The engine has been the character-defining feature of every 911 since 1963. And on the new 911 Targa 4 models, it’s no different. The 6-cylinder boxer engine, positioned low down at the rear of the car, succeeds in uniting two characteristics that are normally mutually exclusive – performance and efficiency. Only by doing so is it possible to increase power output whilst simultaneously reducing fuel consumption and CO2 emissions.
At the heart of all this are intelligent efficiency-enhancing measures such as the auto start/stop function and direct fuel injection (DFI).
And then there’s the crucial weight factor. The engines are of a light-alloy construction, making them lightweight and yet structurally rigid. The result is comparatively low fuel consumption and a long service life.
Both engines are also equipped with VarioCam Plus – a two-in-one engine concept for adjusting the intake camshafts and switching the lift of the intake valves. This results in instant acceleration, exceptional smooth running performance and an extraordinary level of tractive power with a comparatively low level of fuel consumption.
The engine of the new 911 Targa 4 develops 257 kW (350 hp) at 7,400 rpm and a maximum torque of 390 Nm at 5,600 rpm. When combined with the 7-speed manual gearbox, it accelerates from 0 to 100 km/h in just 5.2 seconds and reaches a top speed of 282 km/h.
On the S model, the figures speak for themselves: the 3.8-litre boxer engine develops 294 kW (400 hp) at 7,400 rpm and a maximum torque of 440 Nm at 5,600 rpm. When equipped with the optional Porsche Doppelkupplung (PDK), the new 911 Targa 4S completes the 0 to 100 km/h sprint in just 4.6 seconds and can continue on to a top speed of 294 km/h.
