“It’s FUN TO DRIVE,

OFFERS GREAT FUEL

ECONOMY—CRUZE IS

just incredible.”

Mike Katerberg, Assistant Chief Engineer, talks about

the balance between performance and fuel economy, the

excitement of a variable displacement oil pump, and why

the Chevy turbocharger is changing the rules.

“In order to design a very fuel-efficient engine, you have

to start with the basics. You have to get the combustion

right, you have to make sure the airflow and the cooling

are right. You design the structure around that. We

started with proven technology, like the available small

displacement ECOTEC® 1.4-liter engine with four

cylinders. Then we turbocharged it to get 138 horsepower.

So when you need performance, you get the added boost

from the turbocharger. When you’re driving normally

or just cruising, it offers great fuel economy—up to

42 MPG highway

on Cruze Eco.

“One unique feature we have on Cruze is the variable

displacement oil pump. The oil pump is the heart of the

engine. It’s what lubricates the bearings and helps keep

things cool. On most engines, the faster the engine spins,

the more oil is pumped. On Cruze, we were able to get

feedback from the engine on how much oil it needs and

tailor the pump to deliver only that much. That saves

energy and optimizes fuel economy. It’s exciting to see

that kind of fuel economy in a car this size.

“Cruze also uses the Chevy Oil Life Monitoring System

to track how the vehicle is operating and the condition of

the oil. It tells you when you have to change it. So at any

time, you can look at the percentage of oil life left. It saves

you money and is respectful of the environment because

you’re not changing oil when you don’t need to, but you’re

still protecting your engine.

“I drive a lot of cars. Right now, I’m driving a 2012

Cruze automatic. It’s fun to drive and offers great fuel

economy

— Cruze is just incredible.”
