MINI COOPER S WORKS GP (R53)
A genuine road-going special – in miniature
LESS PRACTICAL, MORE EXPENSIVE AND WITH A minimal increase in power over the model it evolved from, the original Mini GP could have been a tough sell at launch. As one of the very first hardcore hot hatches, many had their reservations about the concept, but it all made sense behind the wheel: the claims by BMW/MINI bosses that it could be seen as ‘a baby M car’ or ‘maybe even a junior CSL’ proved to be not far from the truth.
Under the bonnet was the same supercharged Tritec 1.6-litre four-cylinder as found in the Cooper S and S Works, but with its Eaton M45 supercharger faster spinning, a revised intake system improving flow, and the likes of uprated injectors, a more efficient intercooler and a less restrictive exhaust system contributing to better response and longevity. These changes liberated 218bhp in total, which was just 8bhp up on the S Works, but the real effort had gone into the chassis upgrades and weight reduction measures that made the GP a true no-compromises offering.
Some 50kg was trimmed from the kerb weight compared with the Cooper S Works, taking the GP down to just 1090kg. This was achieved by swapping the rear seats for a strut brace, developing bespoke aluminium control arms for the rear suspension (a 15kg saving alone), fitting lightweight 18-inch wheels (for a 2kg saving per corner), and removing sound deadening material, the air conditioning and the rear-screen wash/wipe.
The front splitter, muscular side sills and carbonfibre roof spoiler were all bespoke for the GP, while a 10mm ride height drop improved the stance, with stiffer springs and tighter damping boosting agility. The sole colour option was Thunder Grey.
Direct, quick-ratio steering and that trademark lively Mini feel make themselves known even at low speeds, but up the pace and the GP comes into its own. Torque is strong from its uprated four-cylinder, composure and grip are excellent, and its small dimensions make it a perfect match for Britain’s roads.
Due to its bespoke construction, the GP was manufactured by Bertone in Italy, with 2000 units produced in total (each car had its unique number emblazoned on the roof). Some 459 made it to the UK, demand proving stronger than anticipated. Today prices start at £12,000 for cars with 120,000 miles or more. In the region of £15,000 gets a tidy example on around 50,000 miles, with the finest, lowest-mileage cars costing closer to £18,000.
Reliability is strong overall. Check for previous maintenance on the supercharger and power steering system, as these can be the most costly to fix – some specialists suggest that the former has a lifespan of around 100,000 miles, which is something to bear in mind. Any Gp-specific parts are likely to be pricey (decals included), so ensure the condition of these is to your liking before purchase or that the price reflects any work required.
