While most auto makers wrestle with the future of cars, BMW has delivered an experience from the future with the BMW i8, writes ARTHUR GOLDSTUCK, as he explores the technology of the vehicle.
It’s hard to resist the temptation, when stepping out of a BMW i8, to declare to the gaping bystanders: “Greetings! I’m from the future.”
It’s a car that makes the legendary DeLorean DMC-12 from the Back to the Future movies look positively 20th century. The “scissor doors” aren’t quite the gull-wings of the DeLorean, but that also makes it all the more sleek and practical. The latter is not, however, a word that one would typically associate with the i8.
With a price starting at around R1,8-million, the car is aimed at people for whom money is no object, and for whom the experience is everything. But it is also proof that a production vehicle coming off the assembly lines can deliver the futuristic performance and experience that is usually associated with concept cars displayed only at motor shows.
They call it a “plug-in hybrid”, which means it has a petrol engine as well as an electric motor that can be recharged from a regular wall socket. The rear-wheel drive petrol engine has a range of up to about 500km, depending on driving mode: Sport, Comfort and ECO PRO modes speak for themselves.
In pure electric mode, it has a range of up to 27km only, but the battery can be topped up while in Sports mode, thanks to “energy recuperation” which sees kinetic energy transferred from the brakes, among other sources, to the generator. The impact of advanced technology reveals itself most dramatically, however, in the vehicle’s startling fuel efficiency: 2,1L per 100km, when using a combination of electric and petrol engine. That’s less than a third of the consumption of some of the most fuel-efficient “normal” cars on the road.
BMW has installed quick-charge facilities around the country, and a built-in mapping option directs the driver to the nearest one when needed. It has an agreement with Nissan to standardise charging technology and collaborate in installing interoperable charge points for the Nissan Leaf, BMW i3 and the i8.
Let’s climb aboard. But wait! First, download the app onto your smartphone or tablet.
The BMW i Remote app is available for Android and iOS devices. From the app, the vehicle can be locked or unlocked remotely – via the Internet, rather than infrared, so one can do it from the other side of the world. The air conditioner can also be activated remotely before you reach it, a particularly welcome feature when the car has been standing in the hot sun for a while. Control of doors, windows, trunk, and lighting is all accessible via the app.
The car doors are heavy, but lift and close easily. The only discomfort is having to lower oneself into the car rear-first. It’s not difficult to get used to, but not especially elegant for anyone wearing a dress, for example. And certainly not for those who have back or movement trouble.
And then the magic begins. It’s not so much the luxurious leather interior or the chrome finishes or even the sheer comfort of the reclining seats with their multiple controls. The blue-lit lines and futuristic sound-effects when the car is activated – “start” is such an inadequate word to describe it – combine with the information-rich dashboard and 8.8-inch control display to suggest words like “spaceship” and “future” and “desire”.
The one negative is the navigational option on the control display. Not only is it fairly standard, but is even clunky. Destination choice uses a rotary system for choosing an address letter-by-letter. The voice recognition system should get round the painfulness of the system, but it results in the typical kind of voice-wrestling one associates with systems designed for American accents.
That said, BMW has reinvented even this option. Prior to a trip, one can visit the company’s Connected Drive portal and use its mapping system to find an address, and then send the address to the car. This means one simply opens the message from the menu on the control display and approves the destination.
And this is where the future truly arrives. The vehicle uses a subtle heads-up display system to beam both vehicle speed and current speed limit onto the windscreen, just below where one’s eyes would be focused on the road. If navigation has been activated, a streamlined version of map guidance appears on the windscreen, alongside the speed. In direct contrast to the chunkiness of the control display navigation, the image provides dazzling clarity: distance to turn, action required and an uncluttered diagram of any intersection where the turn has to be made. Think Minority Report without the gesture control.
The heads-up display symbolizes the advanced technology of the car. One might call it a smartphone on wheels, but few smartphones are this smart. While your phone may sport Siri or Google Now or Cortana voice assistance, the i8 provides a real-life Concierge option: activate it, and a human being comes online to answer questions about destinations, attractions or facilities. Typically, the mapping coordinates are then emailed directly to the car, the option is selected, and map guidance begins.
In an emergency, a single Help button on the dashboard instantly dials an emergency call centre. If the car is in an accident and the airbags deploy, a signal is sent to the call centre, which calls back to see if help is needed. If there is no response, an emergency vehicle is immediately despatched.
The driving experience is magnificent. BMW uses the slogan “Magnetism not required to feel the force of attraction”, which sound meaningless until one takes a curve at normal driving speed. It feels as if the vehicle has attached itself to the road surface with Velcro, but without slowing down.
The i8 is constructed from carbon fibre, plastic and aluminium, meaning it is ultra-lightweight and therefore highly responsive to controls. The material doesn’t make it unsafe either: carbon fibre surrounds the passenger area, creating what is called a “Life module” which, along with airbags, gives passengers maximum protection.
The weight also contributes to the vehicle’s fuel efficiency, and allows for a maximum speed – in petrol mode – of 250km/h. Acceleration is astounding: 0-100km/h in 4.4 seconds.
