At the Geneva Motor Show, a striking contrast between electrics and gas-guzzlers

This year's Geneva auto show is crowded with new cars flaunting electric and autonomous technologies meant to help unclog city streets and fight global warming and air pollution.

That didn't stop car makers from offering their traditional crowd-pleasers: ostentatious displays of overweening horsepower in sleek, gas-guzzling, and obscenely expensive sports cars.

The contrast isn't unusual when it comes to auto shows but it was particularly striking this year, as automakers push to get ahead of expected shifts toward electric and autonomous vehicles — while high-end cars remain a profitable business.

French automaker Renault unveiled its futuristic and funky EZ-Go, a six-seat self-driving electric vehicle that aims to bridge public and private transportation needs, with options like on-demand pickup, like by a taxi. It features a rooftop opening that allows passengers to enter by a ramp for easy access.

Renault chief operating officer Thierry Bollore called it an "urban, 'robo-vehicle' electric concept that can be tailored for public and private services."

Mercedes-Benz rolled out its EQA concept car, a compact battery electric vehicle with a virtual radiator that changes appearance depending on the selected driving program.

Volkswagen showed off its I.D. Vizzion large electric sedan, shown in an autonomous version without a steering wheel, calling it a "smart device on wheels."

Companies have invested billions in electric cars even though they still appeal to relatively few buyers. Car makers are positioning themselves for a future tipping point in which longer battery range, more places to charge, and falling costs make electrics as attractive as conventional vehicles.

Driverless cars, meanwhile, remain in the testing phase. Analysts at IHS Market forecast that autonomous cars will have their first year of significant volume sales in 2021.

To explain their appeal, BMW CEO Harald Krueger used the example of a Chinese customer who currently spends 30 days out of the year sitting in traffic jams. "If I can give him as a gift 28 days through autonomous driving, so that he can take a break, listen to music, or maybe look after email, then that is a comfort factor that the customer will want to have," he told journalists.

"The company that doesn't offer that will be the one that doesn't sell the car."

Internal combustion engines and cars offering an exciting experience for real human drivers remained very much in evidence, however.

Luxury sports car maker McLaren showed off its 211-mph (340 kph) Senna, named after the driver Ayrton Senna. The car is styled like a race car with prominent intakes and a rear spoiler. The production run of 500 is sold out at the factory, at a starting price of about US$1 million at current exchange rates.

Ferrari offered the curvaceous 488 Pista, whose 710 horsepower engine, fed by large rear air intakes, has been fine tuned to emit a "unique and unmistakable" roar as the car accelerates.

Italian designer Zagato displayed the IsoRivolta Vision Gran Turismo in a mock-up version. The vehicle has a carbon-fiber body with giant arched wheel wells and a dark glass cockpit for two. The five expected production models should sell for north of US$1.86 million each.

The Geneva Motor Show runs through March 18.
