The 767-200ER has a higher maximum takeoff weight than the 767-200
The Boeing 767 is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The 767-200ER is an extended-range model that was first offered by Boeing in 1984. It has a higher maximum takeoff weight (MTOW) and greater fuel capacity than the 767-200.
The 767-200 typically seats 216 passengers and has a range of 3,900 nautical miles (7,200 km; 4,500 mi). In comparison, the 767-200ER seats 181 passengers and has a range of 6,590 nautical miles (12,200 km; 7,580 mi). The extended range of the 767-200ER is due to its increased fuel capacity and higher MTOW, which is up to 395,000 lb (179,000 kg).
The additional fuel capacity of the 767-200ER is achieved by using the center tank's dry dock to carry fuel. In contrast, the non-ER variant (the 767-200) uses what are called cheek tanks, which are two interconnected halves in each wing root with a dry dock in between.
The 767-200ER was the first 767 to complete a non-stop transatlantic journey and broke the flying distance record for a twinjet airliner in 1988. It has been popular with international airlines operating medium-traffic, long-distance flights.
The 767-200ER also has a slightly longer wingspan than the 767-200, which provides higher-altitude cruise performance and expansion room for future stretched variants. The 767's fuselage width is midway between that of the 707 and the 747 at 16.5 feet (5.03 m). This width allows for seven-abreast seating with two aisles and produces less aerodynamic drag than previous wide-body designs.

The 767's fuel efficiency is improved by raked wingtips
The weight of a fully fuelled and loaded Boeing 767 depends on the variant in question. For example, the 767-200ER has a higher maximum takeoff weight (MTOW) of 395,000 lb (179,000 kg) compared to the initial 767-200. The 767-400ERX has an even higher MTOW of up to 465,000 lb (210.92 t).
Now, onto the 767's fuel efficiency and its relation to raked wingtips:
The 767-400ER was the first Boeing commercial airplane to use raked wingtips as a wingspan extension. These wingtips are highly swept back, extending the 767's original 156-foot wingspan to 170 feet, 4 inches (51.9 m). The 7-foot-8-inch (2.4 m) wing extensions are designed to increase the aerodynamic efficiency of the wing, providing more lift without lengthening the wing. This results in improved cruise efficiency and range.
The raked wingtips offer several advantages over traditional wing extensions or winglets. Firstly, they are lightweight and simple to integrate, bolting directly onto the existing wing structure without requiring additional modifications. This efficiency of design and economy of structure affords the 767-400ER more gate and taxiway flexibility, as it can use the same gates as smaller airplanes. Secondly, raked wingtips offer weight-reduction benefits compared to simply extending the conventional main wingspan. At high load factors, the raked wingtips experience less load and induce less loading on the outboard main wing. Additionally, the leading-edge sweep results in a more favourable centre of pressure location, reducing the bending moment on the inboard wing.
Raked wingtips have been shown to improve fuel efficiency in Boeing aircraft. The 777-300ER, for example, is expected to achieve a 2% fuel efficiency improvement with its raked wingtips, saving up to $140,000 in fuel costs per year per airplane, or 1.3 million pounds of fuel. This also has environmental benefits, reducing carbon dioxide emissions by 3.9 million pounds per year.

The 767-200ER's range is due to extra fuel capacity
The 767-200 was designed to have a sufficient range to fly across North America or the northern Atlantic. The 767-200ER, on the other hand, is an extended-range model that can carry heavier payloads at greater distances. The 767-200ER's increased range is due to its extra fuel capacity and higher maximum takeoff weight (MTOW) of up to 395,000 lb (179,000 kg).
The additional fuel capacity is achieved by using the center tank's dry dock to carry fuel. The non-ER variant's center tank, known as cheek tanks, consists of two interconnected halves in each wing root with a dry dock in between. The center tank is also utilised in the -300ER and -400ER variants.
The 767-200ER was the first 767 to accomplish a non-stop transatlantic journey. On April 17, 1988, an Air Mauritius flight from Halifax, Nova Scotia to Port Louis, Mauritius, broke the flying distance record for a twinjet airliner, covering 8,727 nautical miles (16,200 km; 10,000 mi).
The 767-200ER has been favoured by international operators seeking smaller wide-body aircraft for long-haul routes, such as New York to Beijing. The model's ability to carry heavier payloads over longer distances has made it a popular choice for medium-traffic, long-distance flights.
In addition to the 767-200ER, Boeing has explored other variants with extended range capabilities, such as the 767-400ERX, which was offered in 2000 but later cancelled. The 767-400ERX was designed to have a strengthened wing, fuselage, and landing gear, allowing for a higher MTOW and improved takeoff performance.
