The development work on the Lotus Evija continues at a fast pace with computer simulations and intense test sessions that were carried out in the United Kingdom and in Italy. The hypercar electric, the first of the factory in Hethel, is still in the process proptotipale and the responses that arise from the various tests, are decidedly enthusiastic.
To bring back some impressions of the last test is Gavan Kershaw director, attributes and product integrity of Lotus Cars, which drove the engineering prototype 2, the most advanced of the three in the test, with the suspension on a customer-specific, drive EV, brakes and carbon fibre bodywork.
“The car is currently in the pure state, without stability control, or torque-vectoring – said Kershaw – In this way, we can assess the fundamental components of the frame, for a point mass optimal mechanical before adding the electronics.
And is our method of working: get the key points right from the start and use the aerodynamics, the kinematics of the suspension and the geometry, to hear the response of the vehicle.
We have assessed the stability and the agility in tight corners. We performed fast acceleration to calculate the distribution of torque, and we examined the adherence and the response of the tyres”.
“Lotus has always been a question of “input = output”, so if you do something you get an answer, and this is what we are working now, " continued the inspector – it Is all a matter of details, and then, for example, we are confirming the progressive response of the pedals.
we Know that there is a huge amount of torque, but drivers will only when the will require with the right foot. It's about getting the right balance of accelerator.
We have assessed the steering angle with respect to the response of the vehicle at different speeds to ensure that the car is smooth at 30 as at 200 miles per hour”.
“Through test like this, we can work on each element, such as the way in which you feel connected to the car, the driving position, the location of the primary controls and visibility – has explained Kershaw – this Is to validate how the thousands of hours of computer simulations translate actually in the vehicle.
it Is a twofold process: to demonstrate that the objectives were correct and that the results are transferred accurately in the car. It is also to put the fruit of the experience acquired with other vehicles such as the Exige and Evora, the Lotus GT race, so that the Dna of the base of the Lotus is expressed at its best in the Evija”.
“For me it's really exciting, " concluded Kershaw – I Love this part of the development of any Lotus because it is proving that the mechanical design and the laws of physics that are behind it all are correct, and then work with our engineers to improve the experience and give the car a real character Lotus. It is the work step after step we take with every Lotus, and with Evija is not different”.
Needless to say, the smile that accompanied the face of the tester to the end of the test, an expression that says it all about the extreme performance of this supercar and power is the result of thirty years of experience at the wheel of the Lotus. (m.r.)
