What is it? for a point

It's the Howmet Turbine LeMans car
Welcome to Autopuzzles.
....and Yes it is!
The Howmet Turbine experimental (TX) was an American sports prototype racing car designed in 1968 to test the competitive use of a gas turbine engine in sports car racing.
Planned by racing driver Ray Heppenstall, the TX combined a chassis built by McKee
Engineering, turbine engines leased from Continental Aviation & Engineering, and financial backing and materials from the Howmet Corporation
