Page 4 of 8 New four-cylinder gasoline engine with two levels of performance.
Displacing 2.0-litres, the four-cylinder direct – injection power unit in the new
BMW 1 Series is entering the market in two levels of power and performance.
The most significant difference in engine technology is the use of a switchable
intake manifold on the more powerful version, the light-alloy power unit
developing maximum output of 125 kW/170 hp in the BMW 120i, an
increase in power by 15 kW or 20 hp over its predecessor. Maximum torque
of 210 Nm/155 lb-ft, in turn, comes at an engine speed of 4,250 rpm
accelerating the new three-door model to 100 km/h in 7.7 seconds (five-door
model: 7.8 seconds) and giving both models a top speed of 224 km/h or
139 mph. Average fuel consumption of the new BMW 120i in the EU test
cycle, finally, is 6.4 litres for 100 kilometres, equal to 44.1 mpg Imp.
Maximum output of the new BMW 118i is 105 kW/143 hp, that is 10 kW/14 hp
more than before. In this performance version, the 2.0-litre four-cylinder
develops maximum torque of 190 Nm or 140 lb-ft at an engine speed of
4,500 rpm. The increase in engine power in the new BMW 118i gives
both the three- and five-door model a top speed of 210 km/h or 130 mph.
Acceleration to 100 km/h, in turn, comes in 8.7 seconds (five-door model:
8.8 seconds). Average fuel consumption in the EU cycle, finally, thanks to
High Precision Injection, is just 5.9 litres/100 km, equal to 47.9 mpg Imp
on both models.
The fourth gasoline model also providing remarkable performance in its
five-door configuration is the 1.6-litre four-cylinder in the BMW 116i. This
modern power unit featuring double-VANOS develops maximum output
of 85 kW/115 hp and peak torque of 150 Nm/111 lb-ft, giving the car a top
speed of 200 km/h (124 mph) and acceleration to 100 km/h in 10.9 seconds.
Fuel consumption of the BMW 116i, finally, is just 7.5 litres/100 kilometres,
equal to 37.7 mpg Imp.
New generation of BMW turbodiesel power units.
The new BMW 1 Series is the first BMW to feature the new 2.0-litre fourcylinder
turbodiesel. Significantly lighter than the former power unit thanks to
its aluminium crankcase, this engine comes in two power stages providing
a substantial improvement of performance over the former models. This
enhanced performance accompanied by an appropriate reduction in fuel
consumption is the result of modifications in the design of the combustion
chamber, air supply and direct common-rail fuel injection, as well as the
redesigned turbocharger with its particular blade geometry.
Both power units come as standard with a diesel particulates filter positioned
close to the engine and therefore easily outperform the Euro 4 emission
standard.
In the new BMW 120d the four-cylinder develops maximum output of
130 kW/177 hp – an increase by 10 kW/14 hp over the former engine. Peak
torque, in turn, is 350 Nm/258 lb-ft at 2,000 rpm, ensuring superior power
and pulling force also from low engine speeds. Top speed of both the threeand
five-door model is 228 km/h or 141 mph, and the new BMW 120d
accelerates to 100 km/h in just 7.5 seconds (five-door model: 7.6 seconds).
At the same time fuel consumption in the EU test cycle is down to an
average of just 4.9 litres/100 kilometres on both the three- and five-door
model, equal to 57.6 mpg Imp.
Maximum output of the new BMW 118d is up by an even more significant
15 kW/21 hp to 105 kW/143 hp, with peak torque increasing by 20 Nm to a
new level of 300 Nm/221 lb-ft at 2, 000 rpm. This gives the car a top speed of
210 km/h or 130 mph (both the three-door and five-door model), with the new
BMW 118d accelerating to 100 km/h in 8.9 seconds (five-door model: 9.0
seconds). And despite this increase in output and performance, average fuel
consumption of both models in the EU test cycle is a mere 4.7 litres/
100 kilometres, equal to 60.1 mpg Imp.
Given the performance characteristics and sound-deadening on BMW’s
modern diesel engines, the average motorist – or the motorist not driving the
car that much for example, when renting the car – will hardly notice any
difference between the diesel model and the gasoline version. Precisely this is
why the new BMW 120d and the new BMW 118d come with a precautionary
tank-filling system ensuring that only the diesel pump at a filling station fits into
the fuel tank opening: The tank opening in these models has a special filler
cap contoured to interact only with a standardised diesel filler pump. In other
words, the cap will not open whenever the driver inadvertently tries to fill in
gasoline.
