Depending on whose figures you accept, half of all small pass cars in Europe are already diesels, and of these most vane type turbine control turbochargers (VNTs) are electrically actuated. If you accept the loose definition of electronic control, virtually all new turbo applications have electronic modification of the pneumatic turbine controls wastegated or VNT.
Ford diesels have had electronic VNT turbos for 5 years. The '08 Ford Super Duty truck 6.4L engine has series sequential turbos now and can boost as high as 36-38PSI (10-20PSI is normal roadload boost). On this engine the high pressure turbo (small one) has direct electronic control of the VNT. The low pressure turbo(large one) is free floating (no turbine control).
