Lexus RC F

Lexus RC F: which 5.0 AT to buy — specs compared

If you are choosing a Lexus RC F, every listed car is a Coupe 5.0 AT: a 4969 cm³ Gasoline V-shaped 8-cylinder, 4 valves per cylinder, no boost, front longitudinal, direct injection (direct), 8-speed Automatic, RWD. The useful split is not the name — it is horsepower, kerb weight, 0–100, mixed consumption, and whether the car is 1 generation (2014–2018) or 1 generation, restyling (from 2019).

If you are choosing a Lexus RC F, every listed car is a Coupe 5.0 AT: a 4969 cm³ Gasoline V-shaped 8-cylinder, 4 valves per cylinder, no boost, front longitudinal, direct injection (direct), 8-speed Automatic, RWD. The useful split is not the name — it is horsepower, kerb weight, 0–100, mixed consumption, and whether the car is 1 generation (2014–2018) or 1 generation, restyling (from 2019). Six versions exist. Three share the label 5.0 AT in each period; they are told apart only by output: 464 hp, 474 hp, and either 477 hp (1 generation) or 481 hp (restyling).

Lexus RC F generations: what actually changed

1 generation (2014-01-01 to 2018-12-31), Coupe, 3 versions. All 5.0 AT. The lightest is 5.0 AT 477 hp at 1765 kg; the heaviest is 5.0 AT 464 hp at 1840 kg — 75 kg more for 13 hp less. Mixed consumption is lowest on 5.0 AT 477 hp at 10.8 l/100 km and highest on 5.0 AT 474 hp at 12.4. Measured 0–100 is 4.5 s on 464 hp and 477 hp, 4.6 s on 474 hp. Top speed is 270 km/h on 464 hp and 477 hp, 273 km/h on 474 hp.

1 generation, restyling (from 2019-01-01, stop not measured), Coupe, 3 versions. Same body type, same 5.0 AT name, same 4969 cm³, same 8 / V-shaped / No boost layout. Power steps become 464, 474, 481 hp. The restyling 5.0 AT 464 hp drops kerb weight from 1840 kg to 1715 kg (−125 kg) with the same 464 hp, 4.5 s, and 270 km/h. The 5.0 AT 474 hp keeps 1795 kg in both periods but 0–100 improves from 4.6 s to 4.4 s (−0.2 s) and top speed moves from 273 to 272 km/h. The top restyling step is 5.0 AT 481 hp; 0–100 and top speed for that version are not measured.

Catalogue count of generation records is 2; both records are the first generation, one of them the restyling. There is no second numbered generation in the names.

Lexus RC F engine specs: all 5.0 AT versions

Displacement is 4969 cm³ on every row. Compression is 12.3. Bore × stroke is 94 × 89.5. Peak power is at 7100 rpm on every version. Gearbox is Automatic, 8, RWD.

Specific output from 4969 cm³: 464 hp → 93.4 hp/l, 474 hp → 95.4 hp/l, 477 hp → 96.0 hp/l, 481 hp → 96.8 hp/l. Torque steps on the restyling are +7 Nm from 464 to 474 hp and +8 Nm from 474 to 481 hp (520 → 527 → 535). On 1 generation the top step is 477 hp / 530 Nm, not 481.

Fuel grade is 95 on five versions. Only restyling 5.0 AT 481 hp is specified for 98. That is the only fuel difference in the table.

Horsepower, torque, and 0–100: what the extra output buys

On the restyling, 474 hp versus 464 hp is +10 hp (+2.2%) and +7 Nm. 0–100 is 4.4 s versus 4.5 s (−0.1 s). Top speed is 272 versus 270 (+2 km/h). You also pick up 80 kg of kerb weight (1795 vs 1715). Mass per horsepower is 3.79 kg/hp on 474 hp versus 3.70 kg/hp on 464 hp — the extra 10 hp does not offset the extra 80 kg.

481 hp versus 464 hp (restyling) is +17 hp (+3.7%) and +15 Nm. Kerb weight is 1770 kg, 55 kg more than the 464 hp restyling car, 25 kg less than the 474 hp restyling car. Mass per horsepower is 3.68 kg/hp — the lowest of the six. 0–100 and top speed are not measured, so the 17 hp gap cannot be cashed as a proven sprint or speed figure.

481 hp versus 474 hp (restyling) is +7 hp and +8 Nm, −25 kg. Mixed consumption is 11.8 versus 12.4 l/100 km (−0.6). City use is worse: 18.9 versus 14.7 (+4.2 l/100 km). Highway is 9.1 versus 9.4 (−0.3).