The aerodynamics of the vehicle are also key to its performance. It resembles nothing less than a Batmobile, with its sleek lines, low structure – what BMW refers to as a “flat silhouette” – and handleless doors. That low centre of gravity also provides the Velcro experience on curves.
Ultimately, the defining feature of the vehicle is the experience of being transported into the future. This is what one imagines the vehicles of tomorrow could deliver to all drivers.
It is no wonder that the i8 attracts stares of delight, shock and even horror wherever it goes and whenever it stops. It is little wonder that people almost believe you for a moment when you lift open the door, step out and declare: “Greetings! I’m from the future.”
Jaguar Land Rover and BMW team up for electric tech
The collaboration seeks to advance consumer adoption of electric vehicle technology.
Jaguar Land Rover and BMW Group are joining forces to develop next generation Electric Drive Units (EDUs) in a move that will support the advancement of electrification technologies, a central part of the automotive industry’s transition to an ACES (Autonomous, Connected, Electric, Shared) future.
The strategic collaboration will build on the considerable knowledge and expertise in electrification at both companies. Jaguar Land Rover has demonstrated its leading technical capability in bringing the world’s first premium battery electric SUV to market – the 2019 World Car of the Year, the Jaguar I-PACE, as well as plug-in hybrid models; and BMW Group bringing vast experience of developing and producing several generations of electric drive units in-house since it launched the BMW i3 in 2013.
Nick Rogers, Jaguar Land Rover Engineering Director said: “The transition to ACES represents the greatest technological shift in the automotive industry in a generation. The pace of change and consumer interest in electrified vehicles is gathering real momentum and it’s essential we work across industry to advance the technologies required to deliver this exciting future.
“We’ve proven we can build world beating electric cars but now we need to scale the technology to support the next generation of Jaguar and Land Rover products. It was clear from discussions with BMW Group that both companies’ requirements for next generation EDUs to support this transition have significant overlap making for a mutually beneficial collaboration.”
The agreement will enable both companies to take advantage of efficiencies arising from shared research and development and production planning as well as economies of scale from joint procurement across the supply chain.
A team of Jaguar Land Rover and BMW Group experts will engineer the EDUs with both partners developing the systems to deliver the specific characteristics required for their respective range of products.
The EDUs will be manufactured by each partner in their own production facilities. For Jaguar Land Rover this will be at its Wolverhampton-based Engine Manufacturing Centre (EMC), which was confirmed as the home for the company’s global EDU production in January of this year. The plant, which employs 1600 people, will be the centre of propulsion system manufacturing offering full flexibility between clean Ingenium petrol and diesel engines and electric units. The EMC will be complemented by the recently announced Battery Assembly Centre at Hams Hall, near Birmingham, in supplying electrified powertrain systems to Jaguar Land Rover’s global vehicle plants.
Sensory steering wheel lets drivers feel the heat
Jaguar Land Rover researches rapid heating and cooling of the steering wheel for use with turn-by-turn navigation.
A steering wheel developed by Jaguar Land Rover could help keep drivers’ eyes on the road – by using heat to tell drivers when to turn left or right.
The research, in partnership with Glasgow University, has created a ‘sensory steering wheel’, parts of which can be quickly heated and cooled to inform drivers where to turn, when to change lane or to warn of an approaching junction. This could be particularly useful when visibility is reduced through poor weather or the layout of the road.
The technology has also been applied to the gear-shift paddles to indicate when hand over from the driver to autonomous control in future self-driving vehicles is complete.
Driver distraction is a major contributor to road accidents around the world and accounts for 10 per cent of all fatal crashes in the USA alone*. Jaguar Land Rover’s research suggests thermal cues could be a way to keep drivers fully focused on the road.
The cues work on both sides of the steering wheel, indicating the direction to turn by rapidly warming or cooling one side by a difference of up to 6°C. For comfort a driver could adjust the range of temperature change.
Studies have shown** temperature-based instructions could also be used for non-urgent notifications, where vibrations could be deemed unnecessarily attention grabbing, for example as a warning when fuel is running low, or for upcoming events, such as points of interest. Thermal cues can also be used where audio feedback would be deemed too disruptive to cabin conversations or media playback.
Alexandros Mouzakitis, Jaguar Land Rover Electrical Research Senior Manager, said:“Safety is a number one priority for Jaguar Land Rover and we are committed to continuously improving our vehicles with the latest technological developments as well as preparing the business for a self-driving future.
“The ‘sensory steering wheel’ is all part of this vision, with thermal cues able to reduce the amount of time drivers have to take their eyes off the road. Research has shown people readily understand the heating and cooling dynamics to denote directions and the subtlety of temperature change can be perfect for certain feedback that doesn’t require a more intrusive audio or vibration-based cue.”
The Jaguar Land Rover-funded research is part of a PhD study undertaken by Patrizia Di Campli San Vito at Glasgow University as part of its Glasgow Interactive Systems Research Section (GIST).
Jaguar and Land Rover models already boast a wide range of sophisticated Advanced Driver Assistance Systems (ADAS) designed to improve driver and vehicle safety, including the new generation Head-Up Display in the Range Rover Velar. The Velar also features capacitive steering wheel controls for common functions that combine with the Interactive Driver Display to help reduce driver distraction.
