Ovanlig och rolig liten bil. Liten och lätt aluminiumkaross, låg luftmotstånd, liten motor, elbyhrid, E85 och DAF/moppe CVT!

Citat:
The Oaktec Insight has three factors that make it unique in the world of special stage rallying. Firstly it uses an electrical hybrid system to capture energy that would be wasted during braking and retardation, and re-uses it to help accelerate the car by providing current to an electric assist motor. Secondly it has been developed to use renewable E85 bio-ethanol fuel in place of conventional unleaded petrol. This fuel gives strong power combined with ultra low emissions. The third factor that makes this car highly unusual in motorsport is that its hybrid power system drives through a continually variable automatic transmission, which gives the car better performance and driveability.

“We have been very pleased with the performance of the car which is still at a very early stage of development. We already have the straight line speed to match the highly developed lightweight class B Formula 1000 cars. We have great optimism that we can seriously ruffle some feathers when we try the new developments to the hybrid system in 2007.”

The team have achieved success in 2006 without altering the low emission outputs of the standard Insight, which project engineer Andrews explained would have made the project less impressive.

“This project would have less significance if we cheated with the emissions and vehicle efficiency,” he said. “It would be very easy to get more horsepower from the lightweight three cylinder Insight engine by running richer mixtures at higher revs and removing the catalytic converters, but this would destroy the CO2 emissions record of the car which are currently the lowest recorded by a UK market production car at 85g/km.

“We believe our car to be even below this figure when using the bioethanol fuel blend and we will be doing tests to prove this soon.”

According to the rules, the car has to be 1,000 cc or less, with no form of sequential gearbox. It has to run on pump gasoline. Cars can be boosted with a turbocharger or a supercharger, and tires and suspension must conform.

OakTec followed those rules, but the organizers do reserve the right to make changes based on season events. The organizers asked, and OakTec complied.

The hybrid Honda Insight is a technical marvel, with a high-strength, lightweight aluminum body and one of the lowest coefficients of drag in the industry. OakTec partnered with Lotus Engineering for the car, which currently has a curb weight of just 1,829 pounds. More powerful batteries were added, and the hybrid system was tuned to recover more energy during deceleration and give more power when taking off. The car uses a continuously variable transmission and runs on E85 fuel.

Hade inte Honda bestämt sig för att lägga ner Insight? Vinnande koncept kanske, men Honda tjänade inte tillräckligt med pengar på bilen.

Jag har faktist ingen aning om nuvarande Honda Insight men denna "lilla" 3-dörs Insight byggdes 1999-2006.

Det är nog (för) dyrt att bygga bilar i aluminium jämfört med stål, hybriddriften kostar naturligtvis också extra.
