Lowndes got past Whincup in race two, and then pressured van Gisbergen in the following run and was the main focus fighting for positions.
“I wouldn’t be racing if I didn’t think we could still win races and try and win championships,” Lowndes told v8supercars.com.au.
“Clipsal didn’t go to plan but most people will say that because of the crazy weather and the way it unfolded on Sunday – there were a lot of championship contenders who weren’t up the front where they should’ve been.
“All in all I think that we’ve had a very strong showing in Tassie last year and I’m going down there with a lot of confidence we can make the car thee same as we did last year.”
Lowndes shocked the field with his speed early in the Symmons Plains event in 2015, setting his top three practice time on hard Dunlop tyres while his competitors were on the quicker soft compound.
He earned all three pole positions, two wins, and a sixth position on Sunday after taking out David Reynolds and coming back from a drive-through penalty.
The car’s performance last year is encouraging, with Lowndes focused on repeating the feat with 2016 engineer Ludo Lacroix, who doubles as the team’s technical director.
“We can try and win more down there – the car last year was really good, probably one of the best cars we’ve had down there and we haven’t lost focus on what we had in the sense of setup,” Lowndes said.
“There’s probably more pressure on Ludo going down there knowing we had a good run last year and as a new engineer with me it’s going to be a great challenge.”
After the rain-affected, chaotic Clipsal 500, Lowndes sits 14th on the points table, while his teammates are second and third, with Whincup just 10 points ahead of Shane van Gisbergen.
Lowndes is only 54 points adrift of Whincup, though, with just one round down.
