Learjet 45XR: Complete Specs, Performance, and Buyer's Guide (2026)

The Bombardier Learjet 45XR, produced from 2003-2004 to 2012, is the performance-upgraded variant of the Learjet 45, designed to address hot-and-high operating limitations of the original 45. Powered by twin Honeywell TFE731-20BR turbofan engines producing 3,500 lbf each (same thrust as the 45's -20AR engines, but with higher Interstage Turbine Temperature ratings), the 45XR delivers improved hot-and-high performance, reduced balanced field length, increased payload-to-range capability, and 1,685 nautical miles seats-full range with NBAA IFR reserves. Maximum cruise reaches 464 ktas (Mach 0.81), service ceiling is 51,000 ft, typically operated with two pilots. The 45XR includes the Honeywell RE-100 Auxiliary Power Unit as standard (optional on the predecessor 45). A total of 208 Learjet 45XRs were built before production ended in 2012. Pre-owned market today: average $4.2 million.

For operators wanting Learjet 45 platform with improved hot-and-high performance and standard APU, the 45XR is the natural choice.

History as the Performance-Upgraded Lear 45

The Learjet 45XR was introduced in 2003-2004 as a performance improvement program addressing limitations found in some areas of the original Learjet 45. The key upgrade was the new TFE731-20BR engine variant with higher ITT (Interstage Turbine Temperature) ratings.

Platform timeline:

  1. 1998: Original Learjet 45 enters service
  2. 2003: Learjet 45XR launched
  3. 2004: 45XR full service entry (June 2004)
  4. 2006: Original Learjet 45 production ends, 45XR continues
  5. 2012: Learjet 45XR production ends (208 total built)
  6. 2013: Replaced by Learjet 75 (further modernized)

The 45XR continued through the late Learjet era, with the related Learjet 40 and 40XR variants forming Bombardier's complete Learjet product offering until the Learjet 70/75 introduction.

Key Improvements: 45XR vs Lear 45

The Learjet 45XR introduced several focused performance enhancements:

1. Honeywell TFE731-20BR Engines

The major improvement over the predecessor 45:

  • Same 3,500 lbf thrust per engine: As the -20AR
  • Higher Interstage Turbine Temperature ratings: Key technical change
  • Wider temperature and density altitude operating envelope: Maintains thrust in hot/high conditions
  • Reduced balanced field length: Better short-field capability
  • Better payload-to-range: More flexibility
  • Faster cruise speeds: Improved performance
  • Faster time-to-climb: Better departure efficiency

2. Standard Honeywell RE-100 APU

The Honeywell RE-100 APU became standard equipment on the 45XR (it was optional from the factory on the original 45). Benefits:

  • Ground operations independence: Heat/cool cabin without engine starts
  • Pre-flight passenger comfort: APU runs while passengers board
  • Reduced engine cycles: Engines started just before taxi
  • Standard equipment: No optional cost

3. Refined Cabin

Newly-built 45XR units included subtle cabin improvements:

  • Slightly rearranged cabin floor: Better space utilization
  • More comfortable seats: Updated executive seating
  • Improved lighting: Refined ambiance
  • More legroom for passengers: Comfort improvement

Cabin Interior

The 45XR cabin retains the proven Learjet 45 dimensions:

Cabin MeasurementValue
Cabin Length19 ft 9 in
Cabin Width5.08 ft (61 inches)
Cabin Height4.92 ft (59 inches)
Cabin Volume410 cubic ft

Seating Configurations

The 45XR's balanced field length improvements over the original 45 come from the upgraded engine's better thrust retention in hot/high conditions.

Typical Mission Examples

  • New York to Dallas (1,373 nm)
  • Los Angeles to Chicago (1,512 nm)
  • Houston to Boston (1,531 nm)
  • London to Athens (1,481 nm)

Engines

Two Honeywell TFE731-20BR turbofan engines, each producing 3,500 lbf of thrust (9,200 lbf total). The "BR" variant features:

  • Higher ITT (Interstage Turbine Temperature) ratings: Key technical change vs -20AR
  • Wider operating envelope: Better hot/high performance
  • Same baseline thrust as Lear 45: 3,500 lbf
  • Improved fuel consumption: Subtle efficiency gain
  • Standard thrust reversers: Operational flexibility

Avionics

Honeywell Primus 1000 integrated avionics suite (same as Lear 45):

  • EFIS displays: Modern glass cockpit
  • Flight management system: Integrated FMS
  • Weather radar: Standard
  • TCAS: Standard
  • TAWS: Standard
  • Common retrofits: ADS-B Out, WAAS/LPV upgrades

Operating Costs

2008 to 2009 Learjet 45XR$4,450,000 to $4,800,000
2004 to 2007 Learjet 45XR (early production)$3,500,000 to $4,200,000

Per AircraftBluebook: $4.45 to $5.25 million for 2008-2012 production years. Pre-owned average across all years: $4.2 million.

