Actually, over here in the states, We're seeing cars come out with LESS power for efficiency reasons.
Example:
2014 Chevy Cruze 2.0L Turbo diesel (US Market): 148 HP
2013 Chevy Cruze 2.0L Turbo diesel (everywhere else): 168 HP
more examples:
Old Nissan Sentra: 140 HP, 177 HP, or 200 HP (engines: 2.0L, or 2.5L)
New Nissan Sentra: 130 HP. (engine: 1.8L only)
old Chevrolet Cobalt: 155 HP, 175 HP, 205 HP, or 260 HP (engines: 2.2L, 2.4L, 2.0L supercharged, 2.0L turbocharged)
replacement Chevrolet Cruze: 138 HP (1.8L or 1.4L Turbo), 148 HP (2.0L turbo diesel)
Old Nissan Versa: 108 HP, 120 HP (engines: 1.6L, 1.8L)
New Nissan Versa: 108 HP (engine: 1.6L. odd considering the old 1.8L made up the bulk of all Versa's sold here)
So it stands to reason that 1000HP everyday cars will NEVER happen. Fuel economy sells.
