A Neon R/T runs 0-60s in 7.5 seconds, which is reasonable for the cost.
2004 - 2004 model comparison.
Let's compare the SRT-4 with the S2000. If you care, the SRT-4 gets better gas milage and has more cargo capacity. The S2000 has a shorter turning circle, better handling, and better aerodynamics (though Honda hasn't published the S2000s aerodynamics, it's obvious better). The SRT-4 is a 2.4 turbo, making a ton of torque 2000-4000. The S2000 is a 2.2 with a revised form of VTEC, it makes almost 100 lbs of torque less than the SRT-4 at at a high 6500, but revs really high - so technically you could consider that "low". Both cars weigh the exact same pratically too, with the S2000 weighing some 15 lbs extra only.
Two extra major differences are that the Honda makes 10 more HP than the Dodge, and the SRT is FWD while the S2000 is RWD.
The S2000 has great performance for a standard 2.2 DOHC without a doubt, but is simply at a loss to the performance - price ratio the SRT-4 offers.
