Lexus (Toyota) makes a 4.3 liter motor, currently putting out 300 HP and 325 torque. Lotus could do their magic on it and get 400-450 HP out of it. And if the Esprit replacement comes in no heavier then 1150Kg (2500 LBS).
Crossposting - against the rules. Since the general impression is the new car will NOT be carrying the Esprit name - I will lock this one and leave the post in General Lotus...
