"There's room to improve on everything, the full package really. We were weak at some of the open, fast and flowing tracks like Sydney so we need to work on that, but if we can go well in testing then I'm pretty confident the rest of the year will be good."
The Gold Coast-based Aucklander was content with finishing fifth overall in 2013, but his championship hopes have increased greatly in this his seventh full season in the "main game".
"I've been around long enough that I have to shoot for it now and I think fifth last year was good enough for the way things were, but with what we've laid down for this year I think we can shoot for the top," he said.
Van Gisbergen started last season in controversial circumstances after walking out of a three-year deal with Stone Brothers Racing, citing personal reasons, only to sign for Tekno Autosports just seven weeks later.
"Obviously we started last season with a lot of talk about what had gone on in the off-season but once we got going we started with a win, and had a pretty good season overall, I enjoyed it a lot," he said.
As well as his V8 Supercars commitments, Van Gisbergen is keeping busy behind the wheel in New Zealand and Australia, racing drift cars plus the occasional V8 endurance event; he will also continue to do some testing in a rally car.
"You've got to keep playing and keep driving," he says. "A few of the drivers here [in Sydney for testing] were complaining that they hadn't driven anything since the final round last year, whereas I've had three weeks off since September so for me this is probably the most race-fit I've ever been coming into a season."
Van Gisbergen will be joined by V8 veteran Fabian Coulthard and 20-year-old Scott McLaughlin, making up a three-pronged New Zealand contingent in the 25-strong V8 Supercars field.
The opening round of the V8 Supercars Championship will begin on February 27 at the Clipsal 500 in Adelaide.
