And rest assured, Jaguar has a plan to transition its methods of propulsion to deliver hugely lower emissions – with the eventual goal of eradicating them – just as smoothly as its current engine line-up accelerates. The challenge, and opportunity, is to do so while ensuring that every emerging model is true to Jaguar’s individuality in a carbon-conscious world. Powertrain (engine and transmission) development remains the salient but by no means only focus for energy saving, as Jaguar’s research and development director, Dr Wolfgang Epple explains: “Environmental innovation is at the heart of our business strategy. We know that the 72 j THE DESIGN ISSUE

TECHNOLOGY creation of vehicles which consume less fuel, emit less CO 2 and are more sustainable, cannot be achieved by the introduction of hybrid and battery powertrains alone.” Innovative complementary technologies are a must to achieve essential integrated solutions, he says. These include the reduction of energy-wasting friction in engines, cutting on-board energy requirements from things like heating and ventilation systems, improving aerodynamics and using lighter-weight materials like aluminium. Jaguar has a strong history taking this lightweight approach, from the initial XK120s launched as far back as 1948 to the 2002 all-aluminium-bodied XJ which helped it to save 200kg over its previous model. By making cars lighter, less fuel is needed to power the car forward and fewer emissions result. Jaguar has continued this approach in successive models since then, and is without question, a world leader in the production of aluminium-intensive cars. More recently, Jaguar has stepped up its efforts again. “In 2008 we began a multi-billion pound research programme,” says Dr Epple, “to directly address the challenge of significantly reducing the carbon footprint of our high-performance premium vehicles while maintaining the attributes of luxury, performance, refinement and comfort that our customers expect. While hybrid and pure electric research programmes are in place, development of internal combustion technology continues apace. The latest four-cylinder Ingenium petrol and diesel engines from Jaguar’s all-new Wolverhampton manufacturing plant, power the XE and XF. They demonstrate how to meld the need for smaller power units and deliver excellent power outputs with low CO 2 emissions and fuel consumption (indeed the 163hp XE diesel’s 99g/km put it first in its segment at launch). Advanced transmissions are an essential complement to this process, carefully matching power output to achieve greater efficiency while ensuring that all Jaguars provide driver satisfaction. Jaguar is also harvesting energysaving solutions. “We are researching a range of technologies including how we could mix carbon fibre with flax,” reveals Dr Epple. Flax, as a food and fibre crop, provides an alternative material that is one element within the “ THE CHALLENGE AND OPPORTUNITY IS TO ENSURE THAT EVERY EMERGING MODEL IS TRUE TO JAGUAR’S INDIVIDUALITY IN A CARBON- CONSCIOUS WORLD ” multi-partner CARBIO project of which Jaguar is a member. The project is working on all sorts of structures for use inside cars with reduced weight, cost, environmental impact and also less noise, vibration and harshness (also known as NVH). All of which means less sound deadening material will be required and makes extra weight savings possible. Hybrid vehicles – using a combination of internal combustion engines and electric motors – are another solution to reducing emissions and fuel consumption and Jaguar is now looking far into the 2020s at new powertrains that could deliver the essential combination of performance, luxury, packaging and handling in keeping with the brand’s values, while delivering a further step change in fuel consumption and emissions reduction. One of these is the radial flux machine, part of another collaborative research project that receives funding from the British Government-backed Innovate UK programme. Mike Richardson, Jaguar Land Rover’s chief technical specialist, says: “Slim, light and extremely powerful, they produce up to twice the power of today’s production technology and would allow us to produce virtually any hybrid or battery vehicle configuration.” Jaguar’s 2010 C-X75 concept – more recently turned into the baddie-mobile for 2015’s James Bond Spectre film – has an electric motor for each wheel and tiny Bladon gas turbine engines to provide range extension up to a remarkable 560 miles. That concept already indicates how the company could combine sustainable technology with high performance driving fun, emitting just 28g/km of CO 2 but also dispatching 0-62mph in 3.4 seconds. Forward-wind to 2016 and Jaguar’s commitment to a return to racing later this year via the fully-electric Formula E series (see our separate feature on p16), and it becomes increasingly clear that the brand is serious about this technology and electrically-propelled production cars to follow. As Nick Rogers, group engineering director for Jaguar Land Rover, concludes: “Formula E will give us a unique opportunity to further our development of electrification technologies and test our advanced technologies under extreme performance conditions.” In other words, Jaguar’s future powertrain path is well under way and promises to be as exciting as its past.

THE JAGUAR #03

 

THE JAGUAR magazine celebrates the art of performance with exclusive features that inspire sensory excitement, from dynamic driving to seductive design and cutting-edge technology.

The latest issue of The Jaguar magazine introduces our new ‘cub’, the E-PACE compact practical sports car, which is already turning heads on the street. As we commit to electrifying every new Jaguar from 2020, we explore how pushing boundaries on track helps develop our sports cars, from writing motorsport history at Le Mans, to taking on the Nürburgring with the extreme XE SV Project 8 and being at the very cutting edge with the FIA Formula E Championship.
