We have been busy in recent months preparing two very different Alvis Speed models for the 2015 ERA Trans-America Challenge – one a Speed 20 fitted with a Speed 25 engine, the other a Speed 25 Charlesworth Drophead Coupe. The event starts early next month in Halifax, Nova Scotia on the east coast of Canada, crossing the USA to arrive in San Francisco on the west coast on 28th June. The cars will cover 9,500km over a mixture of road, gravel and forest track. Look out for updates on their progress on our news pages. Watch the cars being loaded here
