GM eAssist Technology

• 2013 Malibu Eco

– Expected to achieve 25 mpg city/37 mpg highway

– 25% better fuel economy than traditional powertrain system

• Buick – “You don’t keep running when you are stopped, so why should your car’s engine?”

• Light-electrification system

– Standard on Buick LaCrosse and offered on Buick Regal

– 25 mpg city/36 mpg highway

• The system starts with a 2.4L Ecotec 4-cylinder engine and a next-gen 6-speed automatic transmission

– Adds an electric motor-generator (15kW)

– Adds 115V lithium-ion battery

• This combination stores energy and saves fuel

eAssist Components

• Improvement in fuel economy comes from these powertrain energy saving features:

– Engine off at idle

– Extended fuel cutoff on decelerations

– Regenerative braking

– Electric boosting

– Intelligent charging/discharging of the lithium-ion battery

• Additional vehicle energy savings comes from:

– Efficient tires

– Under body aerodynamic panels

– Front-end active airflow management

eAssist Fuel Saving Features

• Today is the start of a revolution in the auto industry

– For 100 years, vehicles have been mechanically-driven and petroleum-fueled

– Moving to vehicles that are driven and fueled by electricity

• This kind of revolution changes societies

Electric Vehicles Changing Industry

• In a class by itself — first mass-produced Extended Range Electric

Volt Reinventing the Automobile’s DNA

2011

• Combines a high-voltage lithium-ion battery pack with an advanced electric drive unit

• Electric Mode — Volt can drive initially on electricity for a range of 35 miles*

• Extended Range Mode — Gas-powered generator turns on and produces electric energy for approximately 344 additional miles of driving range

How Volt Works

*EPA estimated 35 miles initial range based on 93 MPGe (electric);

actual range varies with conditions

actual range varies with conditions

• The Volt proves electric driving can be spirited

– Top Speed — 100 mph

– Torque — 273 lb.-ft.

– 0-60 mph in less than 9.0 seconds

– Quarter mile in less than 17 seconds

Volt Performance

• Uses less energy per year than average household refrigerator and freezer

Volt Battery is Very Efficient

• Recharge for less than a cup of coffee (approx. $1.50 per day)

• Volt driver would pay less than 3¢ per mile of electric driving, less if charged during off-peak hours

• In contrast, at $3 to $4 a gallon, a conventional vehicle would cost between 10¢ and 13¢ per mile

Compared to Gasoline

vs.

• Cadillac Converj concept to become production car called Cadillac ELR

– Luxury touring coupe with extended-range electric vehicle technology

• The modern vision of the personal luxury 2+2

Expanding EREV Technology

• Spark EV all-electric vehicle will be sold in select U.S. and global markets in 2013

– Offers an all-electric option to customers with predictable driving patterns

• advanced nanophosphate lithium-ion battery packs

2013 Chevrolet Spark EV

• Fuel cells are right choice for customers who need:

– More passenger and cargo-carrying capability

– Ability to travel longer distances at highway speeds

– Great performance and fuel economy

– Rapid re-fueling

Hydrogen Fuel Cell Vehicles

• Zero petroleum

• Zero greenhouse gas emissions

• Zero tailpipe emissions

• Triple the range of electric vehicles

• No overnight charging

Benefits of Hydrogen Fuel Cells

• Compared to an internal combustion engine, this system:

– Is more than twice as efficient

– Promises equivalent durability, range (300 miles) and performance

– Has 60% fewer part numbers

– 90% fewer moving parts

– And offers similar refueling time (~3 minutes)

GM’s Fuel Cell System

• Packaged in space of a traditional 4-cylinder engine

• Hydrogen storage system and high voltage battery placed for maximum crash protection

• Commercial production expected within the decade

Rechargeable Energy Storage

• Real-world product evaluations

– Project Driveway (2007 to 2010)

– GM-Hawaii collaboration with production-intent vehicle (ongoing)

• 30-month program started in 2007

• 100+ vehicles in the hands of retail and commercial customers

• Largest-ever market test of fuel cell vehicles

• Amassed more than 2.3 million miles

– Included nearly 20,000 refuelings

– Saved 1.2 million pounds of CO2 from being released into atmosphere

Project Driveway

• Hawaii’s major energy gas provider to make hydrogen available to Oahu’s one million residents later this decade

– GM to provide vehicles for test market

• GM also collaborating with three U.S. military organizations in Hawaii by providing 15 fuel cell vehicles for use and evaluation
