More Than 360hp!? Lotus Emira 2.0T Dyno Test Review (1st 2.0 Dyno Test)

Lotus Emira 2.0T Dyno Test Review​

Test Conditions and Background
Test Vehicle: Lotus Emira 2.0T
Ambient Temperature: 20°C
Vehicle Modifications: Completely stock
Testing Location: HKS Performance
Number of Runs: 3
Measured Power: 334hp @ 6670rpm
Dyno Graph: Attached

Test Video

The aim of this test was to evaluate the Lotus Emira equipped with the AMG M139 engine in its completely stock form, particularly to see how well it performs compared to its claimed output of 360hp. Additionally, it was an opportunity to gauge the consistency of the power delivery.

---

Test Results and Observations
Across three runs, the measured wheel horsepower was remarkably consistent, peaking at 334hp at 6650rpm. The maximum torque measured was 37.87kg-m at 2900rpm. For a stock vehicle, this is an impressive showing. Considering drivetrain losses are typically in the range of 15-20%, the engine’s actual output is likely in the ballpark of 380-400hp, which is higher than the conservative 360hp figure quoted by the manufacturer.

The owner of the performance shop also noted that AMG engines are often conservatively rated, and this test result aligns with that reputation. Lotus has clearly optimised the M139 engine for the Emira, ensuring not just powerful performance but also excellent stability and consistency in its output.

0-100 km/h Acceleration Test
To further evaluate its performance, I conducted a 0-100 km/h acceleration test. Using the Launch Control mode, the Emira clocked a best time of 4.3 seconds, which matches the factory-claimed figure. However, as the tyres were not fully up to temperature, there was slight wheel hop during the launch. With optimal tyre conditions and a warmer surface, I believe the car has the potential to achieve closer to 4 seconds flat.

---

Conclusion and Verdict
The Lotus Emira 2.0T is undoubtedly a finely balanced machine that delivers both performance and driving enjoyment. In its stock form, the AMG M139 engine provides strong, consistent output, with wheel horsepower and torque figures that are highly competitive. Combined with Lotus's legendary chassis tuning, the driving experience is truly exhilarating.

What sets the Emira apart is not just its outright power but its poise. Whether accelerating in a straight line, carving through corners, or cruising at high speeds, the car feels planted and inspires confidence. For enthusiasts, it’s a machine that brings the concept of "man and machine as one" to life. For the average driver, it offers an engaging yet approachable experience.

Should there be an opportunity to explore performance upgrades in the future, I have no doubt this engine holds untapped potential, which is an exciting prospect for enthusiasts.

The power output from the engine is detailed in the VIN. This is the way to verify if your engine is a 360 or 400bhp version.

What is your VIN?

It should read something like SCCLEKKxxRHMxxxxx

x denotes a don't care.

That's reflected in the responsiveness. There's virtually no turbo lag. It's noticeably more immediate than my RS3, which is no slouch!

So how can you tell ?

Any instructions to tell which variant it is according to the VIN?

Yes, the 7th letter from the left is a K, denoting 360bhp. If it's an M, this is a Chinese Emera with 400bhp.

Is your 's a K or M?

It's a K, 360hp version.
So far, 400hp version only available in China and US markets.

Nice. Did they give you a version of the graph with the boost curve on it? Usually on a Dynojet there's a sensor they can T into one of your vac lines to give the additional info. On any dyno, actually, but I know for sure the standard Dynojet sensor package comes with one.

I'll check tomorrow

And....the purpose to run this dyno test....

Wait for my next post....

Now this is how testing is done and claims are established.
Out of all the 'performance' enhancements on the market today for the Emria AMG this one has the biggest opportunity for HP gains; IMO. Bet you pickup 10-15 HP.
Good luck !
