"Come into the garage and I'll show you around the car," smiles the very amiable Peter McCool, former chief designer of the talented nucleus of the Super Aguri Formula 1 team, whose ideas played a large part in Brawn's title-winning 2009 campaign. "But don't touch it..." he warns nervously.
McCool is now technical director of Aguri Suzuki's latest international racing project: the Amlin Aguri team, which is one of 10 squads in action at Donington Park's inaugural two-day Formula E open test.
The car that must not be touched is being recharged, a process that takes approximately 45 minutes, and the team - understandably - doesn't really want an electrocuted journalist on the garage floor.
