Koenigsegg Regera: Which Version to Choose and Why
The Koenigsegg Regera catalogue data presents one clear choice: the 5.0 AT. There is only one generation, one Targa body type, and one listed version, so buyers cannot compare alternative engines, gearboxes, drivetrains, or generations within this model.
The Koenigsegg Regera catalogue data presents one clear choice: the 5.0 AT. There is only one generation, one Targa body type, and one listed version, so buyers cannot compare alternative engines, gearboxes, drivetrains, or generations within this model. The decision instead comes down to whether the specifications of the 5.0 AT suit the intended use: 1100 hp, 1280 Nm, a 5065 cm³ Hybrid powertrain, Automatic transmission, RWD, and acceleration from 0 to 100 km/h in 2.8 seconds.
Koenigsegg Regera generations: what can be compared?
The Regera has 1 generation, which started on 2015-03-01 and has no recorded end date. This generation uses a Targa body and contains 1 version, the 5.0 AT.
Because the supplied catalogue includes no earlier or later Regera generation, there is no generation-to-generation change in power, body style, performance, weight, or drivetrain to calculate. Restyling information is also not provided. For a buyer, this means that the generation is not the deciding factor: the available comparison is between the 5.0 AT’s measurable strengths and the specifications that remain not measured.
Koenigsegg Regera engine and specs
| Version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 5.0 AT | 1100 hp (820 kW) at 7800 rpm | 1280 Nm at 4100 rpm | 5065 cm³ | 98 | 8 | V-shaped | Turbo | Automatic | RWD |
The 5.0 AT uses a Hybrid powertrain with 8 cylinders in a V-shaped layout. It has 4 valves per cylinder, Turbo boost, Central engine placement, and Direct injection (direct). Its compression ratio is 9.3, while the cylinder bore and piston stroke are 92 × 95.3.
Calculated from the supplied displacement and output, the 5.0 AT produces approximately 217.2 hp per litre. Its specific torque is approximately 252.7 Nm per litre. Those figures do not compare one Regera version with another—there is no second version in the data—but they describe how much output the listed powertrain develops relative to its displacement.
The relationship between peak-output speeds is also explicit: maximum power arrives at 7800 rpm, while maximum torque arrives at 4100 rpm, a difference of 3700 rpm. This is useful when assessing the specification, although the data does not provide driving-mode or gear-ratio information.
Koenigsegg Regera performance and economy
The 5.0 AT accelerates from 0 to 100 km/h in 2.8 seconds. Top speed is not measured in the supplied data.
City fuel consumption is not measured, highway fuel consumption is not measured, and combined fuel consumption is not measured. CO₂ emissions are not measured, and the environmental class is not measured. Consequently, the catalogue data supports a performance comparison based on acceleration, power, torque, and weight, but it does not support an mpg or emissions comparison.
With a kerb weight of 1628 kg and output of 1100 hp, the calculated power-to-weight ratio is approximately 675.7 hp per tonne. The inverse figure is approximately 1.48 kg per hp. Using the stated 820 kW, the car provides approximately 503.7 kW per tonne.
These calculations help explain why the 5.0 AT is the performance-focused choice in the range, but they cannot establish that it is faster than another Regera version because no alternative version is listed.
Koenigsegg Regera dimensions, weight, tank, and wheels
The 5.0 AT has a kerb weight of 1628 kg. Gross weight is not measured. Ground clearance is 85 mm, and fuel-tank capacity is 82 litres.
The listed wheel sizes are 275/35 R19 and 345/30 R20. The front suspension is Independent, pneumatic, and the rear suspension is also Independent, pneumatic. Both front and rear brakes are Ceramic ventilated.
The difference between the listed rim diameters is 1 inch, while the listed tyre widths differ by 70 mm. These are direct arithmetic comparisons of the catalogue wheel specifications; the supplied data does not state any alternative wheel package.
Overall length, width, height, and wheelbase are not measured in the provided data. Accordingly, the 5.0 AT can be assessed here by weight, clearance, tank capacity, and wheel sizes, but not by its exterior dimensions.
Which Koenigsegg Regera version should you buy?
Choose the 5.0 AT if the required Regera specification is a 1100 hp, 1280 Nm Hybrid with Automatic transmission, RWD, and a 2.8-second 0–100 km/h figure. It is not merely the highest-output or quickest listed Regera; it is the only listed Regera version, so there is no lower-powered, lighter, more economical, or differently driven alternative in this catalogue.
There is also no measurable “extra money” comparison. Price data is not provided, and a second version against which to calculate a premium does not exist in the supplied range. Likewise, no claim can be made about which version offers better fuel economy, because city, highway, and combined consumption are all not measured.
The meaningful trade-off is therefore between known and unknown specifications. The known case for the 5.0 AT is strong numerical performance: 1100 hp, 1280 Nm, approximately 217.2 hp per litre, approximately 675.7 hp per tonne, and 0–100 km/h in 2.8 seconds. The unknown side includes top speed, fuel consumption, CO₂ emissions, gross weight, and overall exterior dimensions, all of which are not measured.
For buyers choosing strictly from the supplied Regera catalogue, the recommendation is straightforward: select the 5.0 AT if those documented performance and drivetrain specifications meet the brief. Anyone whose decision depends on mpg, top speed, emissions, gross weight, or full exterior dimensions should not infer those values from the available figures, because the catalogue does not measure them.
