After we’ve seen the US bound model, VW is now introducing the Euro spec version 2011 Volkswagen Jetta which is mostly oriented towards efficiency rather than performance.
The 2011 Volkswagen Jetta Euro spec model measures 4.64 m in length, which makes it 6.7 cm longer than its predecessor, and as far as motorisation option, choices include two diesel and three petrol engines.
The diesels are a 1.6-litre 4-cylinder TDI producing 105 HP (77 kW) and a 140 HP (103 kW) 2.0-litre unit, while the petrol option include a 200 HP 2.0 TSI, a 1.2 TSI with 105 hp and a 1.4 TSI which can delivering either 122 HP (90 kW) or 160 HP (118 kW).    
All engine options available on the Euro spec 2011 Volkswagen Jetta, except for the 105 HP TSI, come with a dual-clutch DSG transmission, and as far as fuel consumption figures, the most efficient version will be the 1.6 TDI BlueMotion which requires 4.2-litres/100 Km (56 US mpg) and has CO2 emissions of 109 g/Km.   
Pricing for the 2011 Volkswagen Jetta Euro spec version starts at 20,900 Euro and reaches 29,950 Euro, while the three available trim levels are Trendline, Comfortline and Highline.
Volkswagen press release :
Now in Europe too:
Volkswagen introduces new era of world bestseller Jetta
Completely new Jetta at prices from €20,900 in Germany
Jetta 1.6 TDI BlueMotion Technology consumes just 4.2 l/100 km
Wolfsburg / Munich, 26 October 2010 – In the USA it is the most
successful car of any European producer: the Jetta. Between the East and
West coasts of America, up to 110,000 vehicles of this model series are
sold annually. Americans value the Jetta as a highly safe and sporty
saloon with “German Engineering.” In June, Volkswagen unveiled – in an
event receiving international attention with stars like Katy Perry at
the centre of New York’s Times Square – a completely new generation of
the world bestseller with over 9.6 million units built so far. Now, the
most impressive Jetta ever is also launching in Europe. This heralds a
new era for this model series between Helsinki and Rome, Istanbul and
Lisbon. The latest version of “the” saloon of the compact class is
expected to carry over its US success to Europe.
This Volkswagen has the potential to do just that. Never before has a
Jetta had this much sports appeal, this much fuel efficiency or this
large a size. The times when the saloon was simply derived from the Golf
are a thing of the past. From now on, these two successful models will
go their own ways. The new Jetta, now significantly longer (4.64 metres
long instead of the previous 4.55 metres), is very appealing as a
high-end, spacious and sporty saloon with maximum active driving
Prof. Dr. Martin Winterkorn: "We have completely
retuned the technology and styling of the Jetta. That is why our number 1
selling car in America will also be extending its position in Europe
from now on." The Chairman of the Board of Management of Volkswagen AG
continues: "At prices from €20,900, we are offering a Jetta that will
add a new dimension of quality to the saloons of the compact class."
in fact, this Volkswagen – available in Trendline, Comfortline and
Highline equipment versions – takes an enormous leap forward in concept
and styling. As mentioned, the saloon’s design is no longer derived from
the Golf; instead, it follows its own line of styling. This makes the
Jetta a strong and independent model series just like the Eos and the
Tiguan. Designers and engineers also came up with an entirely new
interior. The five-seat saloon’s rear seating layout is significantly
more spacious (6.7 cm gain in legroom) thanks to the car’s longer
wheelbase – a result of the increased vehicle length. With these
dimensions, the Jetta ideally fills the gap between the compact Golf
(4.20 metres long) and the new large Passat (4.77 metres long).
Uncompromising efficiency
its smallest engines are truly great successes. Take the example of the
1.6 TDI with 77 kW / 105 PS: In the BlueMotion Technology version, this
common rail turbodiesel only consumes 4.2 l/100 km (equivalent to 109
g/km CO2). Consider the 1.2 TSI that also outputs 77 kW / 105 PS and has
BlueMotion Technology: This direct-injection turbo petrol engine only
requires 5.3 l/100 km (equivalent to 123 g/km CO2), which is exceptional
considering that this is a saloon with petrol engine that can move at
190 km/h. As already noted, the Jetta 1.2 TSI costs €20,900 in the
Trendline version. The base price of the Jetta 1.6 TDI Trendline with
BlueMotion Technology: €23,475. Additional power levels: a TDI with 103
kW / 140 PS and three TSIs with 90 kW / 122 PS, 118 kW / 160 PS and 147
kW / 200 PS. So, the Jetta is being driven exclusively by charged,
high-tech, direct-injection engines. All engines except the 105 PS TSI
may be combined with a dual-clutch transmission (DSG).
Three equipment lines
The Trendline equipment line is still the entry-level model to the
world of the Jetta. When it comes to safety, standard equipment includes
six airbags (with an optional eight), five crash-optimized head
restraints (on front seats with anti-whiplash design), daytime running
lights, belt fastening detection, automatic hazard flasher lights that
activate with hard braking, Hill Climb Assist and ABS with braking
assistant and ESP with trailer stabilisation.
Exterior features of
the Jetta Trendline include details such as 205 tyres on 16-inch steel
wheels, electrically adjustable and heated door mirrors with integrated
turn signals and green tinted heat-insulating glass. Inside, comfort and
convenience are upgraded with details such as climate control
(Climatic), dust and pollen filter, radio remote control of central
locking, outside temperature indicator with road icing warning, chrome
bezels for the air vents, multifunctional display (MFA) and a
height-adjustable driver’s seat (with fabric seat covers in "Cardeol"
Comfortline: The medium equipment version, the
Comfortline, is offered at prices from €22,600 (Jetta 1.2 TSI with 77 kW
/ 105 PS). This model’s exterior is distinguished by chrome accents in
the radiator grille and 16-inch, five-spoke "Mambo" alloy wheels.
the Jetta Comfortline is upgraded with details such as storage pockets
on the backrests of the front seats, centre armrests (with storage
compartment in front), 8-way adjustment of driver and front passenger
seats, comfort seats with elegant fabric upholstery in "Sienna" design,
woven floor mats, the RCD 210 radio-CD system, a Chrome Pack (including
rotary light switch and control dial for climate control) and what is
known as the Small Leather Pack (leather-trimmed steering wheel,
gearshift grip and parking brake grip) as well as black accents ("Black
Pyramid"). Also standard: the Park Pilot (front and rear), lowering of
the passenger side door mirror when reversing and four reading lamps (2
in front, 2 in rear).
Highline: The most exclusive Jetta version
is the Highline equipment line. It may be ordered in combination with
TSI engines from 90 kW / 122 PS (base price: €24,575) as well as all TDI
power levels (base price of 77 kW / 105 PS: €25,875). Exterior features
beyond those of the Trendline and Comfortline: 17-inch alloy wheels
(ten-spoke "Porto" type), chrome frame around lower air intake screen,
chrome trim under the side windows, headlight cleaning system and front
fog lights with cornering lights.
A Winter Pack (including heated
front seats and heated windscreen washer nozzles) helps to get through
the coldest season of the year. Inside, features that refine the top
model include sport seats with fabric covers ("Gloss") and artificial
leather, particularly elegant accents ("Iridium Printed" pattern) and an
automatic climate control (Climatronic).
