HSV has ruled out a high performance GTS wagon to join its current stable of top shelf models.

Following the company's confirmation of the upcoming GTS Maloo ute last week, which will join the existing GTS sedan from later this year, there were murmurs HSV could potentially complete a high performance trifecta by building a GTS wagon based on its R8 Tourer.

Drive understands the company has dismissed the idea of adding a GTS Tourer because of the limited sales potential of the wagon.

An artist's illustration shows what it could have looked like with a similar exterior treatment as the sedan and ute, including unique front styling, larger air intakes and a powerful set of AP radical six-piston brake callipers with 390mm front and 371mm rear two-piece rotors.

A GTS Tourer would hypothetically feature the same 6.2-litre supercharged V8 engine seen in the sedan and ute, producing 430kW or power and 740Nm of torque – outputs that would endow it with a 0-100km/h sprint time of about 4.5 seconds.

It would compete with some of the hottest wagons in the world – and most likely for a much cheaper purchase price. Its 430kW/740Nm outputs would rival that of Audi's prodigious RS6 Avant wagon, which offers 412kW and 700Nm from its 4.0-litre twin-turbo V8 engine.

HSV was reticent to talk about a GTS Tourer when quizzed by Drive.

"Our company policy is not to speculate," said HSV marketing manager Damon Paull.

"I can talk about GTS Maloo but I can't talk about future product plans."

Having undertaken extensive research to complete both the GTS sedan and GTS Maloo, HSV would be well versed on the necessary compliance and engineering work needed to complete a GTS wagon.

There were whispers of the project within the industry last week, with some insiders adamant that the project will happen.

But a source close to the company told Drive that HSV is now highly unlikely to go through with any development plans.

Even if sold in limited numbers, a GTS Tourer would help reap more sales for the performance arm as it gears up for Holden's confirmed manufacturing closure in 2017.
