Just of interest what is im3 rex runtime readings all of your i3 rex's? We have a 2016 with 104K Km (65K Mi) on the clock and the rex has done 11k km (6.8k mi) on the clock. does BMW have a basic expected runtime on the rex? The 647 cc engine as fitted in the i3 REx is derated compared to the engine of the same displacement in the C650 GT; the REx engine develops 34 hp; 34 PS (25 kW) and 41 lb⋅ft; 5.6 kg⋅m (55 N⋅m) at 4,300 RPM, achieving compliance with Euro-6 emissions standards [111] compared to the 59 hp; 60 PS (44 kW) (at 7,500 RPM) and 49 lb⋅ft; 6.7.

The BMW i3 REx is a unique vehicle that blends electric power with a gasoline range extender, making it a popular choice for eco-conscious drivers who still want the flexibility of a traditional engine. However, when it comes to reliability, there are a few key components that every owner should keep an eye on. Understanding how these parts perform over time can help you make informed.

What does REx mean on BMW i3? The i3 was offered in two flavors; BEV (Battery Electric Vehicle) and REx (Range Extender). The former used an electric motor and a battery, nothing else. The latter featured a small gasoline engine under the trunk to help provide some battery juice when the state of charge got too low.

CAR reviews new BMW i3 REX We live with i3 Range Extender 94Ah EV battery range on test Month 12 of our BMW i3 long-term test: the verdict Almost exactly one year after it arrived on CAR's fleet. That optional range extender (REx for short) is used solely to power a generator that delivers electricity to the battery and the traction motor that actually power the car. That makes the BMW i3.

The BMW i3 REx features a unique plug-in electric powertrain supplemented by a small gasoline-powered range extender engine - a compact 2-cylinder unit sourced from BMW's motorcycle division. The BMW i3 REX 120 Ah stands out with its remarkable efficiency of 11 kWh/100 km kWh/100 miles and a substantial range of 203 km (126 miles) miles on a single charge. The BMW i3 is generally reliable for daily city driving, especially in its electric form, but long-term ownership comes with some caveats.

While build quality and tech are impressive, battery degradation, high repair costs, and limited service networks can affect overall dependability. This is a comprehensive guide about are bmw i3 reliable. I believe the Volt engine can either generate for the battery or couple to the drivetrain depending on conditions.

The big difference is that the i3 is designed to be electric only with the engine as a "range extender" for backup purposes. I believe most i3 Range Extender users rarely use the extender during daily commutes, etc.
