Elon just bought GM?????

VW had a diesel/electric hybrid (Bluemotion) that got 70+mpg. Diesel engine was just a generator with wheel mounted electric motors. No battery and excellent mileage. What happened to that? Even my 2011 TDI Jetta got 50mpg. It is possible, certain groups do not want it possible.

The cars have a fuel efficient engine, aerodynamic body, low ride height, auto stop-start, programmed battery charging system, longer gearing and low rolling resistance tires. On 30 June 2011 a Volkswagen Passat 1.6 TDI BlueMotion set a world record for the greatest distance driven on a single tank of fuel, recognized by the Guinness Book of Records, achieving 1,526.63 miles (2,456.87 km). The average consumption amounted to 74.8 miles per US gallon (3.14 L/100 km; 89.8 mpg‑imp).[10]
