Hi ppl.....I gottah provisional technical data sheet from a dealer 2day...comparison o da new 1796cc enginez & da existing 2295cc (C230k)
Can sum1 more knowledgable than myself plz explain(in easy to understand termz)wot it all transl8z 2?
figurez in()are da current enginez
displacement cm3 1796(2295)
rated output kw/hp@rpm 141/192@5800 (141/197@5500)
rated torque nm@rpm 260@3500-4000 (280@2500-4800)
acceleration 0-62.5mph 6speed 8.1(8.0)
acceleration 0-62.5mph 5speed auto 8.0(8.1)
no info re:top speed
I got da info re emmissionz&fuel consumption 2....but i aint bothered wi th@!!
Duz it basically mean da old(existing enginez)av got more power&th@ it cumz in earlier(@lower revz)&da increased power is sustained 4 looonger(till higher revz)

As I read it, they made a simple trade.
Less displacement (and new balancer) = less vibration and friction
Less vibration and friction = higher available redline
Higher redline = more HP (or same HP with less torque and fuel consumption, in this case)

Personally, I've always preferred engines with a nice fat low end to the high-revving (I think of it as a more Japanese engineering style) plants, but others will certainly disagree. In other words, fuel efficiency aside, the new engine should be strictly a matter of driving taste.

I do suspect, however, that the available engine modifications will be fewer and more expensive - the reduced volume and already high peak revs suggest to me that they've tweaked this engine further than the old one to get into the 190h range. Don't expect to get 30hp gains from it with a $1000 pulley, or see any ECU mod that won't destroy the cylinders in a matter of days.
