The BMW Group has a reputation for building large engine automobiles, but the eco-friendly hybrid i8 has given a whole new meaning to the phrase “sheer driving joy” for the company. By fusing the TwinPower Turbo technology created for their infamous M models with the environmentally friendly eDrive technology, BMW developed the plug-in hybrid, all-wheel-drive idea.
In the BMW i8, a two-stage automatic transmission transfers power from the electric powertrain to the front wheels. On the other side, a gasoline engine connected to a 6-Speed automatic transmission drives the vehicle’s rear wheels. This is the ideal fusion of strength and efficiency.

EV Performance, Power, and Motor
The i8 from BMW has just one available powerplant. A 1.5-liter, three-cylinder turbocharged gas engine is coupled with an 11.6-kWh battery and two electric motors in this vehicle. With their combined 369 horsepower, the trio of engines can move all four wheels. But it’s not the quickest supercar around: In 4.1 seconds, the 2019 i8 roadster we tested could accelerate from 0 to 60 mph. The same mild steering we’ve questioned in many recent BMWs is present in the i8. More feedback is preferred, especially in a vehicle designed with sporting purposes. Surprisingly, the ride is smooth, and road imperfections are felt but never sharply.
Engineering and Design
Let’s start with the design, which hasn’t altered but probably didn’t need to because the i8 is still startlingly stunning when it’s stopped and even more impressive when the dihedral doors are opened upward.
Although the i8 blends this interior design with the typical levels of BMW functionality, the cabin also offers a sense of the future. It even includes two tiny rear seats for kids since it is a 2+2. In addition, there is a luggage compartment located behind the engine, however it is somewhat small due to the storage of two charging wires.
The outside is stunning, and the interior is also really remarkable. However, the really intriguing technology is hidden behind the skin.
A plug-in hybrid is the i8. This implies that it has a gasoline engine that is linked to a six-speed Steptronic transmission and an electric motor that is driven by a lithium-ion battery and has a two-speed automatic gearbox. The lithium-ion battery’s energy capacity has increased from 20Ah to 34Ah in the most recent model of the i8, and the electric motor’s maximum power has improved by 12hp to 143hp.
You could assume that the ‘traditional portion’ of the i8’s powertrain is similar to a BMW 6-cylinder, 3-liter gasoline engine based on the vehicle’s appearance. But instead, a 1.5-liter, 3-cylinder petrol engine that came from a MINI is sat behind the passengers. a supercar powered by a 1.5-liter, 3-cylinder gasoline engine? Really? But keep in mind that the 231 horsepower of the gasoline engine is complemented by a 143 horsepower electric motor, giving the system a total power output of 374 horsepower. Now that you mention it, it makes more sense. It’s also important to note that the gasoline engine now has a particle filter.
The i8’s ability to transfer its power to the road is another concern. The front wheels receive power from the electric motor while the rear wheels receive it from the mid-mounted gasoline engine. All-wheel drive is created when these two propulsion methods are combined.
The i8 features two powertrains but only 1,535 kg of total weight thanks to its carbon fiber reinforced plastic (CFRP) passenger cell.
It is what?
The i8 still feels like it arrived on earth via a spacetime rift four years after launch. But now, this is what we humans refer to as a facelift. The face hasn’t really changed, though. The beautiful Roadster version is the main story. Many of the same under-the-skin adjustments are also made to the Coupe, helping to improve both its handling and effectiveness.
The i8 seems quite radical. Aesthetically, crowd-pleasing flamboyance is skillfully incorporated with minimal-drag shape-work for efficiency.
As unconventional and daring as the aesthetics are the drivetrain and the structure. A large 143 horsepower electric motor powers the front wheels, while a compact, mid-mounted 231 bhp gasoline engine propels the vehicle’s rear wheels using a six-speed automatic transmission.
That makes three different types of propulsion possible. When in sports mode, the AWD sports car driving performance is comparable to that of the M4 from BMW. The hybrid mode is quite effective and serene. Alternatively, it can use the plug-in battery reserve to travel up to 75 mph only on electricity.
Whether the energy is generated by gasoline or electricity, the car may fine-tune its driving style to consume the least amount.
Low drag and little rolling resistance are both components of that; just have a look at their tyres. Another is its lightness. The 1,535kg Coupe weighs. Even the Roadster weighs less than 1,600kg—less than a 911 with 4WD, an automatic transmission, and an electric top. How did they manage that? utilizing a carbon fiber tub with lightweight external panels and aluminum subframes.
However, it was such a moonshot when it was first developed that its engineers prudently took some precautions. With the advantage of experience, they have also boosted the main traction motor and battery, which now hold 70% more energy than previously. Electric range, hybrid performance, and fuel efficiency all benefit. Now, it should have a practical electric range of 20 to 25 miles, and the Coupe’s stated CO2 emissions are as low as 42 g/km.
Additionally, by employing revised front damper calibration and a stronger rear anti-roll bar, they have reduced the original’s front understeer. These modifications are made to the Roadster, and the coupe ups the sportiness a level.
The Roadster is more than just a seasonal spyder. The three-layer electrified cloth roof is soundproof and fully weatherproof. Thus, it gives this incredible car a new dimension. You feel enchantingly close to the streetscape as you silently cruise through a town in electric mode with the roof down. However, you still have the coupe’s ability to be a true all-weather ground coverer with the roof up and in 4WD sports mode.
