A Toyota Corolla might be a good option. It's a hybrid hatch that's at home around town as well as on the motorway. It's got an excellent reliability record with a warranty that can be extended up to 10 years (which makes it a good secondhand buy), while it's also very efficient in the real world. It's worth looking at the slightly smaller Toyota Yaris, too, or the SUV alternative - the Toyota Yaris Cross.
