I keep reading about and hearing that Kimi is going to race the shorter wheelbase Lotus.
How much shorter is the wheelbase?
I have not seen any figures mentioned anywhere.

what? Assuming its the new car. They are stuffing bucked loads of more stuff into the car in terms of sheer volume and then they make the car shorter? must be a boxy looking thing. Only l feeling i get on it is that there is less air for the diffuser due to no blowing at all. As well as perhaps fatty sidepods making it optimum with a shorter underside something something.

F1 cars all use the maximum wheelbase dimension allowed by the rules. And this wheelbase dimension is quite large in comparison to what you would see on a typical 4-door production car. The most likely reason for this is to maximize the underbody area available for creating aero downforce.
Can't imagine any logical reason a chassis designer would opt for using less wheelbase than the rules allowed.

What I am trying to find out is the difference between Lotus' short wheelbase and long wheelbase cars.
Are we talking 6", 2" or 1/2" for example?
The media are saying "shorter", but no one is saying by how much.
Inquisitive minds want to know

The increase in wheelbase is more like 10-12 cm. Since the front axle line is taken as a reference for the front wing & underfloor (T-tray), both those items are stretched by the same amount.
The extra distance behind the front wheels to the sidepods allows that air to 'settle' more before entering the rad ducts or spilling round the sides, giving gains.
The weight distribution edges towards the rear, which takes load off the front tyres, allowing better durability.
I think Raikonnen prefers the slightly more 'edgy' feel to the standard car whereas Grosjean's style complements smoother turn in characteristics.
Lotus will probably stick with the longer wheelbase next season. If they survive...

Whoops, duff information from my source. 10-12cm may have been the ideal target but would require shifting of chassis pick up points & thus great changes to the chassis. Just not practical half way through a season. (or legal?)
7.5cm would be about as far as you can go by angling the composite wishbones & not revising the chassis.
