An Eaton supercharger, 6.2-litre V8 driving the rear wheels, nearly 600bhp and a soundtrack guaranteed to make your hairs stand on end: welcome Vauxhall’s new VXR8 GTS, which can be ordered from today with first deliveries at the end of the year.
Based on sister company HSV’s new GEN-F GTS, the VXR8 GTS is the most powerful production car ever to emerge from Australia. And with an on the road price of just £54,999 in the UK it allows owners the least expensive membership into the 500bhp+ club.
‘The very fact that cars like the VXR8 GTS still exist proves that there is a small, but immensely passionate band of customers out there who want to drive something which is unique and special,’ said Stuart Harris, Vauxhall’s Head of Carline Brand. ‘In its new GTS form the VXR8 offers colossal power and torque in a package that is more technology-led than ever before, yet still retains that unique VXR8-character that no BMW or Mercedes can match. It’s also around £20k less than its main rivals – the M5 and E63 AMG – yet has more power than either.’
Engine
At the heart of the VXR8 GTS is a new supercharged LSA V8 (identical to that used in the recently launched Chevrolet Camaro ZL1), delivering 576bhp and 545lb ft of torque, an increase of 150bhp and 140lb ft respectively over the outgoing, LS3-engined VXR8. Performance figures will be released soon, but bear in mind that even the naturally-aspirated VXR8 achieved a 0-60mph time in 4.9 seconds and a limited top speed of 155mph…
The new VXR8’s Eaton supercharger has 4-lobe rotors, 9psi boost and 1.9 litres of air per revolution. Unlike a turbocharged car, the Eaton supercharger provides the VXR8 with stronger and more linear performance across its entire rev-range. Other LSA features include:
- Stand-alone water to air charge cooling system
- Separate transmission and differential cooling system
- Water to oil engine cooling system
- Bi-modal air-intake system
- High-flow exhaust manifolds and exhaust system with Bi-modal silencers
Delivering drive to the rear axle is the latest MG9 spec 6-speed manual transmission with oil cooler and twin-plate clutch (an optional 6-speed automatic transmission is also available).
Design
The new front-end design of the VXR8 GTS has bold graphics and shallow ramp angles that emphasise width and stance. The focal point of the new look is a ‘twin-nostril’ grille and an all-new fascia that helps to deliver both an aggressive look and an air intake surface large enough to cool the LSA V8.
In fact, a total of 130,000 square millimetres of open frontal surface was needed to deliver the cooling required for the new engine – 75 per cent more than the outgoing LS3-engined car.
Daytime running lights – which can now operate when the headlights are turned on – and 20-inch ‘Blade’ forged alloy wheels complete the front-end design.
At the rear, the VXR8 GTS has distinctive LED tail lamps, while the ‘diffuser’ rear fascia houses quad exhaust outlets finished in shadow chrome. A unique body-coloured performance rear spoiler with black accents helps set the GTS apart still further.
Inside, the VXR8’s cabin design has undergone a raft of design changes. An upgraded instrument panel with suede-style inserts, a new instrument cluster, gauges, centre console, appliques and door trims combine to deliver a more premium look and feel.
Standard in the VXR8 GTS, all-new VXR Performance Seats are wrapped in Onyx leather trim and feature 8-way electric adjustment and seat heaters for both the driver and front passenger.
Dynamics
To cater for the extra performance offered by the LSA engine, the VXR8 GTS is fitted with an all-new Brake Torque Vectoring technology. Brake Torque Vectoring helps reduce understeer by generating a ‘rotational moment’ in the rear axle while the car is under power. The Electronic Stability Control (ESC) system detects the understeer, applies braking to the inside rear wheel and transfers torque to the outside rear wheel, preventing the front end from washing wide.
The VXR8 GTS also receives third-generation Magnetic Ride Control (MRC) with three independent settings: Touring, Sport and Track. Hardware and software improvements combine to deliver greater body control, sharper handling and a significantly more pliant ride quality, compared with the outgoing model.
Wider tyres also offer drivers more grip. Continental 255/35 R20 (front) and 275/35 R20 (rear) were chosen as standard equipment, due to their exceptional performance in both wet and dry conditions.
To assist drivers in manipulating the various electronic vehicle performance systems, a new Driver Preference Dial has been developed. Located behind the gear lever, the Driver Preference Dial adjusts settings to one of four modes: Touring, Sport, Performance and Track. The vehicle’s ESC, Traction Control, Launch Control (manual transmission only), and Bi-Modal Exhaust, as well as its Brake Torque Vectoring and new Electronic Power Steering, are then adjusted accordingly.
The VXR8 GTS’s braking capacity has been dramatically increased with the fitment of AP forged 6-piston calipers with two-piece discs front and rear. Combined with the increased disc diameters, the calipers – forged from 6061 T6 aluminium – offer a vastly improved strength-to-weight ratio and deliver noticeable improvements in brake modulation and feel. The rear brake pad size has also been increased by 12 per cent.
‘With our new forged calipers, larger rotors and increased pad size, we’re confident that the GTS brake package is the equal of anything in the world,’ said HSV’s Chief Engineer, Joel Stoddart.
Technology
The VXR8 has now come of age, and features an array of technologies never seen before in this model.
In addition to the Side Blind Zone Alert with Reverse Traffic Alert, Automatic Park Assist, Front and Rear Park Assist, Reversing Camera and Passive Entry/Push Button Start, the GTS also picks up a number of additional driver convenience and safety technologies.
Head Up Display is standard and shows a raft of driver information on the windscreen, such as vehicle speed, engine temperature, and even G-forces!
