The 400 shares its Petrol V 12 engine configuration with the likes of the 2021 Aston-Martin Valkyrie Spider 6.5 V12 and the 2021 Aston-Martin Valkyrie Coupe 6.5 V12.If you're looking for other similar performing cars which share the 400's Rear Wheel Drive, Coupe combination then how about the 1985 Alfa-Romeo Spider Veloce or the earlier 1982 Fiat X1/9 1.5 8V.

Power and Weight:

Weighing in at 1472 kgs (3245 lbs) places the Lamborghini 400 GT 2+2 3.9L V12 in a similar weight category as the 2025 Maserati MCPURA 3.0 V6 Twin Turbo and the excellent 2025 Ferrari 296 Speciale A, give or take 50kg.

The Lamborghini 400 shares the same bhp with the 2024 Toyota Yaris GR RZ High Performance Automatic (300 bhp)

In terms of pure power the 3929cc 24 valve, V 12 engine produces around 320 bhp (238 kW) @ 6500 rpm which is comparable to the 2024 Toyota Yaris GR RZ High Performance Automatic (300 bhp) and also the 2024 Toyota Yaris GR RC (300 bhp).

The Naturally Aspirated V 12 throws out 262 lb-ft (355.2 Nm) @ 4700 rpm placing it with cars of similar torque performance figures such as the 2024 BYD Sealion 7 Comfort (280 lb-ft) or the 2023 Toyota Corolla GR Circuit Edition 1.6 Turbo (273 lb-ft).

Power to Weight:

If you look at both power or torque of the 1965 Lamborghini 400 in comparison with its weight you get a much more accurate idea of its real world performance.

The 2017 Maserati GranTurismo MC 4.7 V8 (242.3 bhp per ton) has similar Bhp Per Ton stats as the Lamborghini 400.

The Lamborghini 400 has a power to weight ratio of 217.3 bhp per ton. Bhp per ton figures of the 1965 400 GT 2+2 3.9L V12 means you're competing with the 2017 Maserati GranTurismo MC 4.7 V8 (242.3 bhp per ton) and the equally quick 2009 Bentley Continental GTC Speed (242.2 bhp per ton).

Torque to Weight:

If you agree with the late great Carroll Shelby then arguably an even better indicator of potential performance is Torque!. However, torque isn't the whole story, you also need to compare weight as well for more real world comparisons such as torque per ton.

The Lamborghini 400 GT 2+2 3.9L V12 generates around 177.9 lb-ft per ton. So if you're looking at what cars perform similarly either on the drag strip or at the traffic lights using torque to weight as a benchmark, then look no further than the 1993 Mercedes E Class 60 AMG 6.0 V8 W124 (202.9 lb-ft per ton) or the similarly performing 1992 Mercedes SL Class 600SL V12 R129 (202.8 lb-ft per ton).

Acceleration:

The Lamborghini 400 GT 2+2 3.9L V12 can accelerate 0–60mph in 6.60 secs or 0–100km/h (0–62mph) in 6.8 secs. Acceleration rivals to the Lamborghini 400 GT 2+2 3.9L V12 include the 2018 Toyota Sequoia TRD Sport 5.7 V8 (6.60 secs) or the equally as fast to 60mph 2016 Audi A3 2.0 TDI S-tronic Quattro Sportback (6.60 secs).

The V 12 engine of the Lamborghini 400 GT 2+2 3.9L V12 ensures that, ‘on paper’ at least, accelerates slightly faster than the 2020 Ford Puma ST 1.5 Turbo (6.70 secs) and the 2017 Maserati Levante 3.0 V6 Diesel (6.70 secs).

Quarter Mile time is a close race between the Lamborghini 400 GT 2+2 3.9L V12 and the Pontiac GTO 6.6 Litre V8 HO

On a longer format for acceleration comparisons the 1965 Lamborghini 400 can reach a quarter mile in an estimated 13.53 secs with a trap speed around 100.6 mph. Similar performances down the quarter mile drag strip can be found with the the Pontiac GTO 6.6 Litre V8 HO (13.55 seconds @ 100.5 mph) and a close race between the Porsche 928 GTS 5.4L V8 (13.55 seconds @ 100.5 mph) too.

Top Speed:

Some modern performance cars are often artificially restricted particularly when it comes to max speed. 155 mph top speed restrictions are often used as part of the German 'Gentleman's Agreement' for example, so be cautious when using maximum speed figures. The 1965 version of the Lamborghini 400 GT 2+2 3.9L V12 has a maximum speed of 155mph.

Top Speed of the 1965 400 equals the Subaru Impreza WRX STI - Classic 22B (154 mph)

If maxing out your car on the AutoBahn is your thing and you're wondering what has a similar top end performance to the 1965 Lamborghini 400 GT 2+2 3.9L V12 then there's the slightly slower the Subaru Impreza WRX STI - Classic 22B (154 mph) or how about the impressive Audi Q7 4.2 V8 (154 mph).
