The TVR Tuscan Challenge is a one-make series dedicated to the second incarnation of the TVR Tuscan sports car (developed specifically for the series), and takes place throughout the United Kingdom. Inaugurated in 1989, its high power-to-weight ratio, capability of reaching convert|190|mi/h|km/h|-1|abbr=on and loud engine noise, combined with close racing in a field consisting of over 30 cars at its peak, made the series become, at the time, the premier one-make series in the UK with an extensive TV coverage; over the years, many drivers who competed in the series moved on in major championship series and many notable drivers have guest driven in a race. The company underwent management changes in 2005, and the TVR Tuscan Challenge was merged with its owner club's series, which has been reformatted to allow for all TVR models.

This version of the Tuscan is not to be confused with either the earlier V8/6 model or the later roadgoing Speed 6 version.

History

With the success of the S Series, TVR began development of an ES, [http://www.tvr-car-club.co.uk/about_tvr.asp TVR Car Club, About TVR: Past and Present] ] an S series sports car with a Holden V6 3.8 litre engine. [http://www.pistonheads.com/tvr/tuscanracer/history.htm Tuscan Racer History] ] It wasn't until the 1988 British Motorshow, in Birmingham NEC; the car was unveiled as a prototype with plans for it to be developed for road use, [http://www.glynnsport.co.uk/tvrchallenge.htm Glynnsport :: The TVR Challenge Series] ] but in order to attract public interests and stimulate sales, TVR resurrected the Tuscan name and at the same time instigated the one-make TVR Tuscan Challenge series.

In order to attract a large field, TVR offered the first batch at a discount of £16,000 plus VAT for entrants with a condition that they commit themselves to compete at least six of the twelve races in the championship. Should that fail, the purchaser would agree to pay the extra £16,000 at the end of the season.

With the instant success of the series in its first year in 1989, plans for a road car fell by the wayside as TVR was busy with the 'S' and the older wedge models as well as design and development work for the forthcoming Griffith and Chimaera models.

It never went beyond the motor show prototype stage, and the Tuscans continued to be produced in small volumes as racing cars. [http://www.pistonheads.com/roadtests/doc.asp?c=107&i=10750 PetrolTed reports on Shane Antill's road-legal TVR Tuscan] ]

The S based chassis had to be developed to cope with the extreme power outputs of the tuned Rover V8 engine; by the end of its development, it ended up being a completely new chassis with a wider track, increased wheelbase and much strengthening.

Its original output was 350 bhp (261 kW) sourced from the TVR 350i that was transmitted through a Borg Warner T5 gearbox to its nine inch (229 mm) wide wheels. In the early 1990s, as the aging Rover V8 was getting beyond its development limits and Rover's takeover by BMW, plus his rumoured refusal of having German engines in his cars, Wheeler commissioned engine designer Al Melling to develop the new AJP8 engine, producing more power than its Rover counterpart. With the new V8 engine, the car was capable of 0-60 mph in over 3 seconds and 0-100 mph in just 6.9 seconds. The cars boasted of convert|536|bhp|abbr=on per tonne (400 W/kg) with a capability reaching in excess of convert|190|mi/h|km/h|-1|abbr=on, the cars became popular with race goers. All engines are factory supplied sealed units to ensure a level playing field. [http://www.tvrbliss.co.uk/andyholdenracing/the-cars.asp Andy Holden Racing] ]

Dealers were usually encouraged to enter the series [ [http://www.guglielmimotorsport.co.uk/steveguglielmi.html Guglielmi Motorsport Ltd.: Introducing Steve GUGLIELMI] ] and the then company owner Peter Wheeler competed in the series, from which he used his expertise to develop the Speed 12, its managing director at the time, Ben Samuelson also competed in the series. Many drivers who are now competing in the Le Mans Series, FIA GT Championship and 24 Hours of Le Mans, such as Jamie Campbell-Walter, Bobby Verdon-Roe, Martin Short and Michael Caine, developed their skills in the series. [http://www.jnjmotorsport.com/tvr.htm jnjmotorsport.com ] ] Nigel Mansell was to compete for a one off race at Donington Park in 1993 but was unable to after he was hospitalised following a BTCC incident. [http://www.third-place.com/sub/cerberav8racing/series.htm cerberaV8racing.co.uk - campaigning the Dunlop Tuscan Challenge Series 2007] ] Other drivers who have guest driven in the series throughout its history includes Colin McRae, Andy Wallace, Tim Harvey, Anthony Reid, Tiff Needell and John Cleland.

