With Holden slated to end production at the end of 2017, It’s only a matter of time before the Holden name is associated with badge-engineering. This means that awesome models like the Commodore will be gone forever. But, before that happens, HSV just might give the Commodore one last hurrah – one that’s fitting of an iconic car such as this. First, there’s the GTS-R that we learned about after HSV trademarked the name last year. Now, if reports from Motoring are to be believed, the Commodore will also get a more powerful version that uses the supercharged V-8 from the previous Corvette ZR1.

This means that for Holden’s final year as an auto manufacturer, it will bring out two awesome versions of the Commodore. The GTS-R is expected to come standard with GM’s 6.2-liter LSA V-8. The rumors so far have yet to produce working performance numbers, but the current GTS makes 577 horsepower and 538 pound-feet, so it should have at least that on tap, if not more. Then there’s the beefier version that’s being called the GTS-R W1, which is apparently still in development but with the ZR-1 engine should come with up to 638 horsepower and 604 pound-feet of torque on tap. That makes it a four-door ZR-1 in about every way.

With that kind of output, the W1 could turn out to be the question Australian-built model with a 62-mph sprint that comes as quickly as 3.5 to 3.7 seconds – now that’s one fast sedan. To put that into perspective for you, the new Porsche Panamera runs the 62-mph sprint in as quick as 3.6 seconds with 550 horsepower and 567 pound-feet on tap. The Maserati Quattroporte comes with 523 horsepower, 524 pound-feet, and a 4.6-second sprint to 62 mph. Holden may be living on borrowed time, but it’s going to climb into the ring with the big boys before it goes.

Leaving a Lasting Mark on the World

Now that you know about the big news, let’s talk a little more about the details. The W1 is rumored to have a price tag of about $130,000 at current exchange rates, and will only be produced in just 250 examples. Furthermore, the W1 is rumored to get upgraded brakes, a new body kit, and a bespoke suspension system from Supashock to go with a Tremec six-speed manual transmission. It’s pretty sad that Holden and HSV as we know them are about to be gone, but at least one of its best models will still be around for us to admire every now and then. As the final model, and 250 of them sporting a ZR-1 drivetrain, the GTS-R W1 is a collector’s item in the making. Now, if only we could get Chevy to bring the same enhancements to the Chevy SS for 2017!
