03 MARKET ANALYSIS
Answers of the six questions: Who What Where When Why REQUIREMENTS How
Who uses the product? Where is it used? When is it used? Mainly as corporate Focus on Western and Everyday use (work use) representative car and for emerging markets and for Track days the middle class (China, India,...) Why choose it? What requirements How is the product A status of superiority over from the product? used? Combination of the others in the range, performance and safety The average user will transpires sportiness with (ADAS), Autonomous bring the image of the an aggressive look, but also driving, High perceived company but also enjoy quality and a focus on the car for track days a sense of \"elegance\" and for its appearance driver’s comfort and luxury
Price in line with the luxury range Customization High perceived quality Long range hybrid powertrain High performances Safety Comfort Attractive appearance Autonomous driving Smart Accessibility Efficiency Visibility Reliability High technology
What are the customer’s needs and expectations? Know your customers Alessandro Gruppi Dealer Manager Porsche Center Bologna
Dependence Matrix Relationship of dependency present between each row element and the column element, distinguishing between: ● null (blank box) ● weak (1) ● medium (3) ● strong (9)
Matrix of Relative Importance The element in the row is more important than the element in the column? ● row < column (0) ● row = column (1) ● row > column (2)

2D Architecture The idea of our product meets the characteristics from benchmarking and what-how matrix CUSTOMIZATION & PRICE PLUG-IN HYBRID ENGINE PROS: every car is different and it’s value increase PROS: more power, range CONS: more components, and possibility to enter in colors and detail variety limited areas. CONS: isn’t full electric Electric engine because the infrastructure and long trips don’t allow that WIDE WINDSCREEN PROS: more light and vision to outside CONS: in summer can enter more heat, otherwise in winter can enter more cold PERFORMANCE & COMFORT NOTE: Safety is not mentioned because is PROS: customers want implied performances and comfort at the same time CONS: dimensions and particular specific components
3D ARCHITECTURE (Chassis) and Digital Mock-Up
3D Architecture – The Chassis The frame of the car with casted, extruded and sheet parts
3D Architecture - Chassis FEM analysis STRAIN STRESS LOADS Loads considered: ❑ Engine (E63-AMG) = 2000 N ❑ 5 seats = 750 N each passenger ❑ Battery (Tesla) = 5400 N ❑ Tank = 700 N
DMU: Digital Mock-Up Chassis with some components of the car in order to undestrand volumes
