Key Takeaways Video – BMW i8 Speed and Performance
Update:
There have been no new versions of the BMW i8 released between June 2020 and now. (January 2025). The BMW i8 was discontinued in June 2020, with the last model being the 2020 BMW i8. Since then, BMW has not introduced any new versions or updates to the i8 model line.
The BMW i8 is a plug-in hybrid sports car that was in production from 2014 to 2020. It was known for its futuristic design and innovative hybrid powertrain. BMW has since shifted its focus to developing new electric vehicle models rather than continuing the i8 line.
Is an i8 a supercar?
There are supercars and then there is the BMW i8 which looks the part but there is an argument it is not actually a supercar. Make no mistake, the BMW i8 is exceptionally designed and is one of the fastest production cars ever built.
It certainly looks the part, as if it has just touched down from a few decades into the future which you would expect when one of its concept cars was featured in a Mission Impossible film.
BMW i8 0-60 MPH in 4 seconds – really!
This is because it uses a revolutionary new powertrain called Efficient Dynamics which provides instant torque and zero emissions.
While that initial acceleration from 0-60 MPH is undoubtedly impressive, how it hits its top speed is truly stupefying. Although it looks very futuristic and may be designed for those who really want to flaunt their wealth, you may have trouble getting your hands on one.
The Performance of A BMW i8
A supercar should come equipped with a high performance and the BMW i8 is no different. What you should note is that the engine is one taken from a mere 1.5 liter MINI Cooper.
That’s right, a three-cylinder MINI Cooper. Once you realize that, the performance can seem like some form of magic, something that has to be experienced to be truly believed.
There are some modifications that you would come to expect but the hybrid combination is something to behold.
That electric power amounts to an 11.6-kWh lithium-ion battery and a range of just 25 miles on the battery alone yet 320 miles in total for the gas.
Is BMW i8 faster than Tesla?
Both the BMW i8 and Tesla cars have software speed limiters, so the BMW is faster at 155 mph compared to the Tesla’s top speed of 130 mph.
As a hybrid, you still have to figure in the gas tank and this one holds 11.1 gallons and is 69 miles to the gallon when the two power sources are combined.
For torque, you are looking at 420 pound-feet which equates to 569 Newton-meters.
That power is routed to every wheel via the eight-speed automatic gearbox. Such distribution when you put your foot to the ground can feel seriously powerful but then you would expect that in such a well-made hybrid.
However, there are reports that the i8 suffers from light steering that has been marked in several BMWs.
That is something to consider in a car that is intended to come with sporting intent so there is an expectation of more feedback. Despite that torque, any bumps in the road can be felt but not too harshly.
The Speed of A BMW i8
The torque can pack a punch but what you really want to know is how that translates into speed which can be demonstrated in the horsepower. That three-cylinder engine can hit 231 BHP and the electric motor adds a further 143 BHP and all that adds up.
With a lightweight frame, the car has a top, limited speed of 155 MPH which is typical of BMWs. In fact, if you wanted that top speed, you could simply get a BMW M but why would you with such economy on offer from a hybrid?
BMW i8 top speed without limiter
Top speed is estimated to be over 160 mph without the limiter.
Other tests do offer more of a picture of just how quick the BMW i8 can be. From 62 MPH (100 KPH) to 124 MPH (200 KPH) in just under 11 seconds is seriously impressive. That the i8 can do 0-124 MPH (0-200 KPH) in 15.38 seconds is also quite a feat.
BMW i8 top speed km/h
Though it has that electronically limited maximum speed of 155 MPH (250 KPH), it can reach that in around 34 seconds. When you consider that the i8 is over seven years old with a 1.5 liter, three-cylinder engine, it sounds even better.
The History and Evolution of the BMW i8
Once upon a time, electric and hybrid cars were thought of as quite functional. They would do a job yet still feel dull. That all changed when some of the leading car manufacturers jumped on the bandwagon to shake things up.
One of those manufacturers was BMW who launched the i8 in 2014. In 2018, BMW launched a Roaster variation on the i8 which appeared to be a coupe with the roof off.
