McLaren Senna: which version to buy

The McLaren Senna catalogue lists one generation and one named version: 4.0 DSG. Production of that package starts 2018-01-01 and has no end date in the data. Body type is Coupe. If the question is which Senna to choose from this database, the answer is arithmetic on a single row: 4.0 DSG is the only factory combination of engine, gearbox and drive that is recorded.

The McLaren Senna catalogue lists one generation and one named version: 4.0 DSG. Production of that package starts 2018-01-01 and has no end date in the data. Body type is Coupe. If the question is which Senna to choose from this database, the answer is arithmetic on a single row: 4.0 DSG is the only factory combination of engine, gearbox and drive that is recorded.

There is no second engine, no restyle line, and no later generation to trade against. Extra money cannot buy a second McLaren Senna specification here, because a second specification is not in the table. What you can still choose is how you use the numbers that 4.0 DSG actually has: 800 hp and 800 Nm from 3994 cm³, RWD, Robotic 7, kerb 1314 kg, 2.8 s to 100 km/h, 335 km/h, and mixed fuel use 12.4 L/100 km.

Generations: what changed, and what did not

1 generation is the whole model history in these data. Years: from 2018-01-01, still open (`stop` is empty). Body: Coupe. Count of versions: 1 — 4.0 DSG.

No restyling is listed inside this generation. No second generation exists to compare year ranges, body changes, or version counts. Choosing “an older Senna generation” or “a facelift Senna” is not a choice this catalogue can support: there is only 1 generation, and it contains only 4.0 DSG.

What that generation did lock in is the whole mechanical set of 4.0 DSG: Gasoline 8 V-shaped with Turbo, Central placement, Direct injection (direct), Robotic 7, RWD, Independent, spring suspension front and rear, Ceramic ventilated brakes front and rear, tyres 245/35 R19 and 315/30 R20. None of those fields has a second value to pick instead.

Specs: the only engine and gearbox on the list

4.0 DSG is Gasoline, not a second fuel type. Cylinders are 8, layout is V-shaped, valves per cylinder 4, boost Turbo, placement Central, injection Direct injection (direct). Bore × stroke is 93 × 73.5. Compression ratio is not measured. Fuel grade in the data is 98.

Peak power is 800 hp (588 kW) at 7250 rpm. Peak torque is 800 Nm at 5500 – 6700 rpm. Power and torque share the same headline figure of 800. Specific output from the given displacement:

There is no milder 4.0 DSG and no hotter 4.0 DSG in the same generation. You cannot choose a lower-hp twin with the same name: this catalogue does not list two 4.0 DSG rows at different horsepower.

Gearbox is Robotic with 7 speeds. Drive is RWD. There is no all-wheel-drive Senna version here and no extra ratio count. Choosing 4.0 DSG is choosing rear-wheel drive and a seven-speed Robotic unit together; they are not sold as separate lines in these data.

Euro class is Euro 6. CO₂ is 280. Tank volume is not measured.

Performance, mpg and how the only version uses fuel

4.0 DSG acceleration 0–100 km/h: 2.8 s. Top speed: 335 km/h. Those two figures are the performance set; there is no second version with a slower sprint or a lower peak speed to “save” against.

Kerb-to-power arithmetic on the given mass and power:

Fuel consumption for 4.0 DSG:

City use is 23.6 − 9.8 = 13.8 L/100 km above highway. Mixed sits 12.4 − 9.8 = 2.6 L/100 km above highway and 23.6 − 12.4 = 11.2 L/100 km below city. City is 23.6 / 9.8 ≈ 2.41 times the highway figure.

If the buying question is “which Senna is cheaper to run on fuel,” the catalogue still has only 4.0 DSG. The useful split is duty cycle, not trim:

That is not a second engine. It is the same 4.0 DSG Gasoline Turbo 8 V-shaped unit measured three ways. Tank size is not measured, so range cannot be calculated from these data.

CO₂ 280 and class Euro 6 are the emissions pair for this sole version. There is no cleaner Senna row to pick.

Dimensions, weight and wheels: what you cannot trade off

Kerb weight of 4.0 DSG: 1314 kg. Gross vehicle weight: not measured. Ground clearance: not measured. Fuel tank: not measured.

Wheels for 4.0 DSG: 245/35 R19 and 315/30 R20. The rear listed size is 70 mm wider than the front (315 − 245) and one inch larger in rim diameter (R20 vs R19). There is no alternative wheel line in the data.

Suspension: Independent, spring front, Independent, spring rear. Brakes: Ceramic ventilated front, Ceramic ventilated rear. No steel-brake version and no different rear-axle layout are listed, so you cannot buy a “softer” Senna by changing those fields in this catalogue.

Because gross mass is not measured, payload is not measured. Because clearance is not measured, this article does not invent a figure.

Which version to choose

Choose 4.0 DSG. It is the only named version. The generation is 1 generation, body Coupe, years from 2018-01-01 with no recorded stop.

What 4.0 DSG buys, in the numbers given:

What extra money does not buy in this database: a second generation, a restyle, a second 4.0 DSG with different horsepower, a different gearbox type, a different drive type, a different body, or a measured tank, clearance, gross weight, or compression ratio. Those fields are either unique to 4.0 DSG or not measured.

Reliability, common problems, and prices are not in the launch data, so they are not used to rank versions. The ranking that the numbers support is a ranking of one: 4.0 DSG in 1 generation, Coupe, from 2018-01-01.
