The RAC has begun trials of Connaught Hybrid+ technology on two of its breakdown and recovery Ford Transits.

The retro-fit kits were recently tested at a government-approved facility, which showed they reduced both emissions and fuel consumption up to 25%.

The system uses compact super capacitors and benefits from regenerative braking.

Steve Lydon, RAC quality manager said: “We are constantly looking for ways of reducing our carbon footprint and reducing costs.

"The Connaught Hybrid+ technology trials we are undertaking I hope will tick both boxes”.