Yes, as a hybrid there is an environmentally-conscious feel to the car yet when you look at it there are clear supercar vibes. Those looks have not changed yet even now the car still appears stupendous.
That is in a range of colors including ‘Crystal White Pearl Effect’, ‘Protonic Blue’, ‘Sophisto Grey’, and ‘Ionic Silver’. Those titles do sound like they have come straight from the comic books but on the i8 they look very, very good.
Unfortunately, BMW decided that the evolution of the i8 has already ended. With no direct replacement forthcoming, one of the most innovative cars on the road remains just that. Hopefully, that innovation continues to last as it still seems ahead of its time.
So just how fast is the BMW i8?
Looking at the BMW i8, you may think it is a sports car and you would be largely correct. Launched in 2014, the hybrid car had already been featured in Mission: Impossible – Ghost Protocol three years earlier, and with good reason.
The BMW i8 Engine – What is the BMW i8 top speed?
The way it is powered certainly feels like fiction as the 1.5-liter, three-cylinder engine is taken from a MINI Cooper. That it can go from 0-60 MPH in four seconds should feel impressive. However, the top speed is an electronically limited one of 155 MPH.
While there are certainly supercars that can hit much higher top speeds, the combination of the electric motor and gas-powered engine offers some decent pace. The car also offers some economy as it can go as far as 25 miles on a full electric charge.
Imagine such performance in such a good-looking car that you can charge up at the office. Just make sure you get permission from the boss first.

Top 8 BMW i8 comparable cars
When it comes to comparing the BMW i8 to other cars, we have many options to choose from. The BMW i8 can be compared to several different sports cars, including the Acura NSX and Porsche 911.
The BMW i8 Roadster is an engineering marvel, and it’s a great first step into the electric vehicle world. However, as the industry continues to move forward, BMW will need to change with it to stay competitive.
Audi R8
The Audi R8 is a mid-size luxury car that is comparable to the BMW i8 in many ways. Its base model has been discontinued for the 2021 model year, but it has maintained a high level of value. Although it isn’t a hybrid, the R8 has rear torque bias that is hard to beat.
Both models offer advanced safety features. The BMW i8 features a standard City Collision Mitigation system that uses forward-mounted sensors to apply full-force brakes when it senses a collision is imminent.
The i8 has a heads-up display that projects key instrumentation readouts in front of the driver. The R8 does not have a heads-up display.
Both cars have smooth, responsive steering. The R8 is particularly smooth in handling. It rewards neutral driving, while leaning too much on the front can cause understeer.
Lamborghini Huracan
The Lamborghini Huracan is a supercharged supercar that replaces the Gallardo and is almost as powerful as the flagship model, the Aventador. Its naturally aspirated V10 engine puts out 602 hp and sprints from 0-60 in 2.8 seconds.
Its interior features premium hand-stitched leather and hexagon shapes. Whether you’re looking for speed or style, this car has it all.
The Huracan is the successor to the Gallardo and the stablemate of the R8. Both cars are great modern supercars. But there are some differences between the two. The Huracan has a sleeker design, more aerodynamics, and a faster 0-60 time. And it has new headlights.
Mercedes Benz AMG GT
The Mercedes Benz AMG GT is a high-performance hybrid car with sporty aesthetics and a solid build. Its 4.0L eight-cylinder engine delivers 469 horsepower at 6,000 rpm, and it takes 3.7 seconds to reach 60 mph. It can reach a top speed of 188 mph.
It comes with a 7-speed automatic transmission, and it features an infotainment system with audio streaming and phone integration.
The Mercedes AMG GT’s front seatbelts are pre-crash, which improves protection in the event of a crash. In contrast, the i8 lacks this feature.
In addition, the AMG GT has a lane departure warning system, which alerts the driver if the car drifts from its lane. It gently nudges the car back into its lane if it detects a lane deviation.
If you’re looking for a Mercedes Benz AMG GT that’s similar in price to the BMW i8, it would be a good idea to compare the two vehicles. They offer similar gas mileage and performance, and are similarly priced.
