6. Multibrand-Event Energy and propulsion alternatives are many – what will dominate in the future? Electric Vehicle Energy ResourcesEnergy Carriers Propulsion Systems Fuel-Cell Electric Hydrogen Gaseous Fuels Gaseous ICE Biomass Natural Gas CoalNuclear Other Renewables (Solar, Wind, Hydro) Electricity Electric Vehicle Battery Electrification Plug-In Hybrid ICE Conventional ICE: Gasoline / Diesel Oil Liquid Fuels ICE Hybrid

7. Multibrand-Event “The key as we see it at GM is energy diversity – being able to offer our customers vehicles that can be powered with many different sources of energy. We must – as a business necessity – develop alternative sources of propulsion, based on alternative sources of energy, in order to meet the world’s growing demand for our cars and trucks.” Rick Wagoner Chairman and CEO General Motors Corporation Geneva Motor Show, 6 March 2007 GM is committed to energy diversity

8. Multibrand-Event GM will continue to improve internal combustion engines Gasoline engines – Higher levels of fuel economy, power and torque Diesel engines – Increased power and torque with reduced emissions and Noise / Vibration / Harshness Engine downsizing and turbocharging is a key trend Transmissions: Higher levels of fuel economy and performance Past Achievements: First to meet Euro 4 with Astra 1.7 diesel First to meet diesel particulate filter requirements with Vectra 1.9 diesel

9. Multibrand-Event Saab BioPower: Market Leader in Europe Europe: Saab European market leader with 40% market share, ahead of Ford and Volvo North America: GM market leader – more than 2 Million vehicles on the road Brazil: 90% of the vehicles sold by GM are FlexPower vehicles Beyond Europe, ethanol is a major success for GM

10. Multibrand-Event Opel – strong player with CNG applications Two major local markets: Italy and Germany Total European market volume 45,000 vehicles/annum 60% Italy, 30% Germany, 10% Sweden, Switzerland and Austria Opel 2nd largest manufacturer
