Diesel supercar.

Trident, will display its all-new Iceni at Salon Privé 2012, held at West London’s Syon Park from 5-7 September. The Iceni’s uses Trident’s patented Torque Multiplication technology to deliver a claimed top speed of nearly 200mph and a 0-60mph time of 3.7 seconds. The Iceni is built to order in Norfolk and priced from £75,000.
A mid-front mounted 6.6-litre turbo-diesel capable of running on mineral diesel, bio diesel, palm oil and linseed oil delivers 430bhp and 950lb ft at under 3250rpm. An option to upgrade to 660bhp is also available, delivering 1050lb ft.
Linseed oil seems questionable to me as a fuel, it has a tendency to polymerise when introduced to high temperatures (like an engine), especially when sprayed as a mist.
General rule is that if it’s good for making varnish it’s terrible for making fuel.
