Specification

Project N2 follows in the footsteps of project N1, our Duratec converted S1 Motorsport Elise. Project N2 is based on a Toyota engined Lotus chassis, and is a ground up build to showcase Nitron’s products, but also to demonstrate our depth of understanding of Lotus products.

Project N2 will aim to be the quickest production Lotus Exige ever made, and not only have we selected the very best components for the car to enable us to do this, we will also apply all of our resources to make this package work properly as race cars should. We will have a full set of data-logging permanently fitted to the car, and using the top level MoTec analysis software and our other testing equipment we will be able to hone this car to perfection.

The car will be essentially a GT car for endurance racing, but will be devastatingly quick even on a short sprint race. Once completed we will take the car to the US and Japan to visit all the most famous tracks and demonstrate our engineering prowess and the range of Nitron parts from which the car has been made.

The following specification is not exhaustive but gives a good idea of the very high standard the car will be prepared to.

  1. Beautiful. Well written also. Made me smile seeing you using the heated windshield technology like what Gordon Murray resourced/found for the F1. I am very much looking forward to reading all you have shared/documented . Well done !

    I am in the process of purchasing a late model S2 Exige . Your suspension and many other parts will find a home soon.

    My business is selling Hi Tech Aviation grade wire , cable and sleeving.