What You Need to Know About the BMW i8 Coupe, an Electric Vehicle
The BMW i8 Coupe is a unique vehicle with futuristic styling, a hybrid motor, and a ton of amenities you won’t find in any other car in its class. That’s because it might be the purest hybrid sports car in the entire world. The i8 wants to dominate the sports car market in the future without sacrificing the design aesthetics and performance of its gasoline-powered rivals.
For almost two decades, the terms “hybrid” and “sports vehicle” were virtually synonymous. Although hybrids place a strong emphasis on improved fuel economy, performance was frequently sacrificed. The i8, however, performs both. A massive 369 horsepower and 420 pound-feet of torque are produced by the vehicle’s 1.5-liter twin-turbo three-cylinder engine in combination with an electric motor and 11.6-kWh lithium-ion battery.
The result is an outstanding 0-60 time of 4.0 seconds and a top speed of 155 mph for the i8.
The BMW i8 also has a plug-in hybrid powertrain, which enables you to charge the car via an outlet and only use electricity while driving. The i8 has a range of up to 18 miles when fully charged, and when it switches into hybrid/gasoline mode, it produces the equivalent of 29 mpg.
The i8 has a ton of high-tech stuff within. Highlights include head-up display, park distance control, navigation, multimedia system, and a sunroof that extends from the windshield to the rear window.
The 2018 BMW i8 Coupe is an exhilarating, daring glimpse into the future of not only BMW, but sports automobiles in general. Its ambition is undeniable. Take part in the uprising.
Detailing the BMW i8’s hybrid powertrain in a video
The BMW i8 continues to fascinate us with its style and technology despite being over three years old. Everywhere it goes, the hybrid sports car instantly draws attention, and its distinctive appearance has created a cult among aficionados. The team at Feature Focus has created a thorough film to showcase its high-tech skills.
The i8 has an internal combustion engine and an electric motor that work together to propel you forward. An electric engine with 131 PS and 184 lb-ft (250 Nm) of torque is mounted on the front axle, and its only purpose is to drive the front wheels and eventually transport you around town without emitting any pollutants.
The more entertaining portion of the game is powered by a 1.5-liter 3-cylinder turbocharged engine on the back axle, which has 231 PS and 236 lb-ft (320 Nm) of torque. It exclusively drives the rear wheels and is coupled to an automated transmission with six speeds. The 6-speed gearbox of the internal combustion engine and the 2-speed gearbox of the electric motor were combined by engineers to ensure that the two could operate together and provide the car with up to 362 PS and 420 lb-ft (570 Nm) of torque when necessary.
Additionally, by doing this, they were able to produce a vehicle that can operate as a front-wheel drive, all-wheel drive, and – for a brief period of time – a rear-wheel drive vehicle. This is feasible because the rear engine is shut off while the vehicle is in Eco Pro mode, relying exclusively on the front electric motor to move the vehicle through town.
The i8 is frequently seen as the auto industry’s future for the same reason. The i8 demonstrated that you don’t need a powerful engine to have fun thanks to its lightweight design, which was largely achieved through the use of CFRP.
How is a BMW i8 fueled?
The BMW i8 Hybrid is an amazing car. Few modern cars can match its exotic styling, and even fewer can claim to offer the same level of comfort for the driver and passengers. The BMW i8 leads the pack in several of these categories, but it is not without its flaws. The sticky gasoline door that can leave you trapped at the pump is one particular oddity that aggravates both vehicle owners and renters.
In an effort to create “The Ultimate Driving Machine,” BMW compressed the i8 hybrid’s whole fuel system. “Preparing To Refuel” will be shown on the dashboard when you press the fuel door release button on the driver’s door. Rarely, the door won’t open and the notification will remain on the dash. Follow these easy methods to swiftly open the fuel door if this ever occurs to you.
- On the driver’s side door, push the button to open the fuel door.
- Look at the dashboard to see the message “Preparing To Refuel.” There will probably be a percentage with this message.
- If this process doesn’t finish on its own after 30 seconds, wait some more.
- The car’s trunk should be opened. There is a trunk release on the driver’s side door as well.
- the vehicle’s passengers side access panel should be removed.
- Release the green tab.
- To release the gasoline tank door, press it.
The BMW i8 is a hybrid, right?
The BMW i8 is a cutting-edge sports automobile that uses hybrid technology throughout its entire drivetrain. Let’s look at some of the specifications: Powertrain: eDrive Electric Motor and 1.5L BMW TwinPower Turbo 3-cylinder engine. Engine power is 228 horsepower and 236 lb-ft.
A BMW i8 has how many gears?
The three-cylinder TwinPower 1.5-litre engine in the i8 is effectively a substantially modified version of the one found in the standard Mini Cooper, despite the fact that BMW won’t thank us for admitting it.
Because it produces 228 horsepower and 236 lb ft of torque, we think it has been reworked. This is then coupled with a front-axle electric motor to create 129 horsepower and 184 pound-feet of torque.
As if the powertrain weren’t confusing enough, the starter motor produces 11 horsepower of hybrid drivetrain and also fills in for torque when the petrol engine’s turbo is still spinning up.
A transmission that was equally as clever was required given the complex drivetrain. In essence, a six-speed automatic box transmits power from the gasoline engine to the back wheels while a two-stage automatic box at the front controls the electric motor. The six-speed transmission can be operated by the driver either manually or by using the shift paddles on the steering wheel.
The gearbox performs as expected in Eco mode, shifting up precisely when it is needed to maximize efficiency. However, if you go to Sport, it will hold gears much longer. Although not as quick as a double-clutch gearbox, shifts happen quickly enough.