Mission Profile

Best fit profiles:

  1. Step-Up From Learjet 45: Improved hot-and-high performance, standard APU
  2. Hot-and-High Operators: Critical use case for 45XR vs standard 45
  3. 8-Passenger Corporate Flight Departments: Double-club + standard APU
  4. Charter Operators: Modern Learjet at attainable cost
  5. High-Altitude/Hot-Climate Bases: Denver, Phoenix, mountain destinations

Less suited if:

  • You need single-pilot certification (consider CJ family)
  • You require modern Garmin G5000 touchscreen avionics
  • You need transcontinental range (1,685 nm seats-full modest)
  • You want Garmin Bombardier Vision flight deck (consider Lear 75)

Pros and Cons

What the Learjet 45XR Does Well

  • TFE731-20BR engines with higher ITT (better hot-and-high)
  • Standard Honeywell RE-100 APU
  • 410 cu ft double-club cabin
  • 51,000 ft service ceiling
  • 464 ktas (Mach 0.81) cruise
  • Refined cabin vs Lear 45
  • Reduced balanced field length vs Lear 45
  • 203-aircraft active fleet (strong support)
  • 50 cu ft external baggage

Tradeoffs to Understand

  • Two-pilot operation required
  • 1,643-1,685 nm seats-full range modest
  • Avionics dated vs current Garmin G5000
  • Bombardier factory support historically inconsistent
  • Production ended 2012 (parts supply through Textron Aviation)
  • Same baseline thrust as Lear 45 (improvements are in operating envelope)

Frequently Asked Questions

How is the Learjet 45XR different from the Learjet 45?

The 45XR (2003-2004) introduced the Honeywell TFE731-20BR engines (replacing -20AR) with higher Interstage Turbine Temperature ratings, delivering improvements in hot-and-high performance, reduced balanced field length, and increased payload-to-range. The Honeywell RE-100 APU became standard (was optional on the original 45). Cabin had minor refinements with improved seating, lighting, and legroom.

How many Learjet 45XRs were built?

A total of 208 Learjet 45XR aircraft were built during the 2003 to 2012 production run, with 203 active and 4 retired as of recent counts.

Is the Learjet 45XR single-pilot certified?

No. The Learjet 45XR requires two pilots.

How far can a Learjet 45XR fly?

The Learjet 45XR has a maximum NBAA IFR range of 1,643 to 1,685 nautical miles with seats full.

What is the Honeywell RE-100 APU?

The Honeywell RE-100 is the standard Auxiliary Power Unit on the Learjet 45XR, providing electrical power and pneumatic source for cabin heating/cooling on the ground without requiring engine starts. It enables passenger boarding with full cabin conditioning and pre-flight engine preparation.

What is the difference between Learjet 45XR and Learjet 75?

The Learjet 75 (2013) is the major successor to the 45XR, introducing the Garmin G5000-based Bombardier Vision avionics suite (replacing Primus 1000), upgraded Honeywell TFE731-40BR engines (3,850 lbf vs 45XR's 3,500 lbf), redesigned canted winglets, and refined cabin systems. The 75 has 2,040 nm range vs 45XR's 1,685 nm.

The Bottom Line

The Bombardier Learjet 45XR is the proven performance-upgraded variant of the Learjet 45 platform, delivering improved hot-and-high capability through TFE731-20BR engines, standard Honeywell RE-100 APU, and refined cabin. With 208 aircraft built and 203 active in fleet, the platform is well-supported. At current pre-owned pricing averaging $4.2 million, the 45XR delivers modern Learjet capability with the practical advantage of standard APU and improved hot-and-high performance. For operators based in hot or high-altitude markets, the 45XR is meaningfully better than the standard 45.
