Outright pace and power - Fiesta Ecoboost (turbo engine does offer a lot of advantage - more power and torque than a 1.5L or 1.6L NA engine)
Handling - Mazda2 SkyActiv (light chassis and responsive engine)
I forgot to include the Hyundai Accent CRDI. How good is the handling and performance of this turbo diesel subcompact? The spec sheet lists its output figures similar to some bigger diesel engines.
