Mercedes-Benz will launch a few vehicles at the Auto Expo including a new variant of the C-Class. The C250 CGI is the next generation of petrol engines from the German marque with direct injection and turbocharger.  The 1796cc motor produces 200bhp of power and 31.6 kgm of torque capable of hitting 100kmph in 7.4 seconds and hitting a top whack of 240kmph.  This next gen engine uses Piezo injectors which have multiple injections (just like diesels) giving better fuel economy at sane speeds and immense power when you floor the pedal.
