Interview: hybrid and electric technologies are changing the way cars are made after decades of stagnation, in accordance to BMW’s Benoit Jacob, speaking exclusively to Dezeen about the i8 sports auto .
Nominated for the 2015 Designs of the Yr award, the BMW i8 – a plug-in hybrid powered by an electrical motor in conjunction with a petrol engine – was conceived as a substantial-efficiency sports activities vehicle that emits fewer emissions than a tiny city runaround.
Jacob, the designer of BMW’s i8, explained to Dezeen that following almost a century of growth autos have evolved into an nearly “perfect” kind, which has produced it a lot more hard for manufacturers to push the boundaries and develop distinct models.

“Vehicles have created enormous methods in terms of good quality, appearance, safety and overall performance,” he mentioned. “It really is a excellent model, which is really challenging to formally evolve.”
But recent technological advances and new lightweight resources have presented a different set of style issues and aesthetic possibilities, which Jacob and the BMW i team explored in the creation of the i8.

“My personal conviction is that there is no very good design and style if there are no excellent constraints,” explained Jacob. “You need to have some guidelines.”
“What is intriguing in the improvement of a hybrid car is that the constraints have been somewhat changed from those of a traditional car,” he explained. “The way you develop a hybrid is various.”
“It dramatically alters the proportions, which right impacts on the layout. We saw that as an chance to move auto layout forward.”
The consequence is a minimal-sitting vehicle incorporating clean, minimalist lines, with a framework of overlapping and interlocking surfaces – emphasised by the car’s contrasting colour scheme – and a V-shaped “black belt” that runs from the bonnet, extending over the roof into the vehicle’s rear segment.
The outer skin is produced out of thermoplastic polymers, a materials that is half the bodyweight of sheet steel, and the doors open forwards and upwards.
“The i8 tries to express state-of-the-artwork aerodynamics formally,” mentioned Jacob. “We have tried to make what it can accomplish visible and understandable.”
“The front has to obviously signal that this comes from the home of BMW,” he additional. “Of program, we were given a bit of freedom to reinterpret these aspects, so for the i8 we extra a blue hue to the kidney grille to signal its electrical capability.”
Creating visual cues to the i8’s efficiency was crucial to Jacob, who knew he had to provide a particular automobile in purchase to win above a marketplace sceptical of hybrid automobiles.
“It was clear from the beginning that the i8 would have to stand out from the crowd as a statement,” mentioned Jacob. “When it comes to electric mobility, nobody is prepared to give up on the great factors we presently have. Nobody desires to say the get together is more than.”
Read through on for an edited transcript of our interview with Benoit Jacob:
Ross Bryant: Can you introduce your self and your part at BMW?
Benoit Jacob: I am Benoit Jacob and I’m responsible for BMW i design as nicely as the innovative design and style for BMW Group.
Ross Bryant: In your personal phrases, what is the i8?
Benoit Jacob: The i8 is like the sports activities auto reinvented, the clever sports activities vehicle or intelligent sports activities car in the sense that it truly is a car that achieves quite a great deal with quite minor. What I suggest by that is that it has to deliver a lot of emotion and elegance with good functionality, but with fewer emissions and significantly less resources. This describes the i8 fairly well – to be what could be the sports activities car of the long term.
When it comes to electric mobility, no one is ready to give up on the very good factors we already have. Nobody desires to fundamentally say the party is over. So rather, we asked how we could offer a substantial level of emotion and excitement by means of a sustainable layout.
The i8 could be the sports activities auto of the potential
Ross Bryant: How have been you in a position to inject that emotion into a hybrid vehicle?
Benoit Jacob: 1st, the notion itself. When we ground [the sports activities automobile] to the BMW i brand it was variety of untypical to opt for. We could’ve stated “let us leave it up to a city vehicle or a family members car” but we desired to declare a extremely strong BMW statement by saying, “no, we’ll still deliver a automobile for sheer driving pleasure and reinvent it in a way or define it in a new method, offering sheer driving pleasure a new interpretation”.
We mentioned that a sports auto would in fact be exciting to pour all our concepts and technical innovations in to, because of course, what describes an i8 is the engineering – such as the electric drivetrain – but we also speak about the light-weight technologies this kind of as carbon fibre and highly effective aerodynamics.
