The Alfa Romeo 159 represents a significant evolution in Alfa’s mid-size sedan lineage, replacing the 156 and setting new standards in design, safety, and structural rigidity. Produced from 2005 to 2011, the 159 carried forward Alfa Romeo’s passion for driving pleasure while offering a more solid, premium feel than its predecessors. As a used car, the Alfa Romeo 159 remains an appealing option for enthusiasts who desire Italian design, a refined driving experience, and individuality rarely found in mainstream models.
Exterior Design and Dimensions
The Alfa Romeo 159 was designed by Giorgetto Giugiaro in collaboration with Alfa’s own Centro Stile, resulting in a bold and elegant appearance that still turns heads today. The car’s front end is dominated by the signature V-shaped Alfa grille, flanked by triple headlamp clusters that emphasize its sporty character.
The car’s proportions and stance give it a muscular and purposeful look, aided by a long bonnet and a short rear overhang. Compared to the 156, the 159 is noticeably larger and feels more substantial on the road.
Dimensions:
-
Length: 4,660 mm
-
Width: 1,828 mm
-
Height: 1,417 mm
-
Wheelbase: 2,700 mm
-
Curb weight: 1,400–1,600 kg (depending on engine and trim)
These larger dimensions translate into a more spacious cabin and improved crash safety but also contribute to the car’s increased weight, which has implications for performance and fuel efficiency. The Alfa Romeo 159’s body is constructed using a mix of high-strength steel and aluminum, enhancing rigidity while maintaining balanced weight distribution.
Engine Range and Technical Specifications
The Alfa Romeo 159 was offered with a wide range of engines during its production, catering to both petrol and diesel buyers. All engines are transversely mounted and paired with either a six-speed manual or six-speed automatic transmission, with the high-performance versions featuring Q4 all-wheel drive.
Petrol Engines:
-
1.8 MPI (140 hp, 175 Nm): Entry-level naturally aspirated engine, reliable but underpowered for the car’s weight.
-
1.9 JTS (160 hp, 190 Nm): Offers better mid-range power with direct injection technology.
-
2.2 JTS (185 hp, 230 Nm): More responsive, but known for timing chain wear if not properly maintained.
-
3.2 V6 JTS (260 hp, 322 Nm): The flagship petrol engine co-developed with General Motors, featuring Q4 all-wheel drive. It delivers strong acceleration and a refined sound, though it lacks the musical tone of Alfa’s earlier “Busso” V6 engines.
Diesel Engines (JTDm Common Rail):
-
1.9 JTDm (120–150 hp, 280–320 Nm): Economical and popular, suitable for long-distance driving.
-
2.0 JTDm (136–170 hp, 350–360 Nm): Later models with improved emissions and stronger mid-range torque.
-
2.4 JTDm 20V (200–210 hp, 400–450 Nm): A powerful five-cylinder diesel with smooth delivery and impressive performance, especially in the Q4 versions.
Transmission options included:
-
6-speed manual: Available across most engines, offering precise shifts and a sporty feel.
-
6-speed automatic (Aisin or Q-Tronic): Smooth and convenient, but slightly less engaging.
-
Selespeed (early versions): An automated manual system, rare and often avoided due to reliability concerns.
Performance varies by model, with 0–100 km/h times ranging from around 10.0 seconds for smaller diesel engines to 7.0 seconds for the V6 Q4 variant. Top speeds range from 200 km/h to 240 km/h, depending on the configuration.
Chassis, Suspension, and Handling
The Alfa Romeo 159 was engineered on the Premium Platform, a collaboration between Alfa Romeo, Lancia, and Saab, emphasizing structural rigidity and driving precision. The platform uses a double-wishbone front suspension and a multilink rear setup, providing a balance of ride comfort and dynamic control.
Steering is electrically assisted and finely tuned for responsiveness, giving the driver confidence and precision through corners. The suspension’s geometry allows the 159 to maintain excellent stability at high speeds, while still offering agile handling for a car of its size.
