The new car will also become the longest MQB car so far. The Golf, A3 Sportback and Leon five-door measure 4,199mm, 4,292mm and 4,315mm respectively. The Skoda Rapid, which fits under the Octavia in the Skoda range, is 4,483mm, while the larger Superb is 4,838mm.
This means that the Octavia will measure around 4,650mm, thanks in part to its larger saloon-style boot than the current model, which measures 4569mm.
The new Octavia - seen here almost undisguised - will follow the design language of the Vision D concept car more closely than the new Skoda Rapid, too. As you can see from the spy pictures, the Octavia features the same arrow-head-shaped C-pillar, narrow headlights and creased bonnet as the concept car.
The new car is also expected to get a more upmarket interior to distance it from the value-focused Rapid. Prices will rise accordingly, with the new Octavia expected to start from around £15,000 – cheaper than its MQB brothers, but more than the current entry-level Octavia's £13,385.
The new Octavia will make its public debut at the Geneva Motor Show in March 2013, with UK sales beginning shortly afterwards.
