Alfa Romeo 156: Twin Spark, JTD and V6 engines and trims
Alfa Romeo 156 (1997–2007) — a sporty mid-size sedan and estate, the Sportwagon, still beloved by enthusiasts. We look at the engines, trims, and what to check when buying a used car.
The 156 in brief
The Alfa Romeo 156 was launched in 1997 and immediately stood out with its expressive design: hidden rear door handles and a striking 'triangular' front. It was produced as a sedan, and from 2000 as the Sportwagon estate.
The car is praised for its driving pleasure, distinctive design, and engine variety. Like most older Alfas, it demands more attentive maintenance, so a clear service history is crucial for buyers.
Which 156 to choose
Early cars (up to 2003) have a front-wheel-drive layout and simpler interiors, while the facelifted model (from 2003) got a new front bumper, different headlights, and an improved cabin.
If you're after the best-condition car, consider the facelifted version with better-refined engines. Enthusiasts might prefer the 156 GTA with its 3.2 V6 engine, but it's pricier and demands particularly meticulous maintenance.
Engines and gearboxes
The petrol Twin Spark engine range includes 1.6, 1.8, and 2.0-litre versions, with power outputs roughly ranging from 120 to 155 hp. There's also the 2.5 V6 (around 190 hp) and the 3.2 V6 in the GTA model (around 250 hp).
Diesel JTD engines — 1.9 JTD (around 105–150 HP, later models are Multijet) and 2.4 JTD with five cylinders (around 136–175 HP). They are economical, and the later Multijet engines are more powerful and modern.
Transmission options include manual, as well as the robotised Selespeed and automatic gearboxes. Ensure they operate smoothly.
What to check when buying a used 156
The front suspension is one of the model's well-known weak points: worn-out control arm bushes and ball joints can cause clunking and uneven pulling. Test the car on an uneven road and listen for clunks.
Check if the timing belt has been replaced (especially important for V6 and Twin Spark engines), and how the Selespeed gearbox works if the car has one. In diesel JTDs, check for any power issues with the engine.
Inspect the body and sills for rust, as well as the electrical equipment — older cars can have minor faults here.

Frequently asked questions
Which Alfa Romeo 156 engine is the most reliable?
Many experts prefer well-maintained 1.9 JTD and 2.0 Twin Spark engines. However, the condition of the specific car is more important than the engine type.
Is it worth buying a 156 with Selespeed?
Selespeed is a robotised gearbox that can cause additional problems. If you still opt for such a car, test drive it and ask for the service history.
What's the difference between the sedan and Sportwagon?
The Sportwagon is an estate with a larger boot, while the mechanics and trim levels are essentially the same. Your choice depends on how much space you need.
