It is rather hard not knowing the full context. But the only thing I see in the snippet that raises any flags is the word 'jet'. I would venture that is a translation glitch and it is a 1.4L turbo engine in a 600kg chassis which at first blush does not seem outside the bounds. As has been pointed out, it can be ballasted up. Is this is a future P-2? Some hot production 1.4L turbo?
L.P.
