Well, that’s interesting. Mercedes-Benz appears to have inadvertently unveiled its new Mercedes-AMG CLA45 S a little early thanks to a bug with its German configurator.

First discovered by an eagle-eyed AutoBild reader, the image appeared on the official configurator for the CLA35 (somewhat bizarrely, when clicking an icon for information on the CLA35’s AMG Night Package).

From what we can tell, the Stuttgart-based firm has since plugged the leak, removing the rogue picture from its website.

Though frustratingly low-resolution (have a look at the zoomed-in version below), the image does appear to show the model wearing a “CLA45 S” badge, with that final letter indicating its position at the very top of the range. The model pictured also boasts quad tailpipes, an aggressive rear diffuser, a cheeky boot-lid spoiler, darkened taillamps and new alloy wheels (the latter framing red brake callipers).

While power figures have yet to be announced, the CLA45 (like the upcoming A45 hatch and sedan) is expected to be powered by a turbocharged 2,0-litre four-cylinder petrol engine offered in two states of tune.

The base model will reportedly develop around 285 kW, while the S-badged model is expected to boast about 314 kW. Both will employ a new, sophisticated version of the German brand’s 4Matic all-wheel-drive system (complete with a dedicated “drift mode”), along with an eight-speed dual-clutch transmission.
