Force India on Tuesday brought up by the rear by becoming the last Formula One team to reveal its 2011 car.
After some website glitches, the VJM04 was launched online by the Silverstone based team.
"Everything is different, but visually a lot of it is subtle," insisted the team's new technical director Andy Green.
The most obvious change to the car compared with its predecessor is the switch from a conventional roll-hoop to a Team Lotus-style 'blade' solution.
"But there are a lot of (other) differences under the skin that people won't necessarily notice," added Green.
The Mercedes-powered car will debut at Jerez on Thursday.
