[1] With its headquarters in Northampton, UK and sister company in Plymouth, Michigan, United States, the company specialises in the design, development and testing of electrified powertrain systems and provides a broad spectrum of engineering services to its global customer base.

The ownership of MAHLE Powertrain can be traced back to Cosworth, which was owned by the Vickers Group from March 1990.

This newly formed Cosworth Technology Group consisted of the engineering headquarters at Northampton, the engine assembly and machining facilities at Wellingborough, and the low volume, aluminium alloy, and sand casting facility at Worcester (retaining the famous Coscast process capability within the group).

It specialises in the design, development, testing, and manufacturing of electrified powertrain systems and high efficiency internal combustion engines.

In addition to the head office in Northampton, UK, it also operates sites in Munich, Germany and Plymouth, Michigan.

Some projects are stand-alone and may employ specialists from a single department; others involve engineers from all disciplines within the company.

At their Northampton (UK) site, MAHLE Powertrain has extensive engine, battery and vehicle testing facilities which are used to develop performance and reliability and reduce CO2 emissions and fuel consumption.

Bench tests initially proved that it was capable of delivering abundant power and torque with very low fuel consumption in a high durability package.

The engine employs four cylinders which are arranged in a square (U4) pattern using two crankshafts geared together using a configuration known as 'double leading Alpha'.
