Braking news! Miss burnet has a gas guzzling car, it does 2 mpg tut tut tut (miles per gallon). she sould get a toyota Verso, hybrid car.

A hybrid car features a small fuel-efficient gas engine combined with an electric motor that assists the engine when accelerating. The electric motor is powered by batteries that recharge automatically while you drive.

Hybrid cars also gain efficiency from:

Smaller and more efficient engines.
Regenerative braking - the electric motor that drives the hybrid can also slow the car. In this mode, the electric motor acts as a generator and charges the batteries while the car is slowing down.
Periodic engine shut off - when a hybrid car is stopped in traffic, the engine is temporarily shut off. It restarts automatically when put back into gear.
Advanced aerodynamics - to reduce drag
Low-rolling resistance (LLR) tires - narrow, stiffer tires have less drag
Lightweight materials - increases the efficiency of hybrid cars.

These gas-electric hybrid cars are now available in North America:
