The British automaker’s Motorsport division has taken the Evora GT4 Endurance and evolved it into the Enduro GT Concept, which according to them, will be the base point from which the GT2/GTE homologated cars (for FIA and ACO) will be built.
Powered by a mid-mounted 4-litre DOCH V6 VVT-i engine, naturally aspirated and tuned by Cosworth, the Lotus Evora Enduro GT Concept develops 440 bhp @ 7,000 rpm and 460 Nm of torque @ 5,500 rpm. A sequential 6-speed transmission sends power to the rear wheels, while other motorsport specific  components fitted on the Lotus Evora Enduro GT Concept include a twin plate sinted clutch, a competition thermally coated exhaust manifold and a performance air filter.
The car’s chassis is made from aluminium,  while its suspension is a double wishbone with Ohlins dampers, coaxial coil springs and a uni ball wishbone joint.
The Lotus Evora Enduro GT Concept runs on 18 inch forged alloys wrapped in 24/64-18 – 27/65-18 tires front and rear, and uses a performance brake system with 22 mm race pads, two piece aluminium belled discs and 6 piston callipers at the front and 4-piston calliper at the rear.  
Complete specifications for the Lotus Evora Enduro GT Concept are available below the jump.
