Currently reading: Updated BMW i3 gets longer range
New 120Ah battery replaces 94Ah unit of the current model; it's been shown at the Paris motor show

BMW's i division has upgraded the electric-powered BMW i3 with a new battery that is claimed to extend its range by almost 30% under everyday driving conditions. The revised BMW  EV has been shown at the Paris motor show.

The new 120Ah lithium ion unit replaces the 94Ah battery used by the existing i3 and brings a 9.2kWh increase in energy capacity for the quirky five-door hatchback, at 42.2kWh.

In the standard 168bhp i3, it provides a range of 193 miles, or up to 34 miles more than the predecessor model, under the newly introduced Worldwide Harmonised Light Vehicle Test Procedure (WLTP).

In the more performance-orientated 181bhp BMW i3s, the new battery is claimed to bring a 25-mile improvement in range at an official 177 miles under WLTP.

Under everyday driving conditions, BMW says the new 120Ah battery provides both i3 models with a realistic range of up to 162 miles, or 37 miles more than that quoted for the existing i3 with its 94Ah battery.

BMW i is remaining tight-lipped about the weight of its latest battery. However, it claims the 0-62mph times for the rear-wheel-drive i3 and i3s remain virtually unchanged, at 7.3sec and 6.9sec respectively, with the 50-75mph times put at 5.1sec and 4.3sec.

The new battery, developed in partnership with Samsung, retains the same dimensions as the unit it replaces, enabling it to be packaged in the same dedicated space within the floor of the i3.

BMW puts the recharge time of the battery at 15 hours on regular 2.4kW mains electricity. This is reduced to 3.2 hours from the optional BMW i wallbox, which provides three-phase charging at 11.0kW. On a fast-charging DC system operating at 50kW, the recharge time is a claimed 42 minutes.

Since its introduction in 2013, the i3 has been offered with three different batteries, including the original 60Ah unit and the 94Ah unit of the existing model, with respective energy capacities of 22.6kWh and 33kWh.

In addition to the new battery, BMW has also announced a new optional sports package for the i3 as part of changes being brought to the 2019 model. It includes sports suspension with a widened front track, a 10mm reduction in ride height, uniquely tuned springs, dampers and anti-roll bars and 20in wheels.

Further changes include new exterior colours, revised upholstery combinations for the interior, optional adaptive LED headlights and new iDrive infotainment functions, including a wi-fi hotspot capable of supporting up to 10 devices.

Good but....

Increased range can only be a good thing but there is a huge gulf between the i3 range and the Hyundai Kona electric range which is quite embarrassing for BMW given their premium positioning. Early reports I've read suggest the Kona's range of 300 miles seems achievable. But with 300 miles on a single charge now possible for less than Tesla money, range is becoming less of an issue and charging times more important.

Lost occasion?

Had BMW increased the capacity of the REX ( range extender ) tank , say to 30 liters, the car would have been also attractive to new customers circles .They would certainly accepted the reduction of the boot size ( equipment would have to be stocked behind instead of the front boot ( if one did not find room elsewhere?).

Range extender range

I too thought the same. But apparently in some markets a larger capacity isn't allowed, otherwise the car isn't considered a ULEV, so there would be tax penalties. I believe that the tank "capacity" is limited by the car's electronics not the actual tank volume, and a slighly higher capacity is allowed when the larger battery is fitted.
