When Malaysian motorsport fans think of Proton in the British Touring Car Championship (BTCC), the iconic Petronas Syntium Proton (PSP) Impian/Waja from 2002 to 2004 usually steals the spotlight. Yet nearly a decade later, another Malaysian sedan returned to Britain’s premier touring car grid—not as a factory-backed works entry, but as an ambitious privateer project.
Between 2011 and 2016, independent British outfit Welch Motorsport designed, built, and campaigned the Proton Persona (known in Malaysia as the Proton Gen-2) under the BTCC’s Next Generation Touring Car (NGTC) regulations.
From Road Car to Widebody NGTC Contender
Founded by veteran racer John Welch and led on track by his son Dan Welch, Welch Motorsport took advantage of the BTCC’s new-for-2011 NGTC ruleset, which aimed to lower costs by allowing independent teams to build race cars around standard road-going bodyshells paired with standardized subframes, suspension components, and a 2.0-liter turbocharged engine formula.
While Malaysia’s showroom Persona/Gen-2 was powered by the 1.6-liter CamPro engine, the BTCC challenger was an entirely different beast:
- Engine: A 2.0-liter turbocharged direct-injection four-cylinder engine built to TOCA/Swindon Powertrain NGTC specifications (producing 300+ hp in official race trim, and capable of 400+ hp unrestricted). (Note: During the 2014–2015 seasons, Welch Motorsport also experimented with developing its own in-house NGTC powerplant before returning to the proven TOCA unit.)
- Transmission & Drivetrain: Front-wheel drive (FWD) mated to an Xtrac 6-speed sequential racing gearbox and AP Racing carbon clutch.
- Electronics: Full Cosworth Electronics ECU, dash display, and data logging system.
- Chassis & Aero: Custom widebody arches, aggressive front splitter, flat floor, and the series-mandated NGTC carbon rear wing.
Six Seasons of Iconic Liveries (2011–2016)
Across six seasons of hard-fought touring car action at circuits like Brands Hatch, Oulton Park, Silverstone, and Donington Park, the Welch Motorsport Proton Personas wore several memorable liveries:
- 2011–2012: #42 Dan Welch (Marriott)
Debuting mid-season at Snetterton in 2011, Dan Welch’s #42 Persona initially ran a clean white base before adopting its signature maroon, grey, and white Marriott sponsorship scheme—an instant fan favorite. - 2013: #10 Dan Welch (sopp+sopp / FleetWatch)
Switching to #10 for 2013, the Persona adopted a sharp white and royal blue livery backed by vehicle accident management firm sopp+sopp and FleetWatch. - 2014: #48 Ollie Jackson & #13 Dan Welch (STP / Quai)
Welch Motorsport expanded to a two-car Proton lineup in 2014. Ollie Jackson piloted the #48 car carrying classic STP and Quai branding, while Dan Welch ran the #13 sister car in a striking yellow, blue, and white Quai Administration Services design. - 2015: #12 Andy Wilmot (Boxo Tools) & #13 Dan Welch (Quai)
Alongside Dan Welch’s returning #13 Quai machine, Andy Wilmot joined the squad in the #12 Persona dressed in a vibrant white, teal, magenta, and navy Boxo-Tools.co.uk livery. - 2016: #17 Dan Welch (GSS / Goodestone Racing)
For the Persona’s final BTCC campaign, the team entered under the Goodestone Racing banner with Dan Welch driving the #17 car in a bold blue, fluorescent yellow, and black GSS (Goode Stone Supplies Ltd) livery—scoring points at Thruxton before retiring the chassis at the end of the season.
A Cult Classic for Proton Enthusiasts
Although Welch Motorsport operated on a fraction of the budget of factory-supported teams like Honda, MG, and BMW, the sight of a widebody Proton Persona spitting flames on downshifts through Paddock Hill Bend at Brands Hatch remains a proud chapter in Malaysian automotive history.
