Two new Hyundai concepts and one new production model will make their debut at The Sunday Times Motor Show Live starting tomorrow.

The Tucson (pronounced Too-son) is Hyundai’s entry-level 4×4 and sits below the existing Santa Fe and Terracan. The Tucson is designed to compete against cars such as the Toyota RAV4, Honda CR-V, Subaru Forester, Mitsubishi Outlander and Kia Sorento.

The Tucson has a monocoque construction, based on a modified version of the current Coupe platform.  There will be three engine options offered (2.0-litre 134bhp petrol, 2.0-litre 110bhp common rail turbo diesel, and a 2.7-litre 173bhp V6), and two trim levels; GSI and CDX. Transmissions are five speed manual or four speed auto, with a ‘torque-on-demand’ 4×4 system that powers the front wheels during normal driving, transferring power to the rear when it detects a loss of traction. Permanent 4×4 can be selected at speeds up to 19mph.

All models will feature driver and passenger airbags, ABS with EBD, traction control, front fog lights, electric tilt and slide sunroof, roof bars, electric windows and door mirrors, and RDS radio/CD player.

Prices will start at around £15,000 and all models come with Hyundai’s five year unlimited mileage warranty.

Hyundai’s HCD8 sports prototype will make its first UK appearance at the show.

The HCD8, unveiled at the Detroit Motor Show earlier this year, is said to give a ‘strong indication for future Coupe design direction.’

The car is the first to come from Hyundai’s new $30 million Design and Technical Center in California, and has been designed to offer a combination of sporting intent and practicality.

Joel Piaskowski, Chief Designer at the Hyundai Design and Technical Center, said: “The Hyundai HCD8 sports tourer was designed to address the sporty car market and still meet the values and needs of today’s consumer. It is designed to be a high-performance car for everyday use. We also stayed true to the core Hyundai asset of making it outstanding value.”

The interior features wood flooring, two-tone leather seats, wood and aluminium-trimmed steering wheel and gearshift knob.

Powered by a supercharged 2.7-litre V6 engine driving a 6-speed manual trans-axle, air suspension allows the driver to adjust the ride height by four inches.

Also making its first UK appearance is the Hyundai CCS.

Unveiled at last autumn’s Frankfurt Motor Show, Hyundai is currently preparing the car for production following a positive reception, with plans for introduction by 2007.

The CCS (Coupe Cabriolet Study) is the work of Hyundai’s Frankfurt-based Research and Development Centre and convertible specialists Karmann, and is based on Hyundai’s Coupe 2+2.

The car features a three-phase slide-and-fold roof – at the touch of a button the driver can switch from a glass roof, to an open roof to a full convertible. If the weather is changeable, the driver can retract the glass sliding roof back over the rear window (by going over the rear window, headroom is not compromised) – the side supports remain in place so should the weather change, the roof can slide back quickly into position.  Changing to a full convertible requires the press of a second button which folds in the rear screen, and retracts the roof in a way that still gives maximum luggage space.

The folding roof system is an advance over previous convertible systems as it requires fewer pivot points, and weight increases only by 140kg. Hyundai believes solar panels could easily be worked into the structure of the CCS roof design in the future.

The exterior look has been sharpened over the Coupe, with 18-inch wheels and new front and rear light clusters, while interior sprucing includes the fitment of leather Recaro seats and a 280W Becker/Infinity stereo system. Boot capacity is 443 litres with the roof closed, 244 litres with it folded.

The CCS uses a 2.7-litre 165bhp V6, driving a six-speed Aichi gearbox.
