Holden Special Vehicles is still no closer to confirming plans to enter the hot hatch segment even after Holden confirmed it will revive the high-performance VXR variants of the Astra hatch and Insignia sedan today.

The iconic Aussie brand announced this morning that it will add four sporty Opel-sourced models to its line-up in 2015; the three-door Astra GTC and VXR, Insignia VXR and Cascada convertible.

Both the Astra variants and the Insignia have previously been available in Australia under the Opel banner, and the Cascada was due to arrive last year before the European division closed its local operations in August.

It had been expected that Holden would pick up some of the pieces of the Opel range to bolster its small and mid-size offerings, with early speculation suggesting it would be the more mainstream variants, leaving the high-performance models open to HSV, which sold the previous generation Astra VXR under its own brand.

Despite Holden snatching the go-fast models, HSV boss Tim Jackson told Drive the decision hasn't affected any of its future plans.

"There are positives in it for us. The fact that it is already here means if we were to have any plans in that segment then there are some benefits," Jackson said.

"But the challenge for us is, and always has been, it is already a great car. So can we make it an even greater car and does that make sense for the consumer?

"Then, we have to ask the question internally, does it make sense for us from a business point of view?"

"We're working through a lot of things at the moment, and this doesn't alter what we're focusing on at the moment."

Opel has shown what could be done to make the Astra live up to the race-bred nature of HSV when it revealed the Extreme concept car at the Geneva motor show earlier this year.

The car featured a more powerful version of the 2.0-litre turbocharged four-cylinder, tuned to produce in excess of 224kW, and weighed 100kg less than the standard model thanks to extensive use of lightweight carbon fibre, including its wheels.

The Extreme also featured new bodywork with a race-style front splitter and rear wing for added downforce, plus had six-piston Brembo brakes and adjustable suspension.

Inside the cabin, it has lightweight Recaro seats and six-point racing harnesses.
