A new global study shows that the allure of Ferraris and Lamborghinis is diminishing for a new generation of environmentally responsible drivers who value green credentials and high-tech features over performance and styling.

A Deloitte survey of over 23,000 19-to-36-year-olds shows that the majority of young people (61%) still want to buy a car within the next three years but that the automobile is slowly beginning to lose its status as a symbol of cool and independence.

Although just 8 percent of all respondents stated that they never intend to buy a car, those who are in the market for a set of wheels don't care about 0-100km/h times, horsepower or power-to-weight ratios. Indeed, 59 percent said that within the next five years, they expected to be driving a vehicle with an alternative powertrain such as a hydrogen fuel cell or an electric hybrid engine.

Aware that car companies, Google and Apple all have designs on the future of in-car technology, 57 percent said that they would like to customize whatever technologies were on board after they have purchased a car, rather than be tied to a format or operating system.

"Affordability is the mantra for Gen Y consumers who don't already own or lease a vehicle," Craig Giffi, vice chairman of Deloitte, said. "When asked what purchasing criteria matter most to them, a majority cited cost-related items such as the vehicle's price tag, fuel efficiency and payment options."

The survey polled the opinions of over 23,000 people in 19 countries, including 2,000 US consumers.
