We'll see what it really makes. Thinking it cannot make more is just silly. You are completely underrating European emissions and how much they have to screw with the tunes on these cars to pass that crap.

The new twins prove the point that Europeans emissions aren't holding back much of anything, 2.5% is nothing to write home about. The turbo cars are balancing reliability and fuel economy with their tunes, easy to crank up the boost but you can not break physics, there's only so much power to be made by burning fuel in a 1.6L combustion chamber. Those F1 engines wouldn't last 20 laps on their max power tunes and often raced at <1000hp levels and even then most blew up. Niki Lauda finished 3 races in 1985 when Mclaren claimed the constructors championship off Alain Prost's back.
Let's back up here, how much do YOU think the aftermarket can squeeze out of this engine reliably? How much headroom do you think is left?
