BRILLIANT

Behind the strong personality of its styling, Fiat Grande Punto offers a comprehensive range of excellent engines featuring advanced technology and generous performance. There are two petrol engines (1.2 8v delivering 65 bhp and the 1.4 8v delivering 77 bhp) and four Multijet turbodiesel units: the 75 bhp or 90 bhp 1.3 16v, and the 120 bhp or 130 bhp 1.9 8v. Each has different features which are exploited in full in combination with 5 or 6 speed mechanical gearboxes, which stand out for their generosity, sparkling character, high performance and sophisticated technology. The features they share are outstanding reliability and respect for the environment: all the engines respect Euro 4 emissions limits.

All Fiat Grande Punto engines are built by Fiat Powertrain Technologies, the Group's new operating sector. FPT groups together all Fiat Auto's activities in the fields of innovation, research, planning and production of engines and gearboxes for all types of application, from cars to commercial vehicles, boats and agricultural machinery. More than 3000 work in the FPT research centres in eight different countries and they help to make this sector a great centre of technological excellence and constant innovation.


Diesel engines: the history of Fiat's achievements

The 75 bhp and 90 bhp 1.3 16v Multijet

The Fiat Punto could not fail to mount the 1.3 16v Multijet - the smallest and most advanced second generation direct injection Common rail diesel engine - now with an important novelty: a new version with a variable geometry turbo is making its debut. With this turboboost system, the 1.3 16v Multijet delivers a power output of 90 bhp (66 kW at 4000 rpm) and peak torque of 20.4 kgm (200 Nm at 1750 rpm). That is not all. With the 90 bhp 1.3 Multijet, the Grande Punto achieves outstanding performance: it has a top speed of 175 km/h and accelerates from 0 to 100 km/h in just 11.9 seconds. Even consumption is among the lowest in this segment: 5.9 l/100 km in the urban cycle, 3.9 l/100 km out of town and 4.6 l/100 km in the mixed cycle.
The new engine differs not only for the different turboboost system (on the 75 bhp 1.3 Multijet it is provided by a fixed geometry turboblower), but also for other changes. The combustion system has been modified, increasing the permeability of the inlet and exhaust manifolds, reducing turbulence in the combustion chamber and varying the geometry and the compression ratio from 18:1 to 17.6:1. The emissions control system envisages an EGR valve with electric actuation managed directly by the engine control system, a heat exchanger to cool the recirculating exhaust gas (EGR), and a 'close coupled' catalytic converter, which guarantees respect for EC Phase 4 emissions limits.

The performance of the 1.3 Multijet is also excellent; it delivers a power output of 75 bhp (55 kW at 4000 rpm) and peak torque of 19.4 kgm (190 Nm at 1750 rpm). With this engine the Grande Punto has a top speed of 165 km/h and accelerates from 0 to 100 km/h in 13.6 seconds, with excellent combustion: 5.9 l/100 km in the urban cycle, 4.0 l/100 km out of town and 4.7 l/100 km in the mixed cycle.

These are the differences between the 75 bhp and the 90 bhp versions. On the other hand they both share the engine architecture: 4 cylinders in line, 1248 cc, with a bore of 69.6 mm and a 'long' stroke of 82 mm. There are four valves per cylinder, driven directly by twin overhead camshafts via rocker fingers with a roller. That is not all. The 1.3 Multijet 16v is a masterpiece of technology in miniature: complete with all its accessories, it weighs just 130 kg, and is also small in size, just 50 centimetres long and 65 centimetres high, with the components laid out to take up as little space as possible.

Designed to criteria of maximum rationality, efficiency and reliability, the engine is capable of excellent performance, and is practically built 'for life': it was designed to travel 250,000 km without any maintenance to the mechanical components. What is more, the oil change intervals have been extended from 20,000 to 30,000 km (the 1.3 Multijet 16v uses low viscosity oil, which means more fuel economy, and it respects the environment).

This compact, technologically sophisticated engine is also environment-friendly, because it meets Euro 4 emissions limits even without a particulate trap, which is available on request for certain markets.
