Roewe, a Chinese automaker under the SAIC Motor Corporation, has achieved a remarkable feat by setting a new Guinness World Record. The Roewe D7 DMH, a plug-in hybrid midsize sedan, successfully covered a staggering 2,208 kilometers without refueling or recharging.
This record-breaking journey took place over four days, traversing diverse terrains from the cities of Lanzhou to Urumqi. The route included challenging conditions such as gravel roads, snow, ice, and significant altitude changes, showcasing the D7 DMH's versatility and efficiency.
The D7 DMH's plug-in hybrid powertrain, comprising a 1.5-liter gasoline engine and a 201 hp electric motor, proved to be highly efficient. The engine boasts an impressive thermal efficiency of over 43%, contributing to the vehicle's exceptional fuel economy. The official combined range of the D7 DMH is 1,400 kilometers, but the record-breaking journey exceeded this figure by a significant margin.
It's worth noting that the driver's skill and driving style played a crucial role in achieving this remarkable result. The average fuel consumption during the record attempt was a mere 2.49 liters per 100 kilometers, demonstrating the potential for significant fuel savings with efficient driving techniques.
As the automotive industry continues to evolve, we can expect to see more impressive feats from plug-in hybrid vehicles. With Chinese automakers leading the charge in PHEV technology, it's likely that future records will be broken, pushing the boundaries of efficiency and range.
