Order books have opened for the first ever Audi S3 Cabriolet, fresh from its debut at the Geneva Motor Show. The flagship soft-top is powered by a 2.0 turbocharged TFSI engine pumping out 300PS for a 0-62 time of 5.4 seconds and an electronically limited top speed of 155mph. As with every S model the Cabriolet includes quattro permanent all-wheel drive and S tronic transmission as standard. UK order books open in April with first deliveries expected in July. Pricing has yet to be announced.
