Liebherr celebrated its 50 year presence in the United States. To mark this special anniversary, the R 938 featured a special red, white and blue paint scheme reminiscent of the stars and stripes of the American flag. This special design created by Auguste Bartholdi, a native of Colmar, France, included the Statue of Liberty – an internationally known New York City icon.

Hyundai's first electrically powered compact excavator to be introduced to the market. The R18E uses a Li-ION battery (LFP type), generating a power capacity of 19.6 hp (14.6 kW). Its battery charger is rated at 3 kW, with a free-voltage range of 100-230 v AC.

With an operating weight of 3,800 lb (1,725 kg), digging depth of 7 ft 11 in (2,405 mm), and dump height of 8 ft 10 in (2,680 mm), the R18E is powered by an induction-type motor, with a one-hour current rating of 225 amps.

Digital control is provided through a microcontroller. It can operate up to eight hours on a full charge and can be fully recharged in five hours. As an electrically powered machine, the R18E produces no carbon emissions, and operates at 70.1 dB of sound.

Powered by Cummins BM4.4E flexible battery modules (5.9 hp, or 4.4 kW, each), the Hyundai R35E excavator prototype is designed to support a full work shift and charge in less than three hours.

The excavator contains eight BM4.4E modules connected in a series configuration to provide a total energy of 47 hp (35 kW).
