Idea: Basically a Concorde with less fuel but offset by having much more efficient engines.

Concorde 200 - from 1994

Seats: 160                 same as the standard Concorde

Speed: 1355 mph      same as the standard Concorde

Range: 7765 mi         ~85% longer range; this number is based on a full 160-seats-filled Concorde

Turn Time: 60 min     same as the standard Concorde

Runway: 8660 ft        lowered by ~8,35% due to reduced weight

Price: $180 Million     ~20% higher price

Lease: $2 Million       ~20% higher monthly lease

Now to the engines:

We will assume a plane for 160 max passengers needs only 2 engines - we're also gonna ignore any mistakes in my "math" shenanigans.

Number of engines: 2

Engine Type: Rolls-Royce Trent 768

Thrust per engine: 67'500 lbs                  significates a total increase of nearly 8%

Weight per engine: 10'550 lbs                 3550 lbs (~50%) more per engine

combined Fuel Flow: 40'500 lbs/hour      equals around 73% less fuel consumption

The Trent engines, straight off the A330, are heavier by themselves but due to the reduced amount of engines, this change saves in total 7100 lbs of weight. In addition to this, the number of fuel tanks will be slightly reduced (the -200 will retain it's feature of additional fuel tanks to control the centre of mass like the original) and the maximum fuel capacity lowered by 50% to a total of 59'750 litres (44'812 lbs for a full cabin).

The much more efficient engines will be able to work flights up to 5:45 h long flights in regular service. This signigicates an additional 2:50 hours of travelling.

a few potential destinations from London Heathrow; transatlantic routes only

Orlando, Mexico City, Miami, Sao Paulo, Fort Lauderdale, Bogotá

all these Airports have demand for at least one daily flight in full economy

R0 may need resetting, it's now in 2024 and the server is supposed to go from 1950 to 2020.
