In 2021 Turntide acquired three North East businesses to establish our presence in the UK – those businesses were Borg Warner in Gateshead, Hyperdrive in Sunderland and Avid in Cramlington. The acquisitions allowed us to extend our Smart Motor System to the transportation sector and help turn the tide on climate change.

There is a massive change happening across Transportation. Companies are working furiously to develop new electrified platforms to meet the demands of their customers and do their part to reduce carbon emissions. Our Turntide for Electrification solutions help ease the customer journey and accelerate their transition. The faster they can transform, the better it is for our planet.