Braking performance is handled by ventilated discs on all wheels, with four-wheel ABS, EBD (Electronic Brake Distribution), and ASR (Anti-Slip Regulation) as standard. The Q4 all-wheel-drive system, available on the 3.2 V6 and select diesel models, distributes torque between front and rear axles via a Torsen C differential, ensuring superior traction and composure on slippery roads.
Despite its weight, the Alfa Romeo 159 feels planted and secure, particularly on winding roads where its balanced chassis and direct steering come into play. Ride comfort is firm but not harsh, making it suitable for both enthusiastic driving and everyday commuting.
Interior and Comfort Features
Inside, the Alfa Romeo 159 offers a driver-centric cabin characterized by elegant Italian design and solid build quality. The dashboard is angled toward the driver, with deeply recessed instruments and metallic trim accents that convey a sporty, premium feel.
Interior materials vary depending on trim level, ranging from durable cloth to full leather upholstery. Higher trims, such as the Distinctive and TI (Turismo Internazionale), include aluminum pedals, sports seats, and red stitching.
Key interior features may include:
-
Dual-zone automatic climate control
-
Cruise control and steering wheel-mounted controls
-
Bluetooth connectivity and CD/MP3 audio system
-
Rain and light sensors
-
Electrically adjustable mirrors and windows
-
Optional satellite navigation and Bose sound system
Cabin space is significantly improved over the 156, offering generous front legroom and a comfortable seating position. Rear passenger space is decent, though the sloping roofline slightly reduces headroom. Boot capacity stands at 405 liters for the sedan and around 445 liters for the Sportwagon version.
Reliability and Maintenance Considerations
As a used car, the Alfa Romeo 159 has proven more reliable than earlier Alfa models, thanks to its improved build quality and modernized components. However, like any Italian performance-oriented vehicle, it demands proper maintenance.
Common issues include:
-
Timing chain wear on 2.2 JTS petrol engines, leading to rattling noises or poor timing.
-
EGR valve and DPF clogging on diesel models, particularly with short-distance driving.
-
Front suspension wear, especially on control arm bushings and ball joints.
-
Electrical gremlins, such as malfunctioning sensors or intermittent warning lights.
-
Turbocharger wear on high-mileage diesel engines.
Regular servicing using high-quality fluids and parts is essential. Timing belt replacement intervals for diesel models are typically every 100,000 km or 5 years, while petrol engines may require chain inspection and tensioner maintenance.
Fuel economy varies: diesel versions average 6.0–7.0 L/100 km, while petrol models range from 8.0–11.0 L/100 km depending on driving style and engine size.
Driving Experience and Road Behavior
The Alfa Romeo 159 offers a refined and rewarding driving experience that blends comfort and performance. The steering is precise, the chassis well-balanced, and the ride quality composed even on uneven roads.
Petrol engines provide smooth power delivery and a distinctive Alfa sound, especially the 3.2 V6, which adds a level of excitement few competitors can match. Diesel models, particularly the 2.4 JTDm, deliver strong torque and effortless long-distance cruising capability.
The Q4 all-wheel-drive system adds confidence in all weather conditions, though it slightly increases fuel consumption and maintenance costs. Overall, the 159 combines elegance and dynamism in a way that few mid-size sedans manage.
Buying Advice for a Used Alfa Romeo 159
When purchasing a used Alfa Romeo 159, prospective buyers should:
-
Verify complete service records, especially timing belt or chain maintenance.
-
Check suspension and steering components for play or noise.
-
Inspect DPF and EGR function on diesel variants.
-
Test electronics thoroughly, including climate control and infotainment.
-
Prefer models with Q-Tronic automatic or well-maintained manuals.
Opting for later production models (post-2008) is advisable, as they benefited from weight reduction and improved engine management systems.
Final Thoughts
The Alfa Romeo 159 remains one of the most beautifully designed sedans of its generation, combining Italian passion with modern engineering. As a used car, it offers exceptional value for those seeking style, comfort, and dynamic handling. While it requires attentive maintenance, a well-cared-for Alfa Romeo 159 rewards its owner with an engaging drive and timeless aesthetic appeal. For drivers who appreciate individuality and craftsmanship, the 159 stands as one of Alfa Romeo’s finest modern classics.
