In many countries the value is much higher. Portugal and France (two
that I know about) have passed 50%. And that is an average of the whole
market, influenced by the smaller cars where the diesel advantage is
not very big and where gasoline engines are still being sold.
I have read that in cars like Toyota Corollas and bigger ones the Diesel
percentage can be 90%. Note that part of the reason for this choice is
performance. The turbo diesels are getting around 85 HP/litre while many
naturally-aspirated gasoline engines have less than that (and increasing
displacement is an expensive option in some countries because of taxes).
Of course there are turbo gasoline engines, but those have very high
consumption (a turbo gasoline must have lower compression ratio =
less efficiency). There is now a new technology, turbo gasoline engines
with direct injection (VW, BMW/Peugeot), but the results might not be
good enough to invert the tendency.

Subaru will have a boxer diesel (next year, I think). Most of the
technology (injectors, pumps, ECUs, etc) can be bought from Bosch and
other suppliers. I don't know if there are Japanese suppliers with the
same level of technology (in Japan diesel engines are still not used much).
