Emira 600 Clubsport Edition - JUBU gives the Lotus Emira supercar vibes!

I think 500 hp and 400 lb-ft would feel blistering in our cars. 600 hp would be overwhelming for me. Not that I wouldn’t be happily overwhelmed!

My main concern is the clutch/transmission/driveshafts. If I had all that extra power, I would want the driveline built so I could be as aggressive as I wanted with near 0% chance of breaking anything. Like at 600 HP, the driveline could actually take 750.

Even at the stock power levels, I don’t shift too aggressively, and I don’t think I’ve ever done a standing-start hard launch. The mechanicals just don’t feel sturdy enough to me to risk breaking expensive stuff.

The drivetrain on my 2006 Mustang GT, on the other hand, has taken years of “aggressive” shifting and hard launches without breaking a sweat. It doesn’t feel the most refined, but I have no real fear of breaking it.

For what it’s worth, I think you’d handle 600hp just fine.

600hp in a 3300 is ideal for a daily.

I agree 500hp is probably what it should have shipped with. The gt4 motor w the bigger blower makes 470, on same internals, w warranty. Would make a lot of sense..

I'd be more than happy with 450-475whp and a 7500 red line.

Well the power is easy. JB4 plus intake, maybe 3rd cat delete. Less than $2500, jb4 installs in 30 min. Intake maybe 30 min. 7500 rpm redline is a lot harder…

i'd be happy with less power but 8k redline

The issue is anything above 7200 rpms requires engine out. It’s much cheaper to hit 600hp than 8000rpms

Yeah I get it. Just doesn't help when the 2 cars I owned prior to the emira had 8k+ redlines.

I have the exact same situation and desire for rpms lol

Not sure about that. Jubu want £40k + VAT for 600bhp. I'm sure you could do it for less than that.

headers, 2.6 pulley, cams and an ecu flash w 7200 rpms redline oughta do it.

JUBU... As many have said, they’ve blow 5-6 of these motors. They truly are the world’s #1 destroyer of emira motors. Why would we use their circus pricing as evidence.

Jubu is sort of the Phillip plein of aftermarket brands.

But idk maybe they do know best and are well priced man.

Their build is engine out and new blower. Most of it is labor.

I cant comment on the quality of Jubus engine work having not had any personal experience but it does kind of reinforce my point that it shouldnt cost 40k to reach a 7500 rev limit and 40k does seem expensive for the extra power, but, nobody else is doing it that I'm aware of, certainly not in the UK.

I doubt every tuner is 100% clear on killing an engine and 5-6 is kind of dependent upon how many have they done. If thats 1%, its not significant. If its 50% then thats a whole different question. And then next thing for me would be what did they do about it when it happened. If they walked away, thats an issue. If they sorted it, its redeming.

I do know that most of their parts seem to be really good quality so if its just a question of the builder, get someone else to do it.

There’s info on what it takes to go over 7300 elsewhere don’t want to gum this up further. There’s also info on where Jubu gets their parts from

Feel free to DM me on their parts sourcing. Dont think I've seen that before.

The launch of the Lotus Emira in 2021 marked the beginning of a new era for the Hethel based manufacturer. With this car, the British brand went away from building its uncompromising radical, ultra-puristic drivers cars to manufacturing still exotic, but more mainstream sports cars. The OEM Emira comes as a well-balanced daily driver with many luxurious amenities. This helped Lotus to sell its cars to a broader audience, but it also came with some downsides: the more tamed Emira is heavier than its predecessors and does not provide the agility, dynamics, and emotion of former Lotus models. The Emira is a great sports car, but many fans of the brand still miss the ultra-agile, lightweight approach that Lotus cars were known for.

JUBU Performance, a car tuning company from Austria wants to bring back the original Lotus-vibes in the Emira and has now released their Emira 600 Clubsport. This special edition is lighter, more powerful and more agile than the Lotus base model, but -according to JUBU - still maintains all features and amenities of a modern daily driver supercar.

From sportscar to supercar.
Nothing stayed untouched to achieve an impressive overall performance of the Emira ClubSport. JUBU rebuilt the whole powertrain, reduced the weight of the car, improved aerodynamics as well as brakes, suspension and safety. According to JUBU the Emira ClubSport edition feels now more like a supercar than an exotic sports car.

High-performance powertrain
The Emira ClubSport comes with the well-known supercharged 3.5L V6 Lotus engine, but has undergone a major upgrade procedure. Basically all internals have been changed or reinforced by JUBU to be able to deliver 600 horsepower. To tame this brutal force, the car comes with a 6-speed HD gearbox or an optional 7-speed Dual Clutch system. JUBU also installs a Drexler LSD as well as a high-end dry sump lubrication system ex works. The powertrain control unit was developed in partnership with Syvecs engineering. To improve the weight distribution and the center of gravity, the engine in the Emira ClubSport is lowered and slightly tilted. Martin Jung, CEO of JUBU Performance: "This powertrain is based on over 20 years of experience and many of its components come straight out of our Pikes Peak winning drivetrain. Especially with the 6-Speed manual gearbox, the solely petrol-powered performance feels so much purer than anything you can get from one of these digital cars of our time."

