I imagine they’re so stuck on it because when it comes to electrics they are losing against the cheaper china EVs.

Volkswagen saw its electric car sales decrease by 2.7% in 2024 when Audi fell even harder, with EV deliveries declining by 7.8%. Demand for the VW Group’s zero-emission models decreased by 3.4%, proving that the transition to an all-electric lineup will be bumpy.

Not that they’re alone with it.

Bentley has also revised its electrification roadmap. The British luxury brand has delayed the launch of its first EV from 2025 to 2026 and extended its goal of becoming an all-electric brand from 2030 to 2035. Similarly, Lamborghini has postponed the debut of its first EV, the Lanzador, from 2028 to 2029.

General Motors also had lofty EV goals but has had to readjust them to suit market needs. As a result, the Detroit-based marque is developing plug-in hybrids to meet demand, with the first PHEVs due in 2027. Land Rover and Kia have also made similar adjustments to their EV roadmaps.