Ross Bryant: Were the aesthetics of the car totally driven by aerodynamics?
Benoit Jacob: Yeah, but nevertheless also in dialogue with the stylist or the designer. Usually when it comes to aerodynamics we know how to produce a really aerodynamic form for a automobile or an object. A teardrop or a water drop is the optimum form we need for an aerodynamic car. The only factor is: is this desirable ample, and is this sexy adequate? So we came up with options that we could produce and put in the wind tunnel. In a way, the i8 tries to express state-of-the-artwork aerodynamics formally.
Ross Bryant: So type closely follows function?
Benoit Jacob: Precisely, because there are even some surfaces we did not have to model ourselves. They have been automatically given by nature.
There is no great style if there are no great constraints
Ross Bryant: How is auto style altering in response to hybrid and electric systems? What are the aesthetic opportunities for a automobile designer?
Benoit Jacob: My personalized conviction is that there is no very good design if there are no good constraints – you need to have some rules so the style is not constantly commencing from a white piece of paper.
What is interesting in the growth of a hybrid vehicle is that the constraints have been slightly altered to these of a typical vehicle. The way you construct a hybrid is diverse. The engineering, such as the electric drivetrain, has a huge effect on the architecture of the vehicle. It drastically alters the proportions, which has a direct influence on the design and style.
We saw that as an chance to move automobile design forward, or modify a tiny bit since nowadays cars in a sense are a extremely main solution, which are really really excellent. Right after nearly 100 years of development it appears that it is really difficult now to make them evolve.
The automobiles have manufactured massive actions in terms of quality, physical appearance, safety and overall performance even though still providing that at an cost-effective price tag given the quantity of engineering and complexity concerned. So it truly is a extremely best model, which is extremely hard to formally evolve. And we see that now with the second generation of automobiles that have a tendency to repeat a tiny bit of the preceding generation with modest formal modifications, but the distinctions are not so significant as they could have been twenty or 30 many years in the past.
Ross Bryant: So how did you marry design and style constraints with a new form language for the i8? What possibilities had been there for the design and style?
Benoit Jacob: The possibilities, I would say, are the style freedoms gained through employing new components. For example, we use thermoplastics to develop layers to boost aerodynamics. We also use it for the fenders on the back – it is achievable to add them since of the carbon construction and in a way this offers us a design and style freedom that we did not genuinely have just before, simply because we can create more complex shapes with a lot more legacies.
We also use thermoplastic in some spots to be even a lot more exact in the edges, so from a formal viewpoint we are freer as designers. Of course we nonetheless have to recognize the constraints – you have to find out them and put them alongside the process – but at the very finish if there is a strong dialogue amongst engineering and design there’s a payback that final results in a really different interpretation when it comes to layout.
Hybrid technology has a huge influence on the architecture of the vehicle
Ross Bryant: There are certainly constraints placed on designers by nature such as wind resistance. But is brand identity also a constraint? How did you create a auto that was nonetheless recognisably a BMW?
Benoit Jacob: On one particular side this [BMW i] is a new brand and it truly is a new technologies. We know consumers expected a bit of differentiation. It was clear from the starting that the i8 would have stood out from the crowd as a statement. On the other hand, we had to recognise BMW as the mother brand. So the way we did it was really simple. We explained Okay, the front has to obviously signal that this comes from the residence of BMW.
So we repeated the icons such as the kidney grille. Of program, we have been offered a bit of freedom to reinterpret these components, so for the i8 we additional a blue hue to the kidney grille to signal its electrical capability.
Then we began to also bring some aspects particular to the BMW i brand this kind of as this very sturdy contrast between the body factors – the entire body colour – and black belt, which run across the prime of the vehicle.
What we are trying to do with the type language is to be a bit cleaner on some surfacing but with much more intensive detailing. If you seem on the rear for instance, it suggests aerodynamics. The rear diffuser with the very powerful contrast between the black panel and the floating layer – the place you put the licence plate – suggests the lightness of the auto as effectively as the aerodynamic idea. So in a nutshell we have essentially attempted to make what the i8 can obtain visible and understandable.
