The values of fuel consumptions and CO2 emissions shown were determined according to the European Regulation (EC) 715/2007 in the version applicable at the time of type approval. The fuel consumption and CO2 emission ﬁgures refer to the WLTP cycle.
In order to be placed on the market, passenger cars carry out a series of tests to verify their compliance with regulations.
The tests to assess fuel consumption, CO2 and pollutant emissions are carried out in the laboratory and are based on speciﬁc driving cycles. In this way, the tests are reproducible and the results comparable. This is important because only a laboratory test, which follows a standardized and repeatable procedure, allows consumers to compare different car models. On 1 September 2017, the new Worldwide harmonised Light-duty vehicle Test Procedure (WLTP) came into force in Europe and will gradually replace the New European Driving Cycle (NEDC) protocol. NEDC (New European Driving Cycle): it has been the European driving cycle used so far for the measurement of fuel consumption and emissions from passenger cars and light commercial vehicles. The ﬁrst European driving cycle came into force in 1970 and referred to an urban route. In 1992 it was also considered to have an extra-urban phase and since 1997 it has been used for measuring consumption and CO2 emissions. However, the composition of this cycle is no longer consistent with current driving styles and distances travelled on different types of roads. The average speed of the NEDC is only 34 km/h, accelerations are low and the maximum speed is just 120 km/h. WLTP procedure: WLTP uses new Worldwide harmonised Light-duty vehicle Test Cycles (WLTC) to measure fuel consumption, CO2 and pollutant emissions from passenger cars and light commercial vehicles. The new protocol aims to provide customers with more realistic data, better reﬂecting the daily use of the vehicle. The new WLTP procedure is characterized by a more dynamic driving proﬁle with more signiﬁcant acceleration. The maximum speed increases from 120 to 131.3 km/ h, the average speed is 46.5 km/h and the total cycle time is 30 minutes, 10 minutes more than the previous NEDC. The distance travelled doubles from 11 to 23.25 kilometers. The WLTP test consists of four parts depending on the maximum speed: Low (up to 56.5 km/h), Medium (up to 76.6 km/h), High (up to 97.4 km/h), Extra-high (up to 131.3 km/h). These parts of the cycle simulate urban and suburban driving and driving on extra-urban roads and motorways. The procedure also takes into account all vehicle’s optional contents that affect aerodynamics, rolling resistance and vehicle mass, resulting in a CO2 value that reﬂects the characteristics of the single vehicle.
The WLTP procedure will gradually replace the NEDC procedure. The WLTP applies to new passenger car models from 1 September 2017, to all passenger cars registered from 1 September 2018 and is mandatory for all EU Member States. Until the end of 2020, both fuel consumption and CO2 emission values in WLTP and NEDC will be present in the vehicle documents. Indeed, NEDC values will be used to assess the average CO2 emissions of cars registered in the EU throughout 2020. In addition, some countries may continue to use the NEDC data for ﬁscal purposes. From 2021 onwards, WLTP data will be the only consumption/ CO2 emissions values for all cars. Used vehicles will not be affected by this step and will maintain their certiﬁed NEDC values.
ROAD CONSUMPTION AND EMISSIONS OF PASSENGER CARS
The new WLTP test procedure is more representative of current driving conditions than the NEDC procedure, but it cannot take into account all possible cases including the effect of the driving style that is speciﬁc to each individual driver.
Therefore, there will still be a difference between emissions and consumption measured in the laboratory and those resulting from the use of the vehicle in the real world, and the extent of this difference will depend on factors such as driving behavior, the use of on-board systems (e. g. air conditioning), trafﬁc and weather conditions that are characteristic of each geographical area and each driver. For this reason, only a standardized laboratory test allows to obtain values with which it is possible to compare vehicles and different models in a fair way.
WHAT CHANGES FOR CUSTOMERS
The new WLTP procedure will provide a more realistic criterion for comparing the fuel consumption and CO2 emission values of different vehicle models as it has been designed to better reﬂect real driving behavior and take into account the speciﬁc technical characteristics of the individual model and version, including optional equipment.
The Ferrari Portofino M’s 8-speed dual-clutch gearbox is completely new and replaces the Portofino’s 7-speed version. It is based on a dual-clutch oil bath architecture with a 20% smaller clutch module and 35% higher torque delivery. The transmission software strategy has also been evolved with a more powerful ECU. The introduction of the eighth gear and the improvement in transmission efficiency have resulted in a reduction in fuel consumption in urban and motorway contexts in addition to noticeably improving performance.
By tradition, every single Ferrari has its own particular soundtrack that makes it unique. The Ferrari Portofino M is no exception. To achieve this, the geometry of the entire exhaust line was completely redesigned. The two rear silencers have been eliminated and the by-pass valves are now oval in shape. The result is that the new Prancing Horse GT 2+ spider’s engine has an even more exhilarating soundtrack with even higher sound quality.
The aim of the five-position Manettino, a first on a Prancing Horse GT spider, is to make the Ferrari Portofino M’s handling and grip even more accessible by extending the setting ranges still further with the addition of the Race position. Supported by the introduction of the Ferrari Dynamic Enhancer, that position focuses on maximising driving pleasure.
The redesigned front bumpers incorporate imposing new air intakes, which lend a decisive look to the front of the car. They also feature a new air vent at wheelarch height, a subtle feature that cleverly reduces the car’s overall drag. Part of the air flow coming off the front radiating masses is directed towards the new vents and then accelerated up as it exits, boosting its extraction power. The grille features new aluminium slats with contrasting faceted tips that highlight this noble material.
At the rear of the Ferrari Portofino M the new exhaust system has allowed the removal of the silencer assembly, making its tail more compact. The result is that the rear bumpers are now more streamlined and sculptural. Consequently, their styling is more in harmony with the front bumpers, creating a much more coherent overall aesthetic. The rear diffuser has been completely redesigned and is now separate to the bumpers. This means it can be specified in carbon-fibre, which further underscores the car’s sporty character.
Specific diamond-finish wheel rims were designed for the Ferrari Portofino M. Their styling references that of the car’s flanks, a perfect marriage of elegance and sportiness. The unusually sculptural design of the spokes and their chiaroscuro look visually lightens the rim.
The improvement in the Ferrari Portofino M’s aerodynamic performance is underscored by a slash on the front bumper that flows into the design of the flanks, lending visual harmony to the side view of the car. Thus, the signature Portofino side scallop finds its visual counterpart on the Ferrari Portofino M’s front bumper, which has been resculpted to accentuate the car’s dynamic profile.
