Romain Grosjean believes that Lotus can show the rest of Formula 1 how good they can be following a nightmare 2014 campaign.

After race wins in 2012 and 2013, the Enstone-based outfit endured a miserable season last year, mustering just 10 points between Grosjean and teammate Pastor Maldonado.

However, the French driver has suggested that Lotus could surprise their rivals at the season-opening Australian Grand Prix next weekend.

He told reporters: "This season will be very much about reminding people how good Lotus F1 Team and Romain Grosjean can be. People have very short memories in Formula 1 and it's true we had a tough fight for results in 2014 so some people have forgotten the performance we showed in 2013 and 2012.

"We have a lot more potential for strong results this season so we'll be pushing to show that at every race, and what better a place or time than at Albert Park.

"This time last year we were nowhere, so this year is particularly positive. For sure, we still have work to do and our car's not perfect, but we have a great platform from which to build and I'm sure we'll have lots of good developments to come with the E23."

Lotus have ditched Renault engines for this year in favour of Mercedes power units.