Carlube sponsored the series between 2002 to 2004. [ [http://www.carlube.co.uk/index.cfm?page=74 Carlube Motor Oil & Automotive Lubricants - - About Carlube Motor Oil] ] The series was now renamed Dunlop TVR Challenge. At the end of 2003, a version of the T350 known as the Sagaris was introduced with an intention to run alongside the racing Tuscan and to eventually replace them. But when owner Peter Wheeler sold the company to Nikolay Smolensky, who abruptly ended factory support before the 2005 season had begun. TVR's Motorsport Director acquired the rights and kept the series going but on a much smaller basis; by then, TVR had sold off all its racers. [ [http://www.hawthornsmotorsport.co.uk/ Hawthorns Motorsport] ] With waning entries as many of these cars had either been converted to road use or ended up in track days, the series would continue under a new format as it merged with the Toolsnstuff.co.uk/SIP TVRCC Challenge Cup, a smaller series that consists of a wide range of TVR models, meaning that the gird now featured a more diverse range of TVR models in one race and the series split into three categories "(see Categories)".

In 2006, the series acquired a new sponsor, Dunlop Tyres, which meant it provides the tyres, giving a leeway for drivers to decide if they want to compete on slicks, road or track tyres and not just restricted to TVR's; the series has an Invitation Class for any make of sports car providing that it complies with the MSA regulations for the original championship it was built to race in. [ [http://www.brscc.co.uk/tuscan.html BRSCC - Tuscan ] ]

Many of these models have found their way competing outside the series, and some of them have been converted in to a Sagaris clone as they share similar parts and are the same dimensions. Driver Michel Mora used a Tuscan Challenge in the FFSA GT Championship from 1999 to 2001, before being joined by a second car from Massimo Cairati. Cairati also ran his car in select rounds of the Italian GT Championship that year, finishing ninth in the overall drivers championship and second in his class.

Due to the Tuscan Challenge's participation in national grand tourer series in the 1990s, the cars were made eligible for the GT90s Revival Series, a historic racing series. [ [http://www.gt90s-revival.com/docs/GT90s_Eligible_cars.pdf GT90's Revival Series - Eligible Cars] ] Two Tuscan Challenges raced at the series' first round at Silverstone. [ [http://www.gt90s-revival.com/docs/Silverstone_Results.pdf Microsoft Word - 02 Silverstone Front Pages.doc ] ]

Categories

In the series, the depending on the engine capacity and power output, the series are split into three categories.
* Class A - Turbo cars up to 3.0 litres and more than 350 bhp (261 kW), normally aspirated cars with 5.0 litres or more than 350 bhp (261 kW). Consists of the AJPV8 powered Tuscans and the racing Sagaris's.
* Class B - Turbo cars up to 3.0 litres with less than 350 bhp (261 kW), normally aspirated cars between 3.0-5.0 litres and less than 350 bhp (261 kW).
* Class C - Normally aspirated cars up to 3.0 litres. Only the modified 4 or 6 cylinder and standard Rover V8 engine are eligible.

Road going versions

Despite never produced for road use as originally intended, owners have converted the Tuscan race cars for road use as they share the same space frame chassis and build principles of its road going sister models without the level of comfort and trim quality. The majority of these are converted racing cars and fewer have built them from scratch, just by sourcing the chassis and bodywork and adding the level of comfort to suit their needs.

Conversions includes installation of a speedometer (as racing cars do not have them), changes to the lighting system, having the chassis powder-coated, relocating the fuel tank from the original driver's side to the rear of the car to allow for a passenger seat and conversions to protect the fuel cell in an event of an accident. Also installation of traction control is considered to be an option. [http://www.pistonheads.com/tvr/tuscanracer/conversion.htm TVR Tuscan Road Legal Conversion] ] However obtaining the car plus the prohibitive cost of conversion at £10,000 and the complication of the task makes finding such a model on a public road a rare find.

Many of the converted Tuscans which house the AJP8 engines have engines that are commonly sourced from accident damaged Cerberas as race engines are leased by the factories, though its Rover V8s of the earlier cars can be easily sourced.