Forward Collision Alert is another technology fitted standard to the GTS, and is the first system of its kind to be available in a Vauxhall product. A camera, located above the rear-view mirror scans the road ahead up to 14 times per second. When a crash is predicted, the driver is alerted with an audible tone and a visible alert on the car’s HUD. Anticipating hard braking, the system applies sufficient brake pressure to close the space between the brake pads and discs, thus delivering a quicker brake response time.
Using the same camera technology, the VXR8 GTS also has Lane Departure Warning. Designed to combat driver fatigue, a warning indicator and audible sound alerts the driver to any unintentional lane departures
MAGNERIDE DAMPERS ON NEW VAUXHALL VXR8 GTS
High spec model uses latest BWI technology to deliver uncompromised ride and handling
The Vauxhall VXR8 GTS will use third-generation MagneRide suspension from BWI Group to combine trackday handling with road-car comfort, when it goes on sale later this year. The impressive new supersaloon, developed by Australian firm Holden Special Vehicles and sold in the UK as a Vauxhall, has a maximum power of 577bhp (430kW), peak torque of 740Nm, and employs BWI’s MagneRide in its Magnetic Ride Control system.
“Traditional suspension systems have to compromise between ride quality, road holding and body control,” said Alex Shnaider, the project’s lead development engineer and BWI’s Country Manager for Australia. “MagneRide overcomes this restriction, providing a comfortable everyday ride, precise body control for enjoyable handling on the track and real-time management of the tyre loads to make best use of all the available grip. The MRC system on the VXR8 is the latest edition of a well established relationship between HSV and BWI’s magneride, which has previously been seen on the HSV Senator and HSV Grange. ”
The key to MagneRide suspension is the Magneto Rheological (MR) damper fluid which contains tiny iron particles that can be quickly but temporarily magnetised by energising electrical coils in the damper piston. When the current is off, the particles are randomly dispersed and the damper is in its softest setting. Applying a current magnetises the particles, which then attract each other, in proportion to the strength of the magnetic field, increasing the resistance to flow and stiffening the damping. The result is an ability to vary the damping force almost instantaneously over a wide range, just by varying the current applied.
The latest generation, twin-wire dual-coil (TWDC) MagneRide units adjust their damping 1000 times per second to provide the optimum control and response, whatever the driving conditions. In the TWDC system the previous single electrical coil in each damper has been replaced by two smaller coils, providing quicker ‘current-off’ performance, to give the new system a faster transient response. The new dual-coil architecture also contributes to providing an extended dynamic range (a ‘softer soft’ and a ‘harder hard’) that is able to cope with the extremes of trackday driving without compromising the ride during normal use.
In addition to the system’s self-acting capability, drivers can select between Touring, Sport and Track settings using a Driver Preference Dial that also controls other aspects of the car, such as the exhaust note, steering calibration and traction control settings.
“The VXR8 GTS has a supercharged 6.2L V-8 with almost 580 horsepower, but balanced handling, comfort and safety were as important as straight line performance,” said Schnaider. “With MagneRide suspension, we were able to deliver precise control to suit the most enthusiastic track use, and the comfort for everyday driving.”

VAUXHALL’S NEW SUPERCHARGED VXR8 GTS SET FOR DEBUT AT AUTOSPORT SHOW
With an extra 150bhp from its new supercharged engine, class-leading chassis technology and a price that will make its closest rivals wince, Vauxhall’s new VXR8 GTS is set to make a surprise debut at the Performance Car Show alongside Autosport International next month.
Based on Vauxhall’s sister company HSV’s new GEN-F GTS, the VXR8 GTS is the most powerful production car ever to emerge from Australia. And costing just £54,999 in the UK it allows owners the least expensive membership into the 500bhp+ club.
‘The Performance Car Show and Autosport International is an ideal location for us to take the wraps off the UK’s first new VXR8 GTS,’ said Stuart Harris, Head of Carline Brand. ‘While this is unashamedly one of the most powerful road cars you can buy in the UK, the GTS was developed by people who have a wealth of experience in motorsport, so putting it in front of thousands of car racing enthusiasts is a no-brainer for Vauxhall.’
In its new GTS form the VXR8 offers colossal power and torque in a package that is more technology-led than ever before, yet still retains a ‘loud and proud’ character that no BMW or Mercedes can match. It also enters the UK market with more power than key rivals, such as the BMW M5 and Mercedes-Benz E63 AMG.
At the heart of the VXR8 GTS is a new supercharged LSA V8 delivering 576bhp and 545lb ft of torque, an increase of 150bhp and 140lb ft respectively over the outgoing, LS3-engined VXR8. The mighty powerplant will allow the GTS to sprint from 0-60mph in 4.2 seconds and up to a limited top speed of 155mph.
To cater for the extra performance, the GTS is fitted with an all-new Brake-Torque Vectoring system that applies braking to the inside rear wheel and transfers torque to the outside rear wheel to reduce understeer during high-speed manoeuvres.
The GTS also receives the latest generation Magnetic Ride Control with three independent settings. Hardware and software improvements deliver greater body control, sharper handling and a significantly more pliant ride quality, compared with the outgoing model.
‘In an Ashes year, it’s quite rare to see England and Australia working together, but the result of this collaboration in the new Vauxhall VXR8 GTS is amazing,’ said Ian France, Performance Car Show Director. ‘With almost 600bhp of raw power and imposing styling, it’s sure to create a lot of interest as part of Vauxhall’s Performance Car Show presence.’
The Performance Car Show will run from January 9-12 (9th & 10th are trade days only) as part of the Autosport International Show at Birmingham’s NEC.
