Peugeot has been using a range of BMW-sourced four-cylinder engines in its cars for years and now sister brand Citroen has confirmed its new models will also get the British-built engines. The engines come in several different flavours, including turbo and naturally aspirated versions, and range from 1.4 to 1.6L in displacement.
Peugeot uses the engines to power its 207 and 308 models but Citroen hasn’t confirmed which of its cars will use the BMW engines. According to WhatCar?, the new engines will likely debut in the Citroen C5 by the end of the decade. In the Mini, the engines produce outputs of 120,150 and 175hp, and includes direct-injection and variable valve timing technologies.
The key reason for the move is to allow Citroen to take advantage of BMW’s EfficientDynamics engine stop-start technology, which the French carmaker hopes to eventually roll out across its entire lineup. The system Citroen plans to use will be the same as the current design in the Mini, where the engine cuts out while stationary and restarts when the driver selects first gear.

Why don’t say BMW uses PSA engines? These engines may be produced by BMW, but they are possibly developed by PSA.
Actually these engines were engineered by PSA, due to the lack of experience of BMW staff in four cylinder engines.
Paulo Pinto, get real, its the FWD packaging that BMW needs help with! BMW pumped out 1500hp from a 1.5L Turbo motor in the 80’s, they were one of if not the first to use intelligent thermostats on their 4 cylinder motors in the 90’s to improve efficiency and fuel consumption & BMW is the motor manufacturer winning engine of the year awards year after year! In truth the motors in question use a combination of technology strengths from all 3 manufacturers in order to reduce development costs. One aspect BMW supplied was the variable valve timing technology.. that’s just one of the contributions. Read about the motor before you volunteer a useless comment! Paulo Pinto, have you heard of the BMW K1200RS & its family?
