1908/22 GN Thunderbug

This car competed in the Boulogne Trophy race at the Vintage Sports Car Club's Hawthorn Memorial Trophies Race Meeting at Oulton Park in June 2008.

It's Mark Walker's 1908/22 GN Thunderbug, with a 4,228cc V-twin engine created using two cylinders from a 9-cylinder radial engine. The GN cyclecar was produced between 1910 and 1925, originally with a V-twin JAP or Peugeot engine, and later GN's own 1100cc engine.

GN Cyclecars

These cars took part in the 2 hour long VSCC Team Relay Race for Pre-war Sports Cars at the VSCC's SeeRed and Richard Seaman Memorial Trophies meeting at Donington Park in May 2011.

They're both GN Cyclecars, number 32 is the 4.2 litre V-twin GN Thunderbug of Mark Walker and the other car is the GN Parker of Justin Maeers, with a 6124cc Gypsy Moth aircraft engine. The GN cyclecar was produced between 1910 and 1925, originally with a V-twin JAP or Peugeot engine, and later GN's own 1100cc engine. On 12 January 2016 I showed photographs of the GN Parker at the VSCC's 2008 meeting at Oulton Park.
