Images revealing the new BMW 4-series cabriolet have been leaked online, ahead of the car's official reveal.
The shots of the new convertible, which appeared on a BMW blog site, are reputed to be from a brochure and - if accurate - show the new cabrio in production form with its roof down.
It's also pictured fitted with an optional bike rack, while an interior shot reveals some of the available trim combinations.
Previously a lightly disguised 4-series cabriolet, the second body style in the new 4-series range, had been spotted undergoing testing in Italy.
The new BMW convertible is expected to weigh slightly more than the conventional 1525kg 4-series coupé on which it is based.
Engine options have yet to be confirmed but are expected to be similar to those offered in the coupé, and include a turbocharged six-cylinder petrol and a four-cylinder diesel.
The new BMW 4-series cabriolet is expected to go on sale in 2014. Official pricing has yet to be announced but the car will command a premium over the coupé, which starts at £29,200.
BMW has also recently revealed its BMW Concept M4 coupé, the production version of which is expected to launch in mid-2014 for £60,000.
