Thatcham Research tasked with testing EV maker's new underbody after concerns raised over repair costs

Tesla is working to address criticism that its huge ‘megacast’ underbody sections are too hard to repair, pushing up the cost of insurance, Autocar has learned.

The American EV giant pioneered the use of giant casting machines – which it calls 'gigapresses' – to eliminate almost 100 underbody parts with a single aluminium piece, cutting costs and speeding up production.

Their wariness is partly down to the unknowns surrounding repairs.
