BMW has revealed a few details on its upcoming 2017 1 Series and 2 Series models. The most significant of these is the introduction of the latest generation turbocharged inline four and six-cylinder engines to the smallest models in its line-up. To be launched in July this year, the 230i Coupé and Convertible will get a new 2.0-litre turbocharged four-cylinder engine, which mated to a six-speed manual or an eight-speed automatic transmission, will put out 252 horsepower, which is seven horses more than before. The 230i Coupé will do the 0 to 100kph sprint in 5.8 seconds, while the 230i Convertible will take 6.1 seconds to do this. The automatic transmission variants shave two-tenths of a seconds from these times in both variants.
Meanwhile, the performance variants of the 1 and 2 Series, which used to be called M135i and M235i, will now be called M140i and M240i, and will be powered by a 3.0-litre six-cylinder turbocharged engine that’s good for 340 horsepower and 500Nm of torque. The new engine brings faster throttle response, with peak torque now available between 1,500rpm to 4,500rpm. This upgrade has brought these models close in performance to the full-blown 2011 BMW 1 Series M Coupé. The standard rear-wheel drive M140i and the M240i accelerate from 0 to 100 kph in 4.8 seconds, when equipped with a manual gearbox and in 4.6 seconds with an automatic ‘box, while the all-wheel drive M140i xDrive and the M240i xDrive, both of which are available only with an automatic transmission, do this in 4.4 seconds. Along with these performance improvements, BMW claims to have achieved a 7 per cent reduction in fuel consumption as well.
The M Performance models also come with M Sport suspension that’s stiffer and lower, 18in alloy wheels wearing Michelin Pilot Super Sport rubbers, upgraded M Sport brakes with fixed multi-piston callipers, variable sports steering and upgraded aerodynamics.
