Comment A very promising engine (Score 1) 269
Not only is it a two-stroke engine, which are inherently more efficient than four-stroke engines, but it also limits the moving parts to a minimum. And Lotus never boasts about something it cannot do. However, I'd like to see a multicylinder version of it.
And that's no mean feature when you see the number of moving parts in today's engines fitted with variable valve timing/lift systems (which, of course, the switch to electric propulsion will avoid altogether).
The question is, however, is it too late? And imho, there is a "yes" and a "no".
Yes, the electric motors have been long proven to work.
No, the weight/energy ratio of electricity sucks. No, other (really!) "CO2 clean" fuels already exist, with engines already able to run on them (this particular engine included).
The future looks promising anyway. Now, I just wish that the car manufacturers turned more effort into removing weight. Even if that means stepping back on safety features - after all, nothing has been done yet on the driver training front.
