Heikki Kovalainen’s McLaren was at the bottom of the testing times today, 2.6s slower than Nick Heidfeld’s BMW.
McLaren haven’t shown much pace in the pre-season build-up so far, and speculation abounds as to whether the MP4-24 is a dud, or whether they’re ‘sandbagging’ to fool the opposition. Let’s put the theories to the test.
The ‘they’re just slow’ theory
After the MP4-24 hit the track for the first time murmurs from Woking suggested the car producing more drag than computer simulations had suggested it would.
The sight of McLaren mechanics conducting flow-vis tests (applying liquid to the car to study how the air moves around it at speed) fuelled suggestions that what they expected from the new car and what they got were not in agreement with each other.
On top of that McLaren have spent most of the tests so far using a 2008-specification rear wing. Was this because of some defect in the 2009 design?
This could be a huge and fundamental setback for the team of the type that plagued Renault in 2007 – the team went from world champions one year to non-winners the next.
The ‘they’re sandbagging’ theory
The problem with testing is it’s hard to find out what each team is doing, and how much fuel they’re running with. At F1 Insight yesterday Steven Roy had heard a rumour that Kovalainen was persistently backing off to avoid setting quick times in Spain.
The theory that McLaren were hiding their pace is bolstered by a story on Autosport drawing attention to McLaren’s radical new floor arrangement (not shown in the picture above). Craig Scarborough explains:
A triangular section of floor is missing between the forward part of the floor, which follows the curve of the sidepods, and a squared off edge just ahead of the diffuser. […]
A diffuser creates its downforce at two points: firstly at the kick-line between the diffuser/floor, then secondly at its leading edge. By effectively moving this leading edge backwards, McLaren are also moving the downforce it creates towards the rear. This may be part of a McLaren strategy to focus downforce production on the front wing and diffuser, as both devices are efficient at creating downforce with little drag.
This in turn could explain why McLaren have been using their 2008 wing for so long. The team had said they were using it to ‘simulate 2009 downforce levels': so perhaps they were expecting to get a lot more downforce from the final configuration including the shaped rear floor and final specification rear wing?
Lewis Hamilton will be hoping it’s the latter – or his world championship title defence might not last very long.
Are McLaren stealthily playing down the performance of their car? Or are they set for another uncompetitive season as they had in 2004 and 2006? Share your thoughts in the comments.
