Lotus is returning to its core strength: building lightweight, powerful sports cars with petrol engines. The latest iteration, the Emira 420 Sport, is the most focused version of the Emira yet, and Lotus claims it’s now the world’s fastest four-cylinder production car, capable of hitting 186 mph. That claim needs scrutiny—its engine, a Mercedes-AMG A45 S unit, officially tops out at 168 mph—but the Emira 420 Sport still delivers more power, sharper handling, and a more aggressive stance than its predecessors.
The Emira 420 Sport starts at over £100,000 with no options, and adding the optional Lightweight Handling pack pushes the price closer to £113,000. For that, you get a car that feels like a modern Lotus—firm, precise, and dialed in for both track and road. But it’s not without compromises. The seats remain too high and not grippy enough, and the dual-clutch gearbox, while smooth, lacks the mechanical engagement of a proper manual or even some rivals’ automatics.
More power, less weight, same soul
The Emira 420 Sport keeps the same 2.0-litre Mercedes-sourced four-cylinder turbo as the Emira Turbo and Turbo SE, but with 416 bhp and 369 lb-ft of torque—identical to the A45 S it’s based on. The difference is in the tuning: sharper shifts in the eight-speed dual-clutch gearbox shave 0.2 seconds off the 0-62 mph time, bringing it to 3.9 seconds, faster than the V6-powered Emira variants.
Lotus has stripped weight aggressively. The standard model tips the scales at 1,455 kg, but with the Lightweight Handling pack, it drops to 1,430 kg. The pack removes 25 kg—mostly from the rear, via a titanium exhaust, carbon-fiber louvres (replacing the rear window), and a lithium-ion battery. The Multimatic adjustable dampers and forged alloys further reduce unsprung mass, improving agility.
Aerodynamic tweaks, like a revised rear spoiler and front splitter—add 25 kg of downforce without increasing drag. The car sits 5 mm lower, new wheel arch vents improve cooling, and the side scoop behind the door directs airflow more efficiently. The blue-tipped titanium exhaust (part of the handling pack) is the most obvious visual upgrade, a nod to Lotus’s racing heritage.
Track-focused, but not track-only
The Emira 420 Sport was tested at Hethel, Lotus’s UK headquarters, where its strengths became clear. The electrically assisted hydraulic steering feels precise, the brakes—now fed by improved airflow, are exceptionally responsive, and the chassis balances cornering grip with a light, flickable feel. Trail braking is effortless, thanks to the car’s low weight and well-tuned suspension.
Yet the dual-clutch gearbox remains the weak link. While it handles easy shifts well, it lacks the sharpness of a proper manual or even some rivals’ paddle shifters. Shift up in the Emira above 6500rpm and you run into the soft limiter, which stalls progress as the engine and gearbox sort out their differences. I’d prefer a much harder cut, right on the red line, giving you a sense that you can take the car to the limit. In the Emira, you always hold back slightly. It does easy auto changes very nicely, but not the more thrilling, whip-crack ones you want when it’s in track or sport modes.
Inside, the build quality has improved dramatically since Lotus’s older models. The carbon-fiber paddle shifters are longer, the body-colored trim adds a touch of sportiness, and the materials feel premium. But the seats, still too high and not supportive enough, are a letdown. Lotus acknowledges this, noting that redesigning them for better fit would require costly homologation.
The optional sunroof adds drama because of all the extra wind and engine noise you get, but the difference isn’t the life-changing moment like on the Porsche 911 GT3 S/C. The Lightweight Handling pack, however, is worth it. Without it, the car feels heavier and less refined. With it, the Emira 420 Sport becomes a proper lightweight, its agility and balance sharpened.
The ultimate geek-out/pub ammo change is the blue tip to the exhaust, spot that and you know you’re looking at a 420 Sport. This is now titanium, or at least it is if you spec the lightweight handling pack, saving 9kg.
So although it performed well at Hethel, it didn’t feel like it was sacrificing too much road ability for that track experience.
The bigger question is whether it’s worth over the Turbo SE. For enthusiasts who prioritize speed, handling, and exclusivity over cost, it’s a strong choice. For everyone else, the price, and the gearbox’s limitations, might hold them back.
The Emira 420 Sport isn’t perfect, but it’s the best Lotus has done in years. It proves the brand can still build a car that’s both a throwback to its racing roots and a modern, capable sports car. Whether that’s enough to convince buyers remains to be seen.
