The first pictures of the all-new Mercedes-Benz A-Class have been revealed ahead of the car's debut at the Geneva Motor Show. Focus on the new iPhone integration system is understandable as it will be introduced to the new A-Class when it launches in April, but the retro look of the interior is worthy of note. A Mercedes-developed app works the system and menus are selected via a rotary controller on the console.

Siri can be used to send emails and texts, although background road noise may stop this working effectively. Director of Infotainment and Telematics, Ralf Lamberti, said: "The A-Class will be the most connected car on sale when it is launched in April, with very fast access to iPhone files. Owners who are tech savvy or 'digital natives' will choose cars with connectivity and a screen, but functions will be controlled through a mobile device." The service will also be extended to work with other mobile operating systems. "We can't ignore other devices.

"The next step is to develop a version for Android and Windows-based mobiles." The iPhone integration system is set be fitted in the B-Class and C-Class later in the year. Engine options for the A-Class will mimic those available for the B-Class, including five gasoline engines ranging from 108hp to 201hp and four diesels from 120hp to 350hp. AMG will later release a new A-Class powered by a turbocharged 2.0-liter engine capable of 350hp. As a direct rival for the Audi A3 and BMW 1-Series, the new A-Class will be priced accordingly.
