Nissan has
shocked the automotive world introducing
a 400HP engine that weights a scant
40kg (88lbs).
Named the DIG-T R, the 3 cylinder 1.5
liter engine has a power to weight ratio
of 10HP per kilo, besting even high
performance Formula 1 engines.
Carried aboard Nissan’s Zero
Emmision ZEOD the 500mm tall,
400mm long, and 200mm wide (19.68
x 15.74 x 7.78 in) package is one of
the most compact performance
engines every built and follows
Nissan’s new design goal of reducing
size and weight to achieve greater
performance.

Interesting.  And it's only just made it on to their fb page.

There's no something for nothing. What has been sacrificed to arrive at this spec?

Honesty could be a candidate

Reliability?

In all honesty it has a special program that assists it to recognise when someone is going to look under the bonnet, it then assumes the form of a tiny engine....

Probably a super engine, though I can't find much on the web about it since 2014.  Wonder what they've done with the thing since then? 

Special oil needed to keep wear down, not yer ordinary stuff.   Maybe not suitable for a taxi which you'd expect to do 200.000 miles.  Expensive as well.

Lots of used fast cars I see advertised seem to have low miles though, used for track days and the odd outing - not everyday cars. So it might be okay for that sort of thing.
