Williams have released the first images of their car for this year, albeit a computer-generated mock-up as the FW36 is not due for its official launch until next Tuesday on the first day of the opening pre-season test in Jerez.
Aside from the new engine regulations, as the cars this year will be powered by 1.6-litre V6 turbo-charged units instead of 2.4-litre V8s, the Williams highlights the key aerodynamic changes.
The car possesses what has been described as an 'anteater-style' nose, which is long and tapered to cater for the new aero-package updates as the tip has to be at a height of 185mm, significantly lower than before.
Symonds believes Williams has made a significant step in the aero department he hopes will propel them up the grid.
Last season represented the worst in the Grove marque's history as they collected a miserable five points, finishing ninth in the constructors' championship.
Symonds said: "F1 is still going to be an aerodynamic formula in 2014.
"There are some significant changes: the nose is lower than last year and the front wing is narrower, which means the end plates are now more shrouded by the front tyre.
"The rear wing isn't as deep as last year and the beam wing below it is no longer permitted, and we've also lost the ability to use the exhaust to enhance aero performance.
"But I'm confident we'll be closer to the front aerodynamically than we were last year. Our ambition for the year ahead is to have a strong 2014 season."
Naturally, the major change surrounds the new powertrains, which for this year incoporates the ERS (energy recovery system).
ERS combines two electrical motor generator units, one of which works like the old KERS system that stored energy under braking to provide a power boost for 6.7secs.
This year there is a second unit that harvests waste energy from the exhaust flow, allowing for 30 seconds of additional power.
All the extra power has placed demands on the car's cooling system as Symonds said: "There's a lot more technology on the cars this year.
"We've had turbo-charged engines in F1 before, but what's different this time is that it is much more than just an engine change - it is a completely different system.
"We've gone from a slightly hybridised normally-aspirated engine to a fully-integrated hybrid power unit with novel technology at its heart, and overall the cars will need more cooling this year.
"The demands on water and oil cooling may be slightly diminished, but the ERS system is significantly more powerful, and hence needs more cooling."
Williams benefit this year from Mercedes' power units, whilst there is also an eight-speed gearbox for the first time in the team's history.
"This is the first time Williams has worked with Mercedes in F1 and we've been very impressed," added Symonds.
"Their professionalism and commitment have been notable and we're as confident as we can be that the power unit will be competitive."