Added lightness
According to Colin Chapmans mantra " Add lightness“, the Emira ClubSport is approximately 120kg lighter than an OEM LotusEmira. JUBU has exchanged many parts on the exterior and interior with ultra-lightweight carbon fibre components. This helps to improve the overall agility of the car massively. The (optional) forged magnesium rims help to reduce weight furthermore, especially on unsprung masses.

Advanced aerodynamics
In the 2,5-year development process, JUBU was also focused on improving the aerodynamics of the car. The Emira CS comes with an integrative aero pack, consisting of a massive front splitter, front canards, a redesigned diffusor and a 11-way adjustable swan-neck rear wing - all made of carbon fibre. The aero pack adds lots of downforce and also helps to improve the balance of the car. Martin Jung: "Our team spent lots of time with CFD-simulations and uncountable hours of testing on roads and tracks with different characteristics to find the perfect aero-balance for the Emira ClubSport."

Improved overall dynamics
To improve the overall dynamics, JUBU partnered with Ohlins to create a custom 3-way adjustable suspension, designed a cooled high-performance braking system and equips the Emira CS with Michelin Pilot Sport CUP 2 tyres.

Reliability & daily driving capabilities
The Emira ClubSport was designed to maintain all the daily driving capabilities of the OEM Lotus Emira. All comfort features stay untouched and the drivability for daily use on roads remain fully intact - but within the blink of an eye, the Emira ClubSport is ready for heading to the track and providing astonishing lap times. "The Emira Clubsport is pretty easy to drive, no matter if you cruise around the block, enjoy a mountain road or perform on track. All components are built to last and the car is pretty easy to maintain. It’s a real daily driver but also a spectacular arrive-and-drive tracktool.“, says CEO Martin Jung.

Variants
The Emira ClubSport Edition is available in a 530hp and a 600hp variant.

I was really excited to hear about the 600CS, and the performance difference but very deflated to see in the chart that it improves 0-62 times by 0.1 seconds. 3.9 instead of 4.0. Slower than our current M model family SUV. Is that accurate?

FlashingBlade · Jan 28, 2026

I think the quoted 0-60 (not 62) for 3.5 V6 manual is 4.5 so it would be a reduction 0.6. Its a lot of money for 0.6 gain IMHO but each to their own on that.

In terms of comparison to a BMW SUV, well, that will be automatic and AWD vs a RWD manual and that makes a big difference in a straightline drag. I daily a 2017 BMW 435d remapped to approx 380bhp and it can do 0-60 in 3.6 because its auto and RWD (all whilst averaging 44.2 mpg lol)

For me, if you want 0-60 figures, get a EV. The Emira is more for when corners are introduced which is why I'm not overly bothered about top end power. That said, I would like an extra 500-700rpm and I'd pay money for that over power hikes.

I am sure they are grossly underestimating the 0-60. If you add 200hp, expect to pick up more than 0.1s. Safe bet city

You’re right. I did go to the website and the manual v6 is 4.3sec 0-62. I’d love to see the result with the auto trans. That’s amazing mileage and performance from the BMW d. My SUV is an X4M. With remap and extras is right at 730hp, and 3.0 sec flat 0-60. That why the 3.9 in a sports car this light felt conservative. The manual for sure contributes as you said.
I’m and Aussie in the US and saw my first Emira the other day. It looked so good. As a newly to the thread and the car I see reference to the motor being a Toyota Camry 3.5, and others saying Lotus engine. Any clarity?

I would have to think so. I double checked the website and manual is 4.3 sec standard spec and auto is 4.0. But the 600cs is a big investment and hp gain for a very small performance change. That power to weight just doesn’t add up? Id hate have to tell my car buddies with less hp and heavier cars to “wait up, lets see who is faster through this corner - and put all my bragging-rights eggs in that basket”. Still a huge fan of the aesthetics but just wanting to understand what’s going on here.

I have an m850i it’s awd, automatic, and twin turbo v8. Monster torque right off idle. Of course it’s faster off the line.

Faster around road course? Hell no.

My buddies emira is up 100hp already, will soon be up 150.

It feels faster than our c8 did the line.

Stay tuned (pun intended)

I wouldn’t stress what your buddies think.

Dm me if you want to talk candidly about adding power to emira

Lotus have a tradition of using engines from other manufacturers, they've nearly always done this and instead concentrated on the chassis and handling - the last Lotus designed engine was in the Esprit in 2004.

The Emira V6 is a Toyota sourced engine (it's like the Camry engine but very much tuned), the Emira i4 is a engine from AMG.
