McLaren MP4-26 - L-shaped sidepods

There is no doubting the new MP4-26 is very different from all the other 2011 cars. Technical director Paddy Lowe has exploited to the extreme the idea of higher outer sidepods, last seen on the likes of Benetton's B195 from 1995 and Ferrari's F310 from 1996. The aim is to clean up and better direct the airflow to the beam wing at the rear of the car, an area now even more important thanks to the ban on double diffusers. This solution also gives McLaren the possibility of running Renault-style forward exhaust exits.

Renault R31 - forward exhausts

Renault are no strangers to radical exhaust solutions, having launched a design that blew on to the diffuser with the RE30 at Monaco in 1983, and side-exit exhausts on the RE50 in 1985. This season the exits are low down, just in front of the sidepods, in order to accelerate the airflow to the rear diffuser. They are angled backwards slightly, with a very long pipe length designed to minimise the torque and power handicap that comes with the unusual positioning.

Red Bull RB7 - revised exhausts

Red Bull rolled out the RB7 at Valencia and by the end of the test had already added a new solution to the new car. Longer exhaust pipes (inset), blowing on to the external section of the diffuser's side channel, replaced the standard design seen on the first day.

Red Bull RB7 - exhaust positioning 23 February 2011

At the very first test in Valencia Red Bull introduced a new blown exhaust layout. The long flat pipe blows into the area just in front of the rear tyres (see red arrows). In this section (highlighted in yellow) the underbody has been cut away so that the air can blow directly under the side channels of the diffuser. This solution appeared to have been copied by Force India at the most recent test at Barcelona's Circuit de Catalunya.

Toro Rosso STR6 - double floor arrangement

In a solution not dissimilar to that seen on 1992's Ferrari F92, Toro Rosso's 2011 car has raised sidepods to create a second venture channel in order to achieve extra downforce. This is combined with quite long exhausts, with flat exhaust exits (red arrow) towards the rear of the car.

Williams FW33 - innovative rear packaging

15 February 2011

The Williams FW33 has the lowest rear end (2) of all the new cars - lower even than Red Bull's RB7 - due to very compact packaging of the gearbox and differential. So low are they in fact that the driveshaft (3) angle is the greatest ever seen, at around 14° (6-7° is normally considered the maximum limit for this component). Williams spent a lot of time developing and testing this solution before introducing it to the new project. Indeed, the whole rear of the FW33 is innovative - witness the unique pick-up point for the suspension's top wishbone, mounted directly on the central rear wing pillar (1). Williams have also followed the trend for a pull rod rear suspension layout for 2011. Only Ferrari, Sauber (with the Ferrari gearbox), Virgin and HRT have kept a push-rod layout.
