BTW, as you knew the Elise chassis is made from aluminium extrusions, read further a copied post :

Bearing in mind there are variations in how chassis stiffness is measured, this link
http://www.germancarforum.com/test-data/12334-list... gives some interesting and credible data and also suggests that plenty of steel and aluminium cars are much stiffer than the McLaren. That is not to say better in strength to weight, ability to package the structure around the occupants/mechanicals, or even crash performance. But perhaps stiffer. If I find the data for Bristol I will post it, but if you accept the figure of 13,500 Nm for the Mac it is not unreasonable for a car with a heavy gauge steel chassis and improved loading shared by the roof pillars (603 vs previous Bristols, but pre-Fighter) to achieve or surpass this stiffness. Many mass produced steel monocoques are now indisputably much much stiffer than 13,500 N/m.
Anyhow and OT, apart from the fact that McLaren wanted to build a landmark car that reflected contemporary Formula 1, the F1 could never have been built from aluminium. Ally differs from carbon in it's fatigue response; Bugatti learned as much when they were developing the five aluminium EB110 prototypes and found that the aluminium chassis lost 20% of it's torsional stiffness after 30,000 km testing - hence the carbon production car. (That Bugatti was a very thoroughly developed car, the quote about the chassis stiffness is again from EVO, March 2005). The drop off in performance with fatigue would not have been acceptable to GM"
