In somewhat an expected move, BMW has released another state of tune for their 4 cylinder TwinPower turbocharged engine series, the N20. Complementing the current "20i" and "28i" guises is the new "25i" guise, which kicks out a familiar 218bhp@5000rpm and 310Nm@1350-4800rpm. In comparison, the "20i" version delivers 184bhp/270Nm while the "28i" version pumps out 245bhp/350Nm.
The N20 is a new series of small capacity engine utilizing its TwinPower turbocharged concept. The engine makes use of twin-scroll turbocharger, high precision injection, Valvetronic and double VANOS. It is part of BMW engine downsizing initiative where the punch of the bigger capacity engine is delivered by forced-fed small capacity engine, while retaining the small engine fuel efficiency.
The engine was launched with the updated BMW 1 series as part of the extended engine availability for the 5 door version of BMW compact hatchback. In this application, the 125i is capable of 6.5 seconds sprint to 100 km/h for the 8-speed automatic version en route to its 243 km/h top speed. Fuel efficiency is quoted as 6.4L/100km and CO2 emission of just 154g/km. It is then just a matter of time before the new F30 325i and F10 525i badge make an appearance!
In a simultaneous move, the 1 Series has been given new diesel engine too. The first one is the 116d EfficientDynamics Edition, while the other one is 125d. The 1.6L 116d ED emits an impressive 99g/km of CO2 and deliver 116bhp@4000rpm and 260Nm@1750-2500 rpm. Diesel consumption is quoted as 3.8L/100km. The performance figure is 10.5 seconds century sprint and 195 km/h top speed. This engine is offered too on F30 316d where performance is quoted slightly differently with 11.3 seconds 100 km/s sprint and 202 km/h of top speed.
Power-hungry environmentalist should however look for 125d. With a petrol-rivalling 218bhp@4400rpm, and V8 rivalling 450Nm of torque delivered between 1500-2500 rpm. The 2.0L turbo-diesel engine is sufficient to sprint the F20 to 100 km/h in 6.5 seconds and a 240km/h of top speed. Fuel consumption is rated at 4.8L/100km and 126g/km of CO2 for the 8 speed automatic version. More after the jump.
BMW has also took the opportunity while updating the F20 1 series engine inventory to introduce the M Sport package for its small hatchback. The M Sport package consists of 10mm lower M Sport suspension with stiffer shocks and sturdier anti-roll bar to sharpen the handling fronts, while customary bumpers and skirting complete the outlook. 17" and 18" M light alloy with staggered tyres are available too.
The interior has been suitably upgraded too. The package consist of components such as aluminium door sill cover strips with M emblem, M leather steering wheel with multifunction buttons, M footrest and M gearshift lever, an M Sport exclusive sports seats with Hexagon Anthracite fabric/Alcantara with contrast stitching in Royal Blue.

Thanks to reader Burn (a loyalist BMW fans with both E34 and E60 currently in his garage) for suggesting the video.
Rock on!!!