Mercedes Benz S-class cabriolet
The BMW i8 stands out among other Bimmers. While initial rumors indicated that the car would be based on the 7 Series, BMW instead decided to design a totally new model. This makes it a radical departure from the six-series coupe and seven-series convertible. It is also more aggressive than the Mercedes-Benz S-Class Coupe.
If you’re considering a luxury car, you’re likely to want something with top-notch technology. Both brands offer similar technology packages, but they’re distinct in terms of exterior design, cabin layout, and drivetrain options. Mercedes-Benz and BMW vehicles are known for their quality and design.
If you’re considering a BMW i8 as a possible daily driver, here’s what to look for. A BMW i8 has a relatively small trunk size. It’s smaller than a Mercedes-Benz S-Class Coupe, but it’s more spacious than an Acura NSX. The car is also quite aerodynamic.
It’s the first luxury car in its class to feature a diesel engine. The diesel engine is very strong, and is capable of producing more torque than the Mercedes-Benz S-Class Coupe. Unlike gasoline engines, it produces less cabin noise.
Porsche 718 Boxster
When comparing Porsche 718 Boxster and BMW i8, the Boxster is smaller, cheaper and lower-powered. However, it drives just as well as the 911 and uses less fuel. The boxster also has a six-cylinder engine, with a 3.4-litre flat-six making 311bhp versus the i8’s 275bhp.
The interior of the BMW i8 is functional and well-designed, though the exposed carbon-fiber tub isn’t that special. The i8 is available in coupe or convertible versions, and both have numerous interior and wheel options.
Its trunk space is smaller than its competitors, but it’s sufficient for three grocery bags. The BMW i8 is one of the most innovative cars on the road.
The BMW i8 is a sporty hybrid that redefines what it means to be a sports car. With a 1.5-litre petrol engine and a 129bhp electric motor, the i8 accelerates quickly. It has a 0-to-60-mph time of 4.2 seconds, and it feels agile and precise.
Chevrolet C8 Corvette
The new Chevrolet C8 Corvette has been so popular that a two-year wait is common at dealerships. COVID restrictions on the vehicle have caused a backlog of orders. As of November 2020, General Motors has built just 20 368 Corvette C8s.
Although the Corvette is more similar to a Porsche 911, the BMW i8 is generally compared to an Audi R8. While the Corvette lacks features such as automatic emergency braking and a manual transmission, this does not detract from its performance. On the other hand, the Corvette’s two-seat layout makes it difficult for some families.
When comparing the two cars’ performance, the Corvette has a slight edge. It offers better control and a smoother ride compared to the M4. Its engine is positioned behind the cabin, which helps it stay planted on the road. The M4 has a higher trap speed, but the Corvette has better handling and braking.
Nissan GT-R
The Nissan GT-R is a fast and powerful sports car, but there are some differences between it and the BMW i8. The Nissan uses all-wheel drive, while the BMW has a mid-mounted V10 engine. The BMW has nicer interior materials and more dramatic styling.
The BMW i8 is an excellent and efficient performance car. While it’s pricey, it is still a relative bargain. Moreover, the Nissan GT-R’s interior is dated, which makes it less attractive to the average buyer. However, it has an engine performance that defies expectations, and it costs less than other supercars.
The GT-R is less expensive to maintain than the BMW i8, with annual maintenance costs of $979. However, you’d spend more than $500 more on the i8 over its lifetime.
Lexus LC
The Lexus LC is a luxurious hybrid coupe that is among the most impressive in the class. Its exquisite exterior design and luxurious interior are examples of true craftsmanship.
The LC is also well-equipped, especially when compared to its competitors, and has a class-leading predicted reliability rating from J.D. Power. It also delivers exceptional fuel economy, while still offering a sporty driving experience.
The interior is a mix of futuristic looks and high-quality materials. The LC’s headlight design blends into the body work, with an almost vertical light cluster. The dashboard, on the other hand, is more conventionally designed, with a full-width fascia for the infotainment screen. It also features a trackpad for controlling the infotainment system.
The LC is a luxury coupe that will be offered in convertible form by 2021. It’ll feature a hybrid powertrain but lacks turbochargers and superchargers.
