For the Lotus Evora 414E Hybrid Concept, Lotus Engineering has developed a highly efficient, high performance drive-train system consisting of twin motors each limited to providing 152 kW (207 PS/204 hp) of power and 400 Nm (295 lbft) of torque to each wheel via independent, single speed, reduction transmissions integrated into a single housing, enabling torque vectoring dynamic control of the vehicle.

The vehicle energy storage system is made up of the latest Lithium Polymer battery chemistry providing 17 kWH energy storage capacity. The battery pack is optimized for energy density, efficiency and high power demand, with over 100 kW discharge capability.

The Lotus Range Extender engine provides 35 kW (48 PS/47 hp) of power at 3,500 rpm via the integrated electrical generator and features an innovative architecture comprising an aluminum mono-block construction, integrating the cylinder block, cylinder head and exhaust manifold in one casting. This results in reduced engine mass, assembly costs, package size and improved emissions and engine durability. The engine uses an optimized two-valve, port-fuel injection combustion system to reduce cost and mass and can be operated on alcohol-based fuels and/or gasoline. The generator converts mechanical energy to electrical energy to replenish the battery pack charge and provides additional vehicle range in a small light weight package. The generator is also used as a motor to start the range extender engine. The low mass of the range extender unit (85 kg) and compact package makes it ideal for the series hybrid drive-train in the Lotus Evora 414E Hybird.

The Lotus Elise introduces the new 1598 cm3, 1ZR-FAE engine, provided by Toyota. The key to this engine’s performance and efficiency is the Valvematic system (a variable valve lift mechanism), which is combined with the dual VVT-i (Variable Valve Timing-intelligent). The engine continuously controls intake valve opening/closing timing and the intake valve lift to vary the volume of the intake airflow, giving significant improvements in efficiency and fuel economy. This ensures optimal performance based on the engines operational condition, thus helping the Lotus Elise achieve both high fuel efficiency and high performance.

First of all, the maximum power output is achieved at near maximum revs (engine speed) of 6800 rpm and maximum torque (a respectable 160 Nm, 118 lb.ft) is reached at 4400 rpm. This gives a good combination of mid range pull but also encourages the driver to rev the engine to the maximum permitted engine speed of 7000 rpm (transient rev limit). Like all Lotus Elise sportscars, there are three shift up lights, on the binnacle cumulatively lighting when the driver is getting closer to the rev limiter and when all three are illuminated, they flash to indicate that the driver is almost on the rev limiter so time to change up a gear!

The Lotus Evora’s chassis is an evolution of the Versatile Vehicle Architecture (VVA) from the Lotus APX concept vehicle previously showcased at the Geneva Motorshow, and allows for the development of a range of vehicles up to a gross vehicle weight of 1,900 kg. This architecture has been designed to be more applicable to mid-volume applications by utilizing our low capital investment manufacturing processes. The Lotus Evora structure progresses the Lotus ‘bonded and riveted’ technology used in the Elise family of vehicles with unique extrusions and folded panels, whilst providing contemporary ease of ingress/egress, build modularity and improved, lower cost repairs.

The Low Volume VVA architecture has been designed so that it can be extended in width, length and height. The strength and stiffness of the low volume VVA chassis can be modified cost effectively by varying the wall thickness of the extrusions, without altering the exterior dimensions. The ability to lengthen or shorten extrusions with the option to tailor the chassis stiffness, vastly increases the number of vehicles that can be developed from this vehicle architecture. Front and mid engine installations have been considered, as well as hybrid and Electric Vehicle (EV) applications.

The Lotus Exige S Type 72 celebrates the most successful F1 car of all time, the Lotus Type 72 Formula One car, which achieved 20 Grand Prix victories between 1970 and 1975.

The Lotus Type 72 was driven by such Lotus greats as Jochen Rindt, Emerson Fittipaldi, Ronnie Peterson and Jacky Ickx and won three Formula One Constructors’ Championships (1970, 1972 and 1973) and two Drivers’ World Championships (the first being won by Jochen Rindt in 1970 and the second by Emerson Fittipaldi in 1972).

The colour scheme of the Lotus Exige S Type 72 commemorates the famous and easily recognisable black and gold Lotus Type 72 livery and is finished by the same sign writer who painted racing cars for Team Lotus.

Performance through light weight has long been a Lotus philosophy. The 935kg Lotus Exige S Type 72 sprints to 60 mph in just 4.5 seconds and to 100 km/h in 4.7 seconds, before reaching a top speed of 145 mph, 233 km/h. The Lotus Exige S Type 72 also offers class leading fuel economy and emissions, with fuel economy of 6.5 litres/100 km (43.5 mpg) on the Extra Urban Cycle and CO2 emissions of 199 g/km.
