1.8L TSI Engine

1.8L TSI Engine:
Smaller, Lighter, Turbocharged!
When it comes to engines, smaller, lighter, and more efficient are the
road signs to the future. Volkswagen launches a new turbocharged direct
injection engine built at a new, state-of-the-art engine facility in Mexico
for the North American market: the Gen 3 1.8L TSI®.
The New 1.8L TSI Delivers:
• More Torque
• Higher Estimated Fuel Economy
• Lower Emissions
• Stronger Acceleration
• Better Throttle Response

Volkswagen of America, Inc. believes
this information to be correct at the time
of release. Specifications, standard and
optional equipment are subject to change

Technical Features
The NEW 1.8L TSI®
Known internally as EA888, the Gen 3 1.8L TSI engine debuts
in the U.S. market with a number of significant technological
advances. This all-new 1.8L TSI engine is no relation to
Volkswagen’s previous 1.8L turbocharged engine.
Friction Reduction
• Smaller main bearings
• Balance shafts with roller bearings
• Lowered, optimized pressure for the oil circuit and oil pump
• Reduced tensioner forces in belt drive system
Lightweight
Key weight-reduction factors:
• Thin-walled engine block (3 mm thick)
• Crankshaft with four counterweights instead of eight
• Cylinder head with integrated exhaust manifold
• Integrated exhaust gas cooling system
• Lighter turbo housing
• Plastic lower oil pan
• Use of aluminum bolts
Thermodynamics
The 1.8L features an integrated exhaust manifold in the cylinder
head, which saves weight and allows for a comparatively
compact and light turbocharger. The exhaust manifold is water
cooled to lower the exhaust gas temperature on its way to the
turbocharger. This lets the engine run more efficiently, especially
under load, without the risk of overheating the turbo.
The cooling system is designed to:
• Reach optimal operating temperature more rapidly to reduce
emissions
• Minimize internal friction
• Provide quicker heater response for passenger comfort

FSI Intake Manifold
• The 1.8L engine’s intake manifold uses direct injection technology for
maximum efficiency
• The fuel straight injection (FSI) system has fuel pressure as high as
200 bar – about 50 bar more than most injection systems
• High pressure helps achieve low emissions and efficient combustion.
Compact Turbocharger
Volkswagen’s turbo engines are designed to combine strong low-end
torque with maximum power output. The 1.8L TSI achieves maximum torque
at a low engine speed of only 1,500 rpm. The 1.8L engine’s turbocharger
features:
• Lightweight die-cast aluminum housing
• Twin-scroll compressor rotor, milled from a solid block for greater highspeed strength and better acoustics
• A new electric wastegate actuator – faster and more precise than a
standard pressurized actuator – designed to maintain optimal boost
levels from the turbo
• Internal water cooling and oil cooling/lubrication
• Integrated exhaust manifold cooling also helps keep the turbo’s
temperature within operating parameters
The turbo compresses the engine’s intake air and passes it through an
intercooler to help make it even more dense for stronger combustion.
Valvetrain
• Double overhead camshaft, chain-driven
• Each cylinder has two intake and two exhaust valves
• Variable intake timing helps ensure smooth operation
and maximum performance at all engine speeds

Key Advantages
1.8L TSI Selling Points
Now that we know some of the technological highlights, what do you tell your
customers about the new 1.8L TSI engine? What are its strong points?
Stronger acceleration
Although the 1.8L TSI has the same horsepower
rating of 170 that the 2.5L engine has, the new
engine is lighter and produces more torque. That
means that acceleration is significantly stronger. In
the Jetta, 0-60 mph takes only 7.3 seconds with a
manual transmission, compared to an estimated 8.6
seconds in a Jetta powered by the 2.5L engine.
High torque at low rpm
The 1.8L TSI engine produces more torque than the 2.5L engine.
From engine speeds as low as 1,600 rpm, the 1.8L TSI “High”
variant with automatic transmission generates its impressive
maximum torque of 200 lb.-ft. The 2.5L engine is rated at 177
lb.-ft. of torque at a much higher engine speed: 4,250 rpm. Lowspeed torque provides a more satisfying driving experience,
quicker acceleration, and faster throttle response.
1.8L TSI Engine • 4
High fuel economy
The 1.8L TSI is designed for maximum fuel efficiency. The new 1.8L TSI is estimated to provide
better fuel economy than the 2.5L engine that it replaces. For example, the 2014 Jetta (with the
1.8L TSI and 6-speed automatic) EPA estimates are 26/36 mpg (city/hwy) compared to 24/31
EPA mpg (city/hwy) with the 2.5L engine – that’s a 16% improvement in highway fuel efficiency!
The Passat, Beetle, and Beetle Convertible also boast improved fuel economy estimates
compared to their 2.5L ratings, giving you even more exciting news to share with your customers.
Regular gas
Many turbocharged engines require premium fuel for
maximum performance. Thanks to variable valve timing,
water-cooled exhaust manifold, and other factors, the
1.8L TSI was designed to run on regular gas, an important
cost savings for owners.
Lightweight
Thanks to the weight savings described in the Technical
Features section of this module, the 1.8L TSI weighs less
than the 2.5L 5-cylinder used previously. The lighter
weight 1.8L engine means faster acceleration, improved
handling dynamics, and better fuel economy than the
2.5L engine.
1.8L TSI Engine • 5
Lower emissions
With a pre-catalyst positioned close to the engine to reach operating
temperatures quickly, along with a secondary catalyst, the 1.8L TSI
is clean and green. It meets or exceeds emission standards in all 50
states, and qualifies for Bin5/EPA and PZEV California Emissions
standards.
Built in North America
This year, Volkswagen inaugurated
its 100th plant worldwide with a new,
environmentally advanced engine
factory in Silao, Mexico. This engine
plant localizes production as part
of Volkswagen’s ongoing $5 billion
investment in the North American
market. With a maximum annual
capacity of 330,000 engines, the
new factory will supply engines for
Volkswagen models produced in
Puebla, Mexico, and Chattanooga, TN.
