With all the electronics in modern F1 cars, how do the modern day F1 cars compare in times vs. '90s F1 cars?

It depends which part of the 90s. In 1993 the best F1 cars had Anti-Lock Brakes, traction control, launch control and active suspension, but these were all banned in 1994. Even nowadays, these electronic aids are not allowed in F1 cars. Thus, for a long period of time the 1993 cars were effectively the most technologically-advanced cars in F1, and probably remained so until about 2002 or 2003.



If I had to compare the 1993 Williams FW15C car (considered to be the best that season, and the last car for a long time to have electronic aids) with the current Red Bull (which has KERS and DRS but no traction control and other electronic aids), the Red Bull would win hands-down. This is because of its great aerodynamic efficiency which allows it to corner much faster and so requires less braking going into a bend. It might be true that the 93 cars had a bigger engine (and hence more top speed) but this only made the car go faster on a long straight and the modern cars have DRS on the straight anyway. What the 1993 car gained on the straights it lost in the curves, so on an overall lap the modern cars would lap faster. This does not mean that the modern cars are the fastest ever - most lap records during a race are still held by the 2004 cars, which basically had slightly less aerodynamics but a more powerful engine (unrestricted V10 as opposed to the modern 18,000 rpm V8).
