Fuel burn rate: 27.1–32 gallons/hour
The fuel burn rate of the Baron G58 depends on various factors, such as the power setting, load, and altitude. According to pilots, the G58 Baron burns around 27.1 to 32 gallons per hour. This burn rate can be affected by how the plane is being flown. For example, flying at 195 knots will burn 34 gallons per hour, while reducing the speed to 185 knots will reduce fuel burn to 32 gallons per hour.
The G58 has a fuel capacity of 194 gallons, which gives it a range of 915 to 1,332 nautical miles, depending on the power setting, load, and altitude. At a burn rate of 16 to 17 gallons per engine per hour, the G58 can endure for five hours with a range of 1,000 nautical miles. This range can be increased to 1,300 nautical miles with long-range power settings at 10,000 feet.
The G58's fuel efficiency is a trade-off for its powerful performance. With a climb rate of 1,800 feet per minute near sea level and a maximum gross weight of 5,500 pounds, the G58 offers excellent climb capabilities and can reach cruise altitude in just five to seven minutes.
The G58's fuel burn rate is a consideration when planning flights, especially when carrying a full load of passengers and luggage. To accommodate six full-size passengers and reasonable luggage, the fuel load may need to be limited to around 58 gallons, providing around one and a quarter hours of flight time plus reserve.
The G58's fuel efficiency also impacts its operating costs. With a fuel cost of $6 per gallon and an average fuel burn of 30 gallons per hour (assuming a burn rate of 27.1 to 32 gallons per hour), the variable costs associated with fuel can be estimated at around $(6 x 30) = $180 per hour. This contributes to the G58's overall annual budget, which can be upwards of $190,000.

Cruise speed: 185–200 knots
The Baron G58 is a powerful aircraft with impressive performance capabilities. At a cruise speed of 185-200 knots, the fuel consumption and range of the G58 are notable aspects to consider.
Firstly, it's important to understand that fuel consumption can vary based on various factors, including power settings, load, and altitude. With that in mind, let's delve into the fuel burn of the G58 at cruise speeds of 185-200 knots:
At 185 knots, the G58 burns approximately 35 gallons per hour in total. This is achieved by indicating about 800 feet per minute in the climb with engine power at 23 inches of manifold pressure and props holding 2,500 rpm.
Now, at the higher end of the cruise speed range, the G58 burns slightly more fuel. At 200 knots, the aircraft consumes around 32 gallons per hour. This is measured at 11,000 feet with 20.3 inches of manifold pressure and 2,500 rpm. It's worth noting that by running lean of peak, the fuel burn can be reduced to 26 gallons per hour, although this will result in a slight decrease in speed to 194 knots.
The G58's fuel efficiency contributes to its impressive range capabilities. With a maximum fuel capacity of 194 gallons, the aircraft can cover a range of 915 nautical miles to 1,332 nautical miles, depending on the power settings, load, and altitude. Additionally, with four people on board and cruising at maximum speed, the G58 can cover just over 800 nautical miles with reserves, while economy cruise can extend this range to nearly 1,500 nautical miles.
In summary, the Baron G58's fuel consumption at cruise speeds of 185-200 knots falls within the range of 26 to 35 gallons per hour, depending on specific conditions and power settings. This fuel efficiency allows the G58 to offer a considerable range, making it a capable and versatile aircraft in its class.

Fuel capacity: 194 gallons
The Beechcraft G58 Baron has a fuel capacity of 194 gallons. This top-of-the-line luxury light twin aircraft was introduced in 2005 or 2006 and is the only Baron still in production today. It is priced at around $1.1 million for a new model and $1 million for a pre-owned aircraft.
The G58 Baron's fuel capacity gives the airplane a range of 915 to 1,332 nautical miles, depending on factors such as power settings, load, and altitude. The aircraft's fuel burn rate is around 26 to 32 gallons per hour, and it has an average cruise speed of about 185 to 200 knots.
The G58 Baron's fuel efficiency can be improved by adjusting the power settings. For example, running lean of peak can reduce fuel consumption to 26 gallons per hour, while dialing the power back to 2,100 rpm can result in a more efficient speed of 170 knots.
The G58 Baron's fuel capacity and range are important considerations for pilots, especially when planning longer flights or carrying heavier loads. The aircraft's range can be extended by utilizing long-range power settings at higher altitudes, such as 10,000 feet, which can increase the range to 1,300 nautical miles or more.
The G58 Baron's fuel capacity and performance characteristics contribute to its overall capabilities and operational flexibility. With its powerful engines, spacious cabin, and advanced avionics, the G58 Baron is a versatile and high-performance aircraft, well-suited for various missions and catering to different user needs.

Range: 915–1,332 nautical miles
The Beechcraft G58 Baron has a fuel capacity of 194 gallons, which gives the aircraft a range of 915–1,332 nautical miles. This range depends on several factors, including power settings, load, and altitude.
The G58 Baron's fuel consumption rate falls between 26 and 34 gallons per hour. This rate can be affected by various factors, such as the power settings and the number of passengers and luggage on board.
For example, if the aircraft is flown at 200 knots true airspeed at 20.3 inches and 2,500 rpm, the fuel burn is 32 gallons per hour. However, if the power is reduced to 2,100 rpm, the speed decreases to 170 knots, and the fuel consumption drops to approximately 26 gallons per hour.
The number of passengers and luggage can also significantly impact fuel efficiency. According to pilots, to carry six full-size passengers with reasonable luggage, the fuel load would need to be limited to around 58 gallons, providing about one and a quarter hours of flight time plus reserve.
Additionally, the G58 Baron's range can be influenced by the cruise speed. At a speed of 195 knots and a fuel burn of 34 gallons per hour, the range would be impacted. However, reducing the speed to 185 knots and decreasing the fuel burn by 2 gallons per hour would result in a more efficient cruise.
The G58 Baron's range of 915–1,332 nautical miles offers flexibility in terms of fuel planning and endurance, depending on the specific flight requirements and conditions.
