How does it compare?
Speed
The SOR NS 12 electric sets a steady pace with a top speed of 80 km/h (50 mph), positioning itself squarely among urban warriors. The Mercedes eCitaro is a smidge faster at 70 km/h (43 mph), while the BYD K9 and Proterra Catalyst E2 match the SOR on speed. The Volvo 7900 Electric lags slightly behind, pushing 75 km/h (47 mph). Suffice to say; no one’s winning the Indy 500 here, but they’ll get you through city traffic smoothly.
Range
The SOR NS 12 electric flexes significant muscle, boasting a range of 240 km (149 miles). The Proterra Catalyst E2 crushes the competition with a staggering 440 km (273 miles). The BYD K9 rolls in with a respectable 250 km (155 miles), while the Mercedes eCitaro hits a commendable 150 km (93 miles). The Volvo 7900 Electric offers about 200 km (124 miles). The range is varied, but the SOR stands solidly in the middle.
Power
Under the hood, the SOR NS 12 electric packs a robust 242 kWh battery while the Mercedes eCitaro flaunts a slightly less potent 243 kWh module. The BYD K9 steps up with a 324 kWh battery, and the Proterra Catalyst E2 rockets ahead with a beefy 660 kWh. The Volvo 7900 Electric, meanwhile, fits a modest 300 kWh. For raw staying power, the Proterra has a clear lead, but the others reduce the gap.
Charging Time
Charging the SOR NS 12 electric is a breeze, clocking in at 3 hours using a fast charger. The Mercedes eCitaro shadows slightly longer at 4 hours. The prolific BYD K9 similarly takes 4 hours, while the star-studded Proterra Catalyst E2 recharges in just 2.5 hours. The Volvo 7900 Electric isnt slacking, needing about 3 hours. If you’ve got a lunch break, your bus can almost be ready to hit the road again.
Price
Now, talking what may deter buyers—the price. The SOR NS 12 electrics pricing information might be elusive, but rivals sit clear. The Mercedes eCitaro hovers around $495,000 (£407,000 or €470,000). The BYD K9 offers a more tempting smile at approximately $410,000 (£337,000 or €389,000). Our indomitable Proterra Catalyst E2 asks for a kings ransom of $700,000 (£575,000 or €660,000). The nuanced Volvo 7900 Electric positions at $450,000 (£369,000 or €428,000). Shelling out fair judgement depends on the full cribsheet.
Sounds like a playground showdown, with each vehicle airing its strengths and quirks—but for urban mobility with green ethics, youre choosing from a golden roster.
