The Lotus Exige III S Coupe Cup R 3.5 V6, produced between 2013 and 2015, represents a focused, high-performance iteration of the Exige III S Coupe. Positioned as a track-day oriented variant, the Cup R model was designed to bridge the gap between the road-going Exige S and the full-race Exige R. It built upon the already lightweight and agile Exige platform, adding significant power and track-focused enhancements. The Exige III series, internally designated as the A122 platform, continued Lotus’s tradition of providing a pure driving experience, prioritizing weight reduction and handling above all else. This particular variant aimed to deliver a near-racecar experience in a road-legal package.

Powertrain & Engine Architecture
The heart of the Exige Cup R is the 3.5-liter supercharged V6 engine, derived from the Toyota 2GR-FE family. Lotus extensively modified this engine, adding an Eaton supercharger and an intercooler to significantly boost power output. The engine features a dual overhead camshaft (DOHC) valvetrain with variable valve timing (VVT-i) on both intake and exhaust camshafts, optimizing performance across the rev range. Multi-port fuel injection ensures precise fuel delivery. The engine’s mid-engine, transverse layout contributes to excellent weight distribution and handling balance. The 6-speed manual transmission, sourced from Hewland, is known for its robust construction and precise shift feel, crucial for maximizing performance on the track. The transmission’s gear ratios are optimized for acceleration and track use, with closer ratios than the standard Exige S.
Driving Characteristics
The Exige Cup R delivers a raw and engaging driving experience. The supercharged V6 provides a substantial surge of power, with peak torque arriving at 5000 rpm. This translates to strong acceleration throughout the rev range. The lightweight construction (approximately 2293 lbs) and well-tuned suspension contribute to exceptional handling. The car feels incredibly responsive to steering inputs, providing a direct connection to the road. Compared to the naturally aspirated Exige S, the Cup R offers significantly more power and a more aggressive driving experience. While the Exige S is more approachable for everyday driving, the Cup R is clearly focused on performance. The manual transmission requires skilled operation to extract the most from the engine, but rewards the driver with a highly involving experience.
Equipment & Trim Levels
The Cup R trim level was purposefully minimalist, prioritizing weight reduction over luxury. Standard features included lightweight composite body panels, a stripped-down interior with racing seats, and a roll cage for added safety. Air conditioning and a stereo system were typically omitted to save weight. The interior featured Alcantara trim and carbon fiber accents. Optional extras included upgraded suspension components, data logging systems, and racing harnesses. The focus was on creating a car that was ready for the track with minimal modifications.
Chassis & Braking
The Exige III S Coupe utilizes a lightweight, bonded aluminum chassis, providing exceptional rigidity and strength. The suspension features fully independent double wishbone suspension at both the front and rear, with adjustable dampers and springs. This allows for precise tuning of the suspension to suit different track conditions and driving styles. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. The ABS system helps to maintain stability under hard braking. The Cup R variant often featured upgraded brake pads and rotors for improved fade resistance during track use.
Market Reception & Comparison
The Lotus Exige III S Coupe Cup R 3.5 V6 was well-received by automotive journalists and enthusiasts alike. Critics praised its exceptional handling, powerful engine, and raw driving experience. It was often compared favorably to other track-focused sports cars, such as the Porsche Cayman GT4 and the Chevrolet Corvette Z06. However, the Exige’s minimalist interior and lack of creature comforts were noted as drawbacks for some. Fuel economy, while not a primary concern for this type of vehicle, was reasonable given the performance on offer. Reliability was generally good, although the supercharged engine required regular maintenance.
Legacy
The Exige Cup R remains a highly sought-after vehicle among Lotus enthusiasts and track-day drivers. The 3.5-liter supercharged V6 engine has proven to be a robust and reliable powerplant when properly maintained. The car’s lightweight construction and exceptional handling continue to make it a formidable performer on the track. In the used car market, the Cup R commands a premium price due to its limited production numbers and desirable specifications. It represents a high point in Lotus’s commitment to providing a pure and engaging driving experience, and continues to be celebrated as a modern classic.