On 1 generation, 477 hp versus 464 hp is +13 hp and +10 Nm with 75 kg less kerb weight (1765 vs 1840). Mass per horsepower: 3.70 kg/hp versus 3.97 kg/hp. 0–100 is the same 4.5 s; top speed is the same 270 km/h. Mixed use is 10.8 versus 11.3 (−0.5 l/100 km). The 477 hp car is the one that actually improves both mass and economy versus the 464 hp car in that period.

474 hp versus 464 hp on 1 generation is +10 hp, +7 Nm, 45 kg less (1795 vs 1840), but 0–100 is slower: 4.6 s versus 4.5 s. Top speed is the catalogue peak at 273 km/h (+3 vs 464/477). Mixed consumption is the worst of that generation at 12.4 l/100 km.

474 hp, restyling versus 1 generation: same 474 hp, 351 kW, 527 Nm, 1795 kg. Sprint 4.4 s instead of 4.6 s; top speed 272 instead of 273. City/highway/mixed figures are identical (14.7 / 9.4 / 12.4). The restyling 474 hp car is the same mass with a 0.2 s quicker 0–100 and 1 km/h less peak speed.

464 hp, restyling versus 1 generation: same 464 hp, 341 kW, 520 Nm, same 4.5 s and 270 km/h. Kerb weight 1715 vs 1840 (−125 kg, −6.8%). Mixed 11.8 vs 11.3 (+0.5). CO2 268 vs 258 g/km. Euro 6 on both. The restyling 464 hp car is the lightest RC F in the data (1715 kg) and the strongest kg/hp among the two 464 hp rows (3.70 vs 3.97).

Restyling 481 hp versus 1 generation 477 hp: +4 hp, +5 Nm, +5 kg (1770 vs 1765). Fuel 98 versus 95. Mixed 11.8 versus 10.8 (+1.0). City 18.9 versus 16.1 (+2.8). Highway 9.1 versus 7.8 (+1.3). 0–100 and top speed: not measured on 481 hp versus 4.5 s / 270 km/h on 477 hp. If you need a measured sprint, 477 hp has the number; 481 hp does not.

Lexus RC F mpg / fuel use and Euro 6

Tank is 66 litres on every version. CO2 and eco class are measured only where stated.

Which Lexus RC F version to choose

Buy restyling 5.0 AT (464 hp) if the number you care about is mass. It is the lightest RC F here (1715 kg), 125 kg below the 2014–2018 5.0 AT 464 hp, with the same 464 hp, 4.5 s, 270 km/h, 95 fuel, Euro 6. You give up 0.5 l/100 km mixed versus the older 464 hp car (11.8 vs 11.3) and 10 hp versus the restyling 474 hp car, but you avoid the 80 kg the 474 hp restyling car adds.

Buy restyling 5.0 AT (474 hp) if the number you care about is a measured 0–100. 4.4 s is the shortest sprint in the data. Versus restyling 464 hp that is −0.1 s for +10 hp and +80 kg. Versus the 2014–2018 5.0 AT 474 hp it is the same 1795 kg and the same 12.4 mixed, with −0.2 s and −1 km/h. City 14.7 is the best city figure; mixed 12.4 is the worst mixed figure. CO2 and Euro class are not measured.

Buy restyling 5.0 AT (481 hp) only if you want the peak hp/Nm and accept 98 fuel plus missing sprint/speed. 481 hp / 354 kW / 535 Nm is the catalogue ceiling. Specific output 96.8 hp/l and 3.68 kg/hp are the best ratios. 0–100 and top speed are not measured. City 18.9 is the worst city figure; mixed matches restyling 464 hp at 11.8.

Buy 1 generation 5.0 AT (477 hp) if you want the strongest pre-restyling package with full measured economy and Euro 6. 477 hp, 530 Nm, 1765 kg, 4.5 s, 270 km/h, mixed 10.8, highway 7.8, CO2 252 — best mixed, best highway, lowest stated CO2. Versus restyling 481 hp you lose 4 hp and 5 Nm, gain a measured 4.5 s / 270 km/h, use 95 instead of 98, and use 1.0 l/100 km less mixed.

Buy 1 generation 5.0 AT (474 hp) if the number you care about is top speed. 273 km/h is the highest measured peak. 0–100 is the slowest measured at 4.6 s. Same 1795 kg and 12.4 mixed as the restyling 474 hp car.

Buy 1 generation 5.0 AT (464 hp) only if that is the car in front of you and the restyling 464 hp is not. Same power, same 4.5 s, same 270 km/h, Euro 6, better mixed than the restyling 464 (11.3 vs 11.8), but 1840 kg — heaviest RC F, 3.97 kg/hp, 410 kg to gross. The restyling 464 hp car is the same output 125 kg lighter.
