Rolls-Royce Silver Seraph

Rolls-Royce Silver Seraph: which version to buy

There is one catalogue version of the Rolls-Royce Silver Seraph: 5.4 AT, sold from 1998-01-01 to 2002-12-31 as a Sedan. If you are choosing “which Silver Seraph,” the data here do not split the model into rival engines, gearboxes, or body styles. The buying question is whether 5.4 AT itself matches what you need on power, mass, fuel use, and clearance — not which of several trims to pick.

There is one catalogue version of the Rolls-Royce Silver Seraph: 5.4 AT, sold from 1998-01-01 to 2002-12-31 as a Sedan. If you are choosing “which Silver Seraph,” the data here do not split the model into rival engines, gearboxes, or body styles. The buying question is whether 5.4 AT itself matches what you need on power, mass, fuel use, and clearance — not which of several trims to pick.

Generations: what changed between them

The model has 1 generation. Generation 1 (1998-01-01 to 2002-12-31) is a Sedan with 1 version. There is no second generation in these figures, so there is no later engine, no later gearbox, and no restyle year that adds another row. A buyer cannot “wait for the next generation” inside this catalogue: the only generation is generation 1, and the only version inside it is 5.4 AT.

That single-generation, single-version layout is the whole choice set. Arithmetic below is therefore on 5.4 AT against its own numbers (power per litre, mass per horsepower, tank versus consumption), not against a sibling that is not listed.

Engine and specs: the only row

5.4 AT is Gasoline, 5379 cc, 12 cylinders in a V-shaped layout, 2 valves per cylinder, boost No. The engine sits Front, longitudinal. The fuel system is Distributed injection (multi-point). Compression ratio is 10. Bore and stroke are 85 × 79. Fuel grade is 95. Output is 326 hp (240 kW) at 5000 rpm and 490 Nm at 3900 rpm. The gearbox is Automatic with 5 gears. Drive is RWD.

Power per litre on 5.4 AT is 326 ÷ 5.379 ≈ 60.6 hp per litre. Torque per litre is 490 ÷ 5.379 ≈ 91.1 Nm per litre. Those ratios describe a large-displacement 12-cylinder with boost No: the 5379 cc figure is doing the work, not a listed supercharger or turbo. There is no second engine in the table to raise or lower those ratios.

Performance and mpg

For 5.4 AT, 0–100 is 7.6 s and top speed is 225. Fuel consumption is 25.4 city, 12.8 highway, 17.4 mixed. CO2 is not measured. Eco class is not measured.

City use is 25.4 − 12.8 = 12.6 above the highway figure, and 25.4 − 17.4 = 8.0 above mixed. Mixed is 17.4 − 12.8 = 4.6 above highway. A buyer who mostly drives the city figure is looking at nearly double the highway number (25.4 ÷ 12.8 ≈ 1.98). That is the mpg decision for this model: not a choice between versions, but a choice of how you will use 5.4 AT.

With a 108 tank, mixed range is 108 ÷ 17.4 × 100 ≈ 621 (same units as the consumption figures). City range is 108 ÷ 25.4 × 100 ≈ 425. Highway range is 108 ÷ 12.8 × 100 ≈ 844. The highway–city gap in range is about 844 − 425 = 419. If your use is mixed, the 17.4 figure is the one that belongs next to the 108 tank.

Dimensions, weight, and clearance

Kerb weight for 5.4 AT is 2400. Gross weight is 2795. Ground clearance is 140. Tank is 108. Wheel sizes are not measured. Front suspension is Independent, spring. Rear suspension is Dependent, spring. Front brakes are Ventilated disc. Rear brakes are Disc ventilated.

Payload from the two mass figures is 2795 − 2400 = 395. Mass per horsepower at kerb is 2400 ÷ 326 ≈ 7.36 kg per hp. Mass per horsepower at gross is 2795 ÷ 326 ≈ 8.57 kg per hp. The 0–100 time of 7.6 s sits next to that 2400 kerb figure and 326 hp; there is no lighter version in the data that would cut kg per hp.

Ground clearance is 140. There is no other generation with a different 140 to compare. Wheel sizes are not measured, so tyre choice is not a catalogue differentiator here.

Which version to choose

Choose 5.4 AT if you want the only Silver Seraph version in this catalogue: 326 hp, 490 Nm, 5379 cc Gasoline 12-cylinder V-shaped, boost No, Automatic 5, RWD, 7.6 s to 100, 225 top speed, kerb 2400, clearance 140.

There is no second version name to pick. You cannot trade 326 hp for a smaller engine, or Automatic for another gearbox, or RWD for another drive, because those rows are not in the data. “What the extra money buys” is therefore not a step from a cheaper Silver Seraph to a dearer one: prices are not in the data, and a second version is not in the data either.

What you can decide with the numbers:

• Power versus size. 60.6 hp per litre and boost No mean you are buying displacement (5379 cc) and 12 cylinders, not a boosted smaller engine that is not listed.
• Mass versus power. 7.36 kg per hp at 2400 kerb is the weight you take with 326 hp. Gross 2795 raises that to 8.57 kg per hp; the 395 payload is the difference between those two masses.
• Fuel versus tank. If your use matches 25.4 city, the 108 tank and ~425 city range are the pair. If your use matches 12.8 highway, the same tank stretches to ~844. Mixed 17.4 sits in between at ~621.
• Performance pair. 7.6 s and 225 are one version’s pair; they do not split across trims.
• Chassis pair. Independent, spring at the front and Dependent, spring at the rear, with Ventilated disc / Disc ventilated brakes, and 140 clearance. Wheel sizes are not measured.

If those figures are not what you need — for example if 25.4 city consumption, 2400 kerb, or 140 clearance is the wrong match — this catalogue does not offer another Silver Seraph generation or another named version to switch to. Generation 1, 1998-01-01 to 2002-12-31, Sedan, 5.4 AT, is the full set.

CO2 is not measured. Eco class is not measured. Wheel sizes are not measured. Treat those as unknown, not as zero and not as “the car has no such parameter.”

5.4 AT is the version to buy if the 326 hp / 490 Nm / 5379 cc / Automatic / RWD / 2400 kg / 17.4 mixed set is the car you want. There is no other Silver Seraph version in these data to prefer instead.
