbo runs £107,500 ($164,975 as of 2/17/15) (VAT excl.), so I wouldn’t be shocked to learn that this upgrade to the 500 tacks on an extra £20,000 ($30,693 as of 2/17/15) to £30,000 ($46,039 as of 2/17/15).

According to the press release, this kit is available to order now, but there is no mention of it on the Radical website.


Ariel Atom 3.5R

There aren’t too many cars that can really compete with the RXC Turbo 500, but the Ariel Atom is one that may give it a run on the track. In its base setup, which produces just 245 horsepower, the Atom has no hope, but bumping up to the 350-horsepower 3.5R model may do the trick.

Thanks to this super-powerful 2.0-liter i-VTEC powerplant and a Sadev six-speed transmission that upshifts in 40 milliseconds and downshifts in 50 milliseconds, this open-air two-seater can hit 60 mph in just 2.6 seconds.

The only downside to the Atom is that you’re stuck with no roof. Where the Atom 3.5R wins is in terms of pricing, as it runs just £54,000 ($82,903 as of 2/17/15).


There’s nothing like making a good thing better, and that is precisely what Radical is doing with the RXC Turbo 500. With a 530-horse 3.5-liter EcoBoost, there is little that can hang with it – million-dollar hypercars included. Sure, it is just barely a road-ready car by most standards, but all of that glorious speed more than makes up for it.

    • Very expensive
    • Not many luxuries to speak of

Press Release

UK extreme road and track car manufacturer Radical Sportscars will mark its debut appearance at the Geneva Motor Show on 03-15 March by unveiling the RXC Turbo 500, a 530bhp variant of its road coupe. The RXC Turbo 500 takes the RXC’s performance into true hypercar territory – and to prove this the marque will be returning to the famed Nürburgring Nordschleife for a new assault on the production car lap record in August.
The RXC Turbo 500 is the culmination of five years’ development to create a road-legal track car unlike any other. The latest engine management and forced induction technology has been utilised to raise the performance bar even higher, with the new model delivering over 530bhp at 6,100rpm and an incredible 481lbft at 5,000rpm, endowing the car with a power-to-weight ratio of over 462bhp per tonne – well in excess of established supercar models.

In-gear acceleration and response improves dramatically as a result, with an RXC now accelerating from 0-100mph in just 6.8 seconds, and mid-range acceleration from 40-80mph in a class-leading 3.0 seconds. Coupling this astounding performance with Radical’s trademark lightweight, high-stiffness chassis technology and advanced Le Mans-honed aerodynamics, has resulted in a road car with performance capabilities that exceed those of dedicated racing cars.

The RXC Turbo 500 upgrade package includes:

> Twin high-performance water-cooled Garrett GT28 turbochargers fitted with steel ball bearing cartridges, and specially designed anti-surge compressor housings

> Owen Developments twin-phase anodised actuators for precise boost control

> New custom-designed heat shields fitted to reduce engine bay temperatures

> Re-machined, fluid optimised intake manifold upgraded to contain six high-performance Ford fuel injectors. The addition of these allows for performance staged, secondary port injection that improves fuel atomisation at higher engine speeds with increased flow rates – a system developed by Radical and now adopted on Ford’s high-performance Ford GT concept

> Twin additional fuel rail upgrade with new motorsport fuel lines

>Upgraded race proven fuel regulator

> New high-flow Ni-Resist alloy exhaust manifolds designed to improve the exhaust flow rate, providing maximum turbine speeds, reduced spool time and improving top end performance

> New large-diameter motorsport-specification exhaust system, with improved flow rate

> LIFE engine management system mapping upgrade optimised to the increased power output for ultimate performance and drivability

Radical’s founder and Managing Director Phil Abbott is delighted with the results. “Our outstanding technical team wanted to deliver something really special in the RXC Turbo 500, and I think they’ve definitely moved the game on.

“The partnership between the RXC’s accessible aerodynamics and grip, and the ballistic performance of the Turbo 500’s high-performance Ford EcoBoost powerplant delivers an intoxicating, spectacular driving experience like no other road car.”

Full European Type Approval has now been achieved for the RXC Turbo after a year of certification including crash testing, emissions and noise assessment. The RXC Turbo can be road registered in any European Community (EC) member state as well as a host of other countries worldwide.

RXC Turbo 500 aims to extend Radical’s ten-year-long reign at the Nürburgring

To showcase the speed, grip, balance and exploitability of the new package, Radical will be returning to the Nürburgring Nordschleife road course in Germany this August, for an attempt to beat its own, long-standing production car lap record. The company’s SR8 LM open sportscar has held the record since 2005, first with a 6m55s lap then lowered to 6m48s by Michael Vergers in 2009. Radical will follow the same transparent procedure as before, driving the record car the 480-mile journey from its Peterborough, UK headquarters to the circuit nestled high in the Eifel Mountains of Germany.

There will be three record runs. The car will wear Dunlop SportMaxx road tyres for the first run on the gruelling 20.8km, 154-km course - the same tyres on which it arrives from the UK. The team will then switch to the Dunlop Direzza D03G road-legal performance tyre, as used for Radical’s previous successful record attempt. Finally the Dunlop SP Sport slick tyre will be used, highlighting the adaptability and easy adjustment of the RXC Turbo 500 and the broad ability of the Dunlop performance tyre range.

Upgrade package available to order now

The RXC Turbo 500 upgrade package is available to order now, for road registration throughout the EC as well as other countries worldwide. Distributor demonstrators are being delivered now for test drives – to find out more visit the Radical Global website at
