The acceleration deficit is largely down to extra mass. The addition of the electric motor and a rear-mounted battery pack (suggested to have a capacity of up to 13kWh) add in excess of 200kg to the kerb weight, but that will be offset in part by instant, electric-propelled torque and the ability to run for up to 30 miles in electric-only mode.

The regular petrol is set to be the quickest of the Octavia vRS line-up. Details aren’t confirmed, but sources suggest that the Volkswagen Group’s familiar EA888 motor will be tuned to deliver close to 250bhp, while torque could rise above 280lb ft. Performance is expected to improve over that of the existing car, with the 0-62mph sprint taking approximately 6.5sec.

As before, there’s tipped to be a choice of dual-clutch automatic and manual transmissions. However, it’s yet to be confirmed whether either the PHEV or the petrol will get the Volkswagen Group’s VAQ electromechanical limited-slip differential. This hardware did appear on the outgoing vRS 245, so it’s likely to feature once again on the pure-petrol versions.

It’s expected that the diesel-powered vRS TDI will use essentially the same 2.0-litre engine as before, with 181bhp and 280lb ft. However, changes to the engine’s internals and its management system will ensure that the unit meets the latest stringent emissions regulations.

Elsewhere, the vRS is expected to be as versatile as ever. Alongside the three different powerplants are the choice of hatchback and estate bodystyles and front- and four-wheel-drive configurations.

Externally, it’s expected that the Octavia vRS will receive the usual muscular styling makeover and the option of more extrovert colour choices. The interior, meanwhile, will benefit from heavily bolstered sports seats and bespoke trim and graphics.

On-sale dates and prices are as yet unknown, but first deliveries are expected at the end of this year. The plug-in hybrid model could prove to be the priciest Octavia yet, potentially costing up to £34,000.
