I was wondering if someone could answer a question that I've been thinking about for awhile. I've been driving a 1992 2.3 190E for about two years. I know someone who drives a 1995 Toyota Camry, and when I drove it I noticed that it has much better acceleration than my 190E. Why is this? I checked the specs for both cars and came up with the following:

190E
130 horsepower
in-line four cylinder
2995 pounds
SOHC

Camry
125 horsepower
in-line four cylinder
3080 pounds
DOHC

Since the power-to-weight ratio for the two vehicles is very similar, why is there such a big difference in acceleration? Is it becuase my 190E has a SOHC while the Camry has a DOHC? That's the only real difference that I could find. Does anyone else know why this is?

Note: Even though my 190E doesn't have as much acceleration, I greatly prefer it over the Camry.
