"How did we get here?"
Body & Exterior
Nicolas Joseph invented the first car, Powered by Steam!
Nicolas Joseph Cugnot
(1725 - 1804).
Max Speed 2 ½ MPH !
The vehicle had to stop every ten to fifteen minutes to build up steam power
first person to get into a
motor vehicle accident
TATA foundation of what would grow to become the TATA Group was laid by Jamsetji Nusserwanji Tata
1832 - Electric Car
Who we are and What we do. . . . . .
Body Design and Advances - from the 1st car to the present day
Design Drivers - What effects us day to day? Our Constraints
Platform Strategy - What are we doing to plan for the future?
Something that closes or seals something!
Closures refers to anything that opens or closes on the BIW, this incorporates;
Latches & Hinges
Handles (Int & Ext)
Keys and Locking
Check Straps and Gas Struts
What Is BIW?
BIW - Body In White
Highly tuned structure
First car Made from 100% Steel
E.G. Budd Manufacturing
Made in Hamtramck, Michigan
Could be painted in 1 day
Compared to 3-8 Weeks
1st Practical Car
The Benz Patent
Made in Hamtramck, Michigan
Tubular Steel Frame
1914 Dodge Tourer
From Wood to Steel
Using wood as a material was a limiting factor of design.
The introduction of metal fabrication technologies introduced new possibilities of using sheet metal.
Sheet metal was stronger and more durable.
Morgan Motors of Great Britain are the only manufacturer left to use wood for purposes other than decoration.
Two long rails running the length of the vehicle
The engine mounted between the rails
Axles suspended underneath
Lack of diagonal bracing
The 1st Model T is Produced
Ford Motor Company introduces the Moving Assembly Line
Independent front suspension
What is a Monocoque?
Mono - One, Coque - Shell
Definition: An aircraft or vehicle structure in which the chassis is integral with the body.
AKA: unitary construction or uni-body.
Citroen produce their first car - Type A
Half the cars in the world are Model T Fords
Tatra T11 - Backbone Chassis
4 gears with lever directly on top of the gearbox!
Hans Ledwinka created the design
Similar to body on a frame
Prop shaft enclosed
Thatcham Insurance Ratings
Political & Social Implications
Ford-built V8 engine
First true Spaceframe Chassis
Built by aviation engineer and journalist William B. Stout
What is a Spaceframe?
Definition: A three-dimensional structural framework which is designed to behave as an integral unit and to withstand loads applied at any point
Load transfer is primarily axial — tension or compression
Chrysler Imperial Airflow
Improved visibility and styling.
The first British all-steel body is produced by the Pressed Steel Company for the Morris Isis Six
Land Rover Series 1
All Aluminium body
Green and Only Green!
Britain's first front wheel drive production car is introduced by Alvis
There are now 35 million motor vehicles on the world’s roads
American car production falls to just 139 vehicles as war production requirements take over
Modern Laminated Glass
Laminated glass replaced toughened glass
Invented in 1903 by the French chemist Edouard Benedictus, inspired by a laboratory accident.
Ford used a form of laminated glass as early as 1929
UK law in the 1980s
The ‘MOT’ test is introduced by Ernest Marples
Pontiac GTO Endura Bumper
Rover and Alvis are absorbed into the Leyland Motor Corporation
MGB & US Regs
NHTSA introduced a regulation for low-speed impacts
NHTSA – National Highway Traffic Safety Administration
1974 MGB changes from chromed bumper bars to rubber bumpers. To meet legal requirements for imports.
Renault and Peugeot start production of common components
First Standardized Crash Test
NCAP (New Car Assessment Programme)
35MPH Frontal Impact
Japan’s monthly production output of 200,000 cars, makes it the world's second biggest motor manufacturer.
The Golf GTi debuts at the Frankfurt International Motor Show establishing a new market sector later known as the ‘Hot Hatch’.
‘Aero Style for the masses’
Cd of 0.34
(The Cortina it replaced was 0.45)
Coefficient of Drag
Styling led to the knickname “Jelly Mould”
A bonded windscreen (direct glazing) can increase the body stiffness of a car from 40% to 50% as shown by Daimler tests on the Mercedes C – Class.
Bitter strikes at British Leyland provoke chairman Sir Michael Edwardes to threaten "Return to work or lose your jobs."
Offset Crash Test
Ford takes over Jaguar Cars
Consumer demand for Star Rating
Up to 5 Stars awarded
New 2016 tests
Aston Martin introduce the DB7
Influential Milestones from the 1st Car to Today
Drivers for change
Worlds 1st mass produced CFRP Body Structure
Pure Electric Range
CFRP - Carbon Fibre Reinforced Plastic
Is it just a "bag of bits"?
The high level key drivers in order of ranking for a modular platform are as follows:
Platform Market Euro/India
Vehicle Segments and Variants
Carryover Parts (Engine, HVAC, Suspension System) / Hard Points
Manufacturing Facilities (Location, Single/Multiple line, Flexible tooling)
Legislation and Future Proofing
Platform Key Drivers
Birmetals got is name from being based in Birmingham
What is Platform Strategy
Standardisation of manufacturing and product development elements, driving cost and timing.
Development of an under body for Cross segment applications,
Reduce overall number of platforms,
Physical grouping of underbody and powertrain systems / subsystems,
Part numbering consistency,
Body assembly sequence consistency,
Final area assembly sequence consistency,
Tooling consideration across a Platform,
Simplified engineering and purchasing organisation
Who Uses Platform Strategy
No real strategy until 1992 with some (badge sharing) with mainly only A surface changes
Platform 1992 - 2001(BIW) : Part sharing across one class only
Pure Platform - 2001- 2007 Underbody and strategic part sharing across more than one class
Modular architecture, 2007 – Present Collection of modules, parts and logistical/assembly strategy
Platform Strategy History
Drivers vs Time
Number of Drivers
VW (MLB +MQB)– Modular Architecture
(MQB) Modularer Querbaukasten German for modular transverse matrix
(MLB) modular longtitudinal matrix
MLB was introduced in 2007 for E segment cars.
Volkswagen Group moved to a Modular Architecture Platform Strategy in 2012 with MQB for B-D segment cars
VW (MQB)– Modular Architecture
All Volkswagen Group MQB platform cars share:
pedal box positioning, i.e. driver H-point relative to the Door
However the platform is flexible enough to allow individual models to have a variety of:
"How did we get here?"
We have looked at:
The evolution of the body
The drivers that effect us day to day
How we are planning for the Future
