LAY out the welcome mat for the fastest Skoda Octavia.

The rampaging Skoda Octavia RS 245 has arrived in Australia in sedan and wagon guise, starting from $43,390 plus on-roads for the manual four door.

According to Skoda, unlike the previous RS 230 which was offered in 2016 and only available in limited numbers, this new and more powerful RS 245 will become a mainstay of the Octavia range.

The nomenclature of RS 245 is a nod to the power - that's 245 horsepower in old-school language.

Under the skin is a 2.0-litre turbocharged petrol engine, good for 180kW and 370Nm of torque; making the RS 245 capable of performing the 0-100kmh sprint in 6.6 seconds for the sedan and 6.7 for the wagon.

Paying homage to its sporting lineage, both sedan and wagon body styles are available with a six-speed manual or a seven-speed dual clutch automatic transmission.

Manuals have become a rare offering these days, and keen drivers will love the option of a stick shift.

The RS 245 will also come with a electronically controlled, limited-slip differential, which Skoda says offers "greater traction and stability in corners at high speed, ideal for spirited driving when conditions permit”.

Among the special inclusions are a leather and Alcantara-trimmed sports trim, which also feature electrically adjustable front seats with a driver's seat with memory function, auto folding and dimming door mirrors, along with a special RS instrument cluster and door inserts.

You can spot the RS 245 over its Octavia siblings via 19-inch 'Xtreme' black allow wheels and black exhaust pipe outlets.

It's available in four colours, red, grey, white and pearl effect black.

"Skoda has always stood for getting more car for your money, which is easily observed in the new Octavia range. With this new, high performance Octavia RS 245, Australian fans will not just see 'more car', they're going to feel it too,” Skoda Australia's Michael Irmer said.

There are a range of packs available to customise the RS 245.

Tech Pack - RRP $2300: Automatic Parking Assist, Adaptive Chassis Control, Advanced Keyless Entry including Smart Start (KESSY) and alarm, a premium, 10-speaker Canton Sound System and Manoeuvre Braking Assist.

Luxury Pack - RRP $1500: Lane Assist, Side Assist with blind spot detection and heated front and rear seats.

The RS 245 comes with a five-year, unlimited kilometre warranty and roadside assistance, and capped priced servicing every calendar year.
