Red Bull Racing confirmed during the Canadian Grand Prix weekend that it has retained the services of design guru Adrian Newey, who had been linked with a big-money move away from Formula 1's reigning title holders.

It seems, however, that Newey might not necessarily be a regular fixture on the F1 pit wall in subsequent seasons.

He's been a critic of the Formula 1 technical regulations, which place tight constraints on the kind of innovation he specialises in.

What's more, he's apparently expressed a desire to work on other projects for Red Bull Technology, a subsidiary company that currently builds the chassis of the F1 machines.

Something that might occupy his time could be developing a Red Bull road car, something which might give him more freedom than F1. It's a scenario which could draw a modern parallel with Gordon Murray's work on the McLaren F1 in the 1990s.

This development wouldn't come as a total surprise – back in 2012 Red Bull Racing chief Christian Horner told Autocar that road cars were on the agenda for his Milton Keynes company, which is keen to spread its capabilities far beyond F1.
