Tyres

The Alfa 159 Sportwagon's excellent behaviour on the road is also a result of the tyres which achieve the best balance between handling and comfort. To guarantee controlled slip on corners, combined with an excellent capacity to absorb obstacles, the Alfa Romeo engineers and suppliers have developed special larger tyres, up to 235/45 R 18.


Powerful, elastic engines that respect the environment

At its launch, the Alfa 159 Sportwagon is equipped with three petrol and three turbodiesel engines, all combined with new mechanical six-speed gearboxes, with short strokes, precise engagement and low loads. A 1.8 litre engine delivering 140 bhp will be available after the launch, while automatic transmissions and a Selespeed robotised gearbox will also be proposed on some versions, all with six speeds.

The 3.2 JTS (260 bhp), 2.2 JTS (185 bhp) and 1.9 JTS (160 bhp) were developed to respect the brief from the Alfa Romeo engineers and represent the brand's interpretation of the direct injection petrol engine, which translates into enjoyable driving and high performance for the customer. The three engines adopt the direct injection JTS (Jet Thrust Stoichiometric) combustion system, which produces brilliant engine performance. The 3 engines deliver the quality one expects from Alfa Romeo, having been fine-tuned on the Balocco test track, while final assembly takes place in the Alfa plant in Pomigliano. All the JTS engines obviously meet Euro 4 limits. The Alfa 159 Sportwagon is also available with three Multijet turbodiesel engines, the 1.9 8v JTDm (120 bhp), 1.9 16v JTDm (150 bhp) and the new 2.4 20v JTDm (200 bhp), which guarantee excellent power and torque deliveries in all driving conditions, combined with low fuel consumption. They are all combined with 6-speed gearboxes (including the automatic transmission that will be available on the 150 bhp 1.9 JTDm after the launch), true jewels of automotive engineering that confirm Fiat Auto's leadership in this field. When it developed the Multijet system, the Fiat Group set its stamp on the diesel engine market. The three Multijet engines of the Alfa 159 Sportwagon obviously respect Euro 4 limits, and incorporate a DPF (particulate trap) that eliminates fine dust in line with the limits currently envisaged for future Euro 5 legislation. It is a 'for life' system that does not need to be regenerated with additives, and will be eligible for tax incentives.


The new 260 bhp 3.2 JTS V6

The Alfa Romeo 'cuore sportive' really beats in the new V6 3.2 litre petrol engine, which delivers 260 bhp. It represents a significant departure from Alfa Romeo's previous V6 engine, as well as its natural evolution. The new JTS engine is capable of a power delivery of 260 bhp (20 bhp or 8% more than the previous 3.2 V6 Q4); peak torque of 322 Nm at 4,500 rpm (+33 Nm, an increase of more than 11%); a specific power of 60 kW/l and specific torque of 100 Nm/l; a significant increase in torque at low speeds to improve the smooth delivery (approximately 30 Nm more than the previous 3.2 V6 engine, starting from 1500 rpm); maximum revs of 7,200 rpm; minimal maintenance (hydraulic tappets and timing gear with chain drive); low weight (aluminium cylinder head and crankcase); and Euro4 exhaust emissions limits. With this equipment, the Alfa Romeo 159 Sportwagon can reach a top speed of 237 km/h and accelerate from 0 to 100 km/h in 7.2 seconds.


Main technical features

The new 6-cylinder engine of the Alfa 159 Sportwagon continues the strategy begun with the 4-cylinder engines, and adopts the JTS (Jet Thrust Stoichiometric) direct injection system. This is an original Alfa Romeo concept that injects the fuel directly into the combustion chamber with a stoichiometric mixture optimised to enhance performance, but also guarantees low consumption and respect for the Euro4 emissions limits.

Numerous important components have been designed from scratch and are exclusive to the Alfa Romeo V6 engine. To start with, the cylinder head is aluminium and has 4 valves per cylinder, 2 camshafts per bank with the 'Twin Phaser' continuous variable valve timing (intake and exhaust) already adopted on Alfa Romeo 4-cylinder engines and now applied on a 6-cylinder engine for the first time. Variable valve timing allows the phase angle on both cams to be varied by 50 degrees, maximising performance on the one hand, because the best phase can be chosen at all engine speeds, and reducing consumption and emissions with partial loads on the other.
