Yes, they have. Big technology and reliability enhancements, as well as much more power. Turbo cars now have more torque and a better power curve than NA cars.
Remember when turbo cars had boost lag and only made power high in the rev range? Ain't like that anymore.
I had a VW Jetta Wolfsberg Edition turbo.. That thing would eat my 2007 GT's lunch above 80mph. It pulled harder at 130 than it did at 70. It was crazy. Turbos have come a long way, and they've gotten reliable, powerful, and efficient. It mostly lies in the tuning and precision, which for those of you who remember, Chevrolet's Cross-Fire injection wasn't but a few years away from the Fox's turbos... both "cutting edge" of their time and known to be horrid now.
And as sad as it may sound, I almost went with a turbo diesel Jetta instead of another S197 to save money.
