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 Koenigsegg Agera RS 5.1 V8 Twin Turbo generates around 676.7 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 2015 Koenigsegg Agera RS 5.1 V8 Twin Turbo (676.7 lb-ft per ton) or the similarly performing 2006 Caparo T1 2.4 V8 (661.7 lb-ft per ton).

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 2015 version of the Koenigsegg Agera RS 5.1 V8 Twin Turbo has a maximum speed of 250mph.

Top Speed of the 2015 Agera equals the SSC Aero SC 8T 6.3L (249 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 2015 Koenigsegg Agera RS 5.1 V8 Twin Turbo then there's the slightly slower the SSC Aero SC 8T 6.3L (249 mph) or how about the impressive Koenigsegg Gemera 2.0 Turbo Petrol Hybrid (249 mph).
