Fiat 500L Living passes the Bosch ‘Diesel Challenge’ test
• Turin-Paris, nearly 800 kilometres without refuelling
• The feat was achieved by the Fiat 500L Living 1.6 MultiJet II 105 HP with Bosch Common Rail
• Less than 40 euro of diesel: the distance was covered on an average of 27 litres of fuel, corresponding to approximately 30 kilometres per litre
• The new turbo diesel ensures fun, outstanding range, low running costs and more miles before servicing.
The first edition of the ’Diesel Challenge’, created by Bosch to prove the remarkable potential of diesel engines in terms of high performance, fuel efficiency and low emissions, has just come to an end.
The feat was achieved by a fleet of Fiat 500L Living 1.6 MultiJet II 105 HP which set off on 1 October from the Mirafiori Motor Village in Turin and reached the Motor Village Fiat Café in Paris some 800 kilometres away the morning after.
The competing teams covered the distance on 27 litres of diesel fuel in average, corresponding to approximately 30 kilometres per litre. Even more remarkable was the performance of a professional driver who drove the same distance on only 20.9 litres of fuel, equal to more than 38 kilometres per litre. The same excellent results were registered by the teams who travelled back from Paris to Turin, again without stopping for fuel.
Fitted with a small fixed geometry turbocharger, a variable displacement oil pump and ’smart charge’ alternator, the 105 HP 1.6 MultiJet on Fiat 500L Living is a second generation MultiJet engine which ensures category topping economy, eco-friendliness and performance. The secret of its performance lies in the new fuel supply system with faster injectors capable of multiple injections in rapid succession. Specifically, the MultiJet II system’s servo valve technology with balanced shutter is capable of managing up to eight injections per cycle, offering greater speed, flexibility and precision in the various phases of operation.
The injector is also simpler and more reliable because its construction is less complex and it has 40% fewer components. This new type of injector paves the way for new strategies focused on optimising the increasingly advanced combustion, such as Injection Rate Shaping, which involves two consecutive injections so close together in time as to generate a continuous and modulated profile of the fuel supply into the cylinders. With this method, the combustion process is improved, with advantages in terms of quieter operation and particulate and nitrogen oxide (NOx) emissions. Today, MultiJet II engines fully comply with the Euro 5 standard and at the same time mark a decisive step toward stricter regulatory levels in the future. Naturally, the Start&Stop system is a must, while engine and transmission use low viscosity lubricant oil to minimise friction.
The extraordinary result achieved in the first edition of the Bosch ’Diesel Challenge’ emphasises the costs benefits of diesel powered cars for long-distance trips, even more so if they can accommodate many occupants providing plenty of comfort and space to everyone at the same time. Just like the Fiat 500L Living, the perfect combination of efficient use of space and unmistakable Fiat design. By adding a third row of seats, the new car becomes the most compact ’5+2 seater’ MPV in its category: in only 4.35 metres, the car has room for either seven people or five people and no less than 638 litres of load, the largest in its market sector.
Fiat 500L Living is a real ’living space’, a new concept which is based not only on technical features but above all on a different way to experience a car. Moreover, Fiat has always been the byword for innovative models bringing sophisticated, easy-to-use technological solutions and contents which provide answers to real everyday mobility needs and to the increasing social awareness towards communications, the environment and safety.
It is no coincidence that the Fiat 500L is packed with appropriately simplified ’human-friendly’ interfaces to facilitate access to the network access, navigation and infotainment systems. An example? The Fiat 500L Living fleet that took part in the ’Diesel Challenge’ was equipped with Vodafone Mobile Wi-Fi 4G Internet connection, the innovative Wi-Fi hotspot for connecting up to 10 devices and surfing the web at 4G speed up to 70 Mbps at the same time. A simple, user-friendly solution for passengers to stay connected on the road.
There is more: by using the Uconnect integrated devices fitted in their cars, the competing teams benefited from the eco:Drive Live, the application developed by Fiat to help drivers cut fuel consumption and CO2 emissions by monitoring driving style in real time and providing tips for even more eco-friendly motoring.
The Fiat 500L Living cars for the Bosch event were also equipped with Goodyear EfficientGrip tyres, the first implementing innovative FuelSaving Technology to reduce rolling resistance, responsible for fuel consumption and CO2 emissions as a consequence.
Finally, it is worth noting that Bosch and Fiat engineers have been improving diesel technology since 1990 and have succeeded in drastically decreasing emissions (nitrogen oxide emissions by 96% and participle emissions by 98%). Also, diesel engines consume 30% less fuel than traditional petrol engines allowing an increase in range of up to 40%. From the point of view of performance, maximum torque is already delivered at low rpm to secure a dynamic driving experience. For these reasons, diesel engines are appreciated worldwide, and particularly in Europe where one new registration out of two is a diesel.
