Hello,
The most important difference to my opinion, except for the headlamps, is the rear axle ratio.
US 230’s have a 4,08 reduction rate, while euro models have 3,75.
That makes quite a difference in engine speed, noise and … fuel consumption.
Speed in miles/hour with a wheel diameter of 25,4 inch.
r.p.m. US 4,08 Euro 3,75
2500 45 50
3000 55 60
3500 64 70
4000 73 80
Greetings,
Erik
