The updated Skoda Octavia RS was unveiled overnight with a smidge more power for the petrol model.

Visually, the Octavia's controversial new headlight arrangement is a little less obvious in the RS, as the sports model has a completely dark grille that blends into the secondary headlamp units.

The RS models are distinguished from lesser Octavias by their more aggressive front fascia, a full width red reflector and black diffuser style element at the rear, and LED tail-lights.

Both the RS liftback and wagon ride on standard 17-inch alloy wheels with red brake callipers, and a sports suspension setup that's 15mm lower to the ground than regular Octavia models. Skoda has also increased the rear track by 30mm compared to the outgoing RS.

The interior features aluminium pedals, plenty of RS badging, ambient lighting, and perforated leather for the steering wheel. There's also sports seats with better lateral support and integrated headrests, and can be upholstered in either a combination of leather and fabric, or faux suede.

Options include 18- and 19-inch rims, a 9.2-inch infotainment touchscreen, and Wi-Fi hotspot with 4G LTE connectivity.

As before, the Octavia RS is available with two engine choices: a 2.0-litre turbocharged petrol motor, and 2.0-litre turbo-diesel.

Power for the 2.0-litre petrol has been upped by 7kW to 169kW, with maximum torque output still rated at 350Nm between 1500 and 4600rpm. That's good enough to hurl the RS from 0-100km/h in 6.7 seconds and on to a top speed of 250km/h.

Front-wheel drive and a six-speed manual are standard on the Octavia RS petrol, with a six-speed dual-clutch transmission (DSG) optional.

Skoda has kept the 2.0-litre turbo-diesel pretty much the same. The TDI mill produces a maximum of 135kW of power, and 380Nm of torque from 1750rpm.

According to the company, the RS diesel is capable of completing the 0-100km/h run in 7.9 seconds, and hitting a top speed of 232km/h. The RS diesel is available in front-wheel drive with a six-speed manual or DSG, and in all-wheel drive wth a six-speed DSG.

Australia

As with the wider 2017 Octavia range, the RS models will make their Australian debut around the middle of next year. Further details will come as the launch date nears.
