Lotus says the new Emira 420 Sport is the world’s fastest four-cylinder production car, supported by a 186-mph top speed. The more interesting part is how Lotus reached it. This is a focused, mid-engine sports car extracting serious pace from a turbocharged 2.0-liter four-cylinder.

The engine produces 416 bhp and 500 Nm of torque, sending power to the rear wheels through an eight-speed dual-clutch transmission. Lotus quotes 0–60 mph in 3.7 seconds, 0–200 km/h in 12.47 seconds and a standing quarter mile in 11.91 seconds. Those figures put the Emira 420 Sport firmly into modern supercar territory, even if its cylinder count sounds more hot hatch than exotic.

The Emira 420 Sport is available to order now, with deliveries expected from August 2026. U.S. pricing begins at $122,900. Lotus is not presenting this as the affordable Emira. It is the lightest, most powerful and most aerodynamically capable version of the car.

Why the Lotus Emira 420 Sport Is So Fast

The official specifications show that power is only one part of the equation. Output rises by 16 bhp over the Emira Turbo SE and 56 bhp over the Emira Turbo, while revised transmission calibration is intended to produce faster, more intuitive shifts. In-gear acceleration from 80–120 km/h takes 2.4 seconds, which may matter more on a real road than the headline top speed.

The 420 Sport also sits 5 mm lower than a standard Emira and uses a dedicated sports chassis. Revised suspension geometry is designed to sharpen turn-in and improve body control. The optional Lightweight Handling Pack adds two-way adjustable Multimatic dampers, allowing compression and rebound settings to be tuned independently for road or track use.

Lotus has increased cooling capacity, with 15 percent more airflow to the radiators and a 30 percent increase through the exhaust-valve area. Removable brake-duct panels and the front license-plate mount provide additional cooling for track driving.

Lotus Makes Speed by Removing Weight

Lotus has spent decades arguing that less mass can be more valuable than more horsepower. With the Lightweight Handling Pack, the Emira 420 Sport can shed up to 25 kilograms, or about 55 pounds, compared with the Emira Turbo.

A titanium exhaust removes weight from the rear, while a carbon-fiber louvered tailgate replaces the standard glass panel. The tailgate lowers weight high in the body and helps release engine-compartment heat. It also recalls earlier Lotus models, including the Esprit Turbo.

Aerodynamic changes add 25 kilograms of downforce without increasing drag. A revised front splitter, wheel-arch vents, extended side sills, enlarged intakes and a longer rear lip spoiler improve stability and cooling. The result is not simply a faster Emira in a straight line. It is intended to remain composed when speed, heat and repeated hard use test the chassis.

What $122,900 Buys—and What It Means

Standard equipment includes new 20-inch forged alloy wheels, dark-tinted rear lamps, carbon-fiber shift paddles and unique 420 Sport treadplates. Buyers can add exterior and interior carbon-fiber packages, hand-painted coachlines and a removable tinted glass roof. The Michelin Pilot Sport Cup 2 tires underline how seriously Lotus expects owners to approach track driving.

There is still a practical question behind the impressive numbers. A $122,900 four-cylinder Lotus enters a price range filled with powerful six- and eight-cylinder alternatives. Buyers must value steering feel, low mass and chassis response more than engine size or badge recognition.

That is what makes the Emira 420 Sport interesting. Lotus has not copied the usual supercar formula. It has taken a compact engine, reduced mass, added useful downforce and tuned the car around driver involvement. The 186-mph claim will earn attention, but the real achievement may be proving that four cylinders can still feel properly exotic.
