The BMW 325i is also making its debut in spring 2005: Maximum output is 160 kW/218 bhp at 6,500 rpm, maximum torque 250 Nm/184 lb-ft between 2,750 and 4,250 rpm. Engine displacement, as the model designation indicates, is 2.5 litres.
BMW 320i with high-performance four-cylinder power unit
The new BMW 320i is the most powerful four-cylinder in the range. Based on the two-litre straight-four so far featured in the BMW 318i, this power unit is also equipped with VALVETRONIC and dual-VANOS variable camshaft adjustment, developing maximum output of 110 kW/150 bhp at 6,200 rpm and maximum torque of 200 Nm/147 lb-ft at 3,600 rpm. This accelerates the BMW 320i from 0-100 km/h in 9.0 seconds and gives the car a top speed of 220 km/h or 136 mph. Fuel consumption in the composite EU cycle is 7.4 litres/100 km or 38.2 mpg Imp. This increase in performance over the previous engine already acknowledged as very dynamic is attributable to detailed optimisation of the intake and exhaust ducts.
The range of petrol engines in the BMW 3 Series will naturally be enlarged step-by-step, a 'basic' four-cylinder supplementing the line-up in autumn 2005.
The 320d continuing the successful story of the Sports DieselIn the BMW 320d diesel turns into pure dynamics. Featuring BMW's second-generation common-rail technology as well as an exhaust gas turbocharger with variable turbine geometry, this outstanding four-cylinder develops supreme output of 120 kW/163 bhp and equally supreme torque of 340 Nm/251 lb-ft at 2,000 rpm. In terms of both drive comfort and dynamic performance, the 320d is definitely 'best in segment'.
The car's acceleration obviously reflects this superior power, with acceleration from 0-100 km/h in 8.3 seconds. Top speed is 225 km/h or 140 mph, and fuel consumption in the composite EU cycle a mere 5.7 litres/100 km or 49.6 mpg Imp. And it goes without saying that the BMW 320d complies in full with the EU-4 emission standard.
Six-speed gearboxes on all models
All models come as standard with manual six-speed transmission or, as an option, with six-speed automatic. Benefitting from the additional gear, the closer gear ratios, as well as the larger increment between the smallest and largest gear, the driver is able to shift gears at exactly the right point for a smooth, ongoing surge of engine power. This is a particular advantage when setting off, with first gear being laid out for more muscle, traction and pulling force. In all, the new BMW 3 Series is more dynamic, accelerates more quickly, and offers an even higher top speed. And all this is on less fuel than before.
