How does it compare?
Speed
When it comes to speed, the HEULIEZ GX 337 ELEC stretches its legs to 70 km/h (43 mph), a practical pace for urban layouts. The BYD K9 and Proterra Catalyst E2 slightly edge it out at 80 km/h (50 mph) but lets be honest, in the stop-start of city traffic, youre not exactly setting land speed records. The New Flyer Xcelsior CHARGE maintains a democratic 65 km/h (40 mph), while the Volvo 7900 Electric also rides the sensible bus lane at 70 km/h (43 mph).
Range
Range anxiety? Not here. The HEULIEZ GX 337 ELEC boasts a respectable 300 km (186 miles), allowing city loops without the constant need for juice. And yet, the Proterra Catalyst E2, with its near frightening range of 560 km (350 miles), sets the gold standard. The BYD K9 offers a healthy 250 km (155 miles), while the New Flyer Xcelsior CHARGE holds tight with 225 km (140 miles). Meanwhile, the Volvo 7900 Electric impresses with a sprightly 200 km (124 miles), but for many city routes, that’s more than sufficient.
Power
Turning to sheer brawn, the HEULIEZ GX 337 ELEC flexes its 160 kW (215 hp) muscles robustly. The BYD K9 pulls slightly ahead at 180 kW (241 hp), while the Proterra Catalyst E2 swells to a hulking 225 kW (302 hp). The New Flyer Xcelsior CHARGE holds its ground at 200 kW (268 hp), and the Volvo 7900 Electric steps in with a serviceable 150 kW (201 hp).
Charging Time
Lets talk juice. The HEULIEZ GX 337 ELEC replenishes in about 3-5 hours. Comparing, the Proterra Catalyst E2, that overachiever, licks the plug in less than 2 hours. The BYD K9 and New Flyer Xcelsior CHARGE go cup-for-cup with 3-4 hours, while the Volvo 7900 Electric prefers a leisurely 4-6 hours to replenish.
Price
Ah, the wallet. Here’s an interesting turn. The price for the HEULIEZ GX 337 ELEC is currently under wraps, but one can estimate from competitors like the BYD K9 at around $450,000 (£360,000, €420,000) and the Proterra Catalyst E2 hovering about $750,000 (£600,000, €700,000). The New Flyer Xcelsior CHARGE tags along at about $400,000 (£320,000, €375,000), and the Volvo 7900 Electric brings up the rear at a more modest $350,000 (£280,000, €330,000).
So, there it is. From speed to power, range to recharge, these electrifying beasts jostle for supremacy, each armed with their own blend of capabilities and flair!
