Motoring journalist Erin Baker gets behind the wheel of Porsche's latest 911 sports car. Michael Mauer, current chief designer at Porsche, and Tony Hatter, design manager on models including the 993, describe to Erin what it takes to design a car that will be both instantly recognisable and desirable. From the initial sketch to full-scale models and the final product, Erin gets under the bonnet of the design process. Porsche is also the largest high performance vehicle manufacturer in the world. Erin asks what the future holds for Porsche design, and driving for pleasure, beyond the internal combustion engine.
