Alongside the stylish Corsa city car, the UK's most popular medium sized car, the Insignia, now gets an automatic option for the sporting VXR and at the top of the range a new 'halo' model VXR GTS provides something to look up to.With just 30 cars to sell with the GTS badge, this is going to be a very exclusive model over and above that of the VXR Clubsport, which is more widely available.Four years after it first appeared on UK roads, Vauxhall's storming VXR8 GTS model is back with heavily revised front and rear-end styling, a new cabin and new technology under the eye-catching skin.Priced at £49,500, the new VXR8 is based on HSV's E3 GTS model and the previous VXR8 remains as the lower-spec ClubSport R8 at £45,000.That means it still undercuts full-size super saloons like the Audi RS6, Jaguar XFR and Mercedes E63 AMG by between £13k and £29k, and even performance saloons from the segment below, such as the BMW M3 and Mercedes C63 AMG.The latest GTS has what Vauxhall call a 'Shockwave' grille, LED daytime running lights and sleek new wing-vents at the front, while the rear features a new large 'Superflow' rear spoiler, LED tail lamps and twin exhaust tips that mimic the shape of the front grille.The fourth generation 6.2-litre LS3 unit produces 431PS and a massive 550Nm of torque, enough to propel the VXR8 from 0-60mph in 4.9 seconds and on to a governed top speed of 155mph. Drive is delivered to the rear axle via either a new MM10 six-speed manual gearbox with uprated LS7 clutch, or a six-speed auto 'box.It now comes with magnetic dampers and launch control to sharpen responses and offer drivers a choice of refining their driving style between performance or track settings.Inside, drivers and passengers have full leather trim and front occupants are cocooned in special HSV Performance Seats with eight-way electric and manual adjustability.A new instrument cluster and surround, centre stack and switchgear also includes aux/USB inputs, iPod support and Bluetooth with phone book display and touch-screen dialling.Vauxhall has introduced EDI, or Enhanced Driver Interface. EDI connects with the on-board computer to constantly stream real-time vehicle dynamics and performance to the car's main 5-inch monitor.At the touch of the screen, drivers can access a variety of data such as vehicle G-forces, power and torque and lap times - even the angle their VXR8 is drifting.Completing the clever package is the ability for drivers to download data, such as track day performance, and analyse it using the MOTEC i2 software provided.There will be two more variants in the near future, the Maloo pickup and the Sports Tourer at £47,000. Vauxhall Insignia VXRVauxhall's most powerful Insignia model, the 325PS VXR, is now available with an intelligent six-speed automatic gearbox, which does not detract from its 155mph maximum speed or 0-62mph time of about 6secs.The Insignia VX R Auto allows enthusiastic drivers the choice of full control over gear selection, or the convenience of a fully automatic mode on less demanding roads.The new automatic 'box is fully adaptive and is connected to the Insignia VXR's standard four-wheel-drive FlexRide chassis, which automatically responds to changing road conditions and driving styles.Drivers choose between a default 'standard' mode ideal for everyday driving, or 'sport' mode, which stiffens the car's dampers and reduces body movement at higher speeds.In addition, a separate VXR button sharpens the car's steering and throttle response, as well as firming up the dampers still further. And in case that wasn't enough, all the dials glow red too.The VXR Automatic's gear-shifting character also automatically adapts to prevailing road/driving inputs and it learns the driver's style and preferences to optimize performance and economy. Vauxhall Insignia VXR first driveThe refinement of the Insignia VXR automatic is exceptional and it loses nothing in driver appeal because you can leave it to its own devices or make sequential changes up and down without any hesitation or roughness.Responses are sharp, the ride composed and comfortable and it is arguably the best Insignia in the line-up. I saw just over 22mpg. Vauxhall VXR GTs first driveIf you love muscle cars, then flex your wallet for the VXR GTS. It packs a heck of a punch when given its head but this close-cropped competition-wannabe does not come with a bone-breaking ride even in the track setting.Push the button for the performance mode and it is slightly more compliant if not quite as edgy, but you'd hardly see any deterioration on country roads.Room is excellent, the half-electric front seats are figure hugging and surprisingly comfortable, working well with the multi-adjustable column to give any desired driving position.Over a comparatively short distance I saw it return 17mpg, which puts it into the super-car league but if you include the fact it will seat five, that makes it more economical per occupant than many high performance and less practical two-seaters.Those with long enough memories might compare it to the famous and iconic Lotus Carlton. The VXR GTS is expensive for a Vauxhall, but it's cheap for the supercar it is.
