Cadillac XTS generations compared: 2012–2017 versus the 2017 restyling
The first generation ran from 2012-01-01 to 2017-10-31 as a Sedan with 4 versions. The restyling (listed as 1 generation, restyling 1) ran from 2017-11-01 to 2019-10-31 as the same Sedan with 3 versions. That is not a second generation: it is the same generation with a shorter, tighter line-up.
The first generation ran from 2012-01-01 to 2017-10-31 as a Sedan with 4 versions. The restyling (listed as 1 generation, restyling 1) ran from 2017-11-01 to 2019-10-31 as the same Sedan with 3 versions. That is not a second generation: it is the same generation with a shorter, tighter line-up.
What the restyling changed, by arithmetic on the listed figures:
- Naturally aspirated peak output fell from 325 hp (239 kW) to 309 hp (227 kW): 16 hp and 12 kW less, and torque from 371 Nm to 358 Nm (13 Nm less).
- Turbo peak output rose from 410 hp to 416 hp: 6 hp more. Kilowatt figures are not a clean step-up: first-generation turbo 3.6 AT is 306 kW (FWD) or 302 kW (AWD); restyled 3.6 V6 T AWD AT is 305 kW.
- Specified fuel dropped from 95 to 92 on every restyled version.
- Compression ratio on the non-turbo engines moved from 11.4 to 11.5; turbo compression stayed at 10.2.
- Restyling versions carry unique names (3.6 V6 AT, 3.6 V6 AWD AT, 3.6 V6 T AWD AT). First-generation versions share the name 3.6 AT and must be told apart by horsepower and drive.
If you want a 2013, 2014, 2016 or 2017 Cadillac XTS, you are in the first-generation window. A 2019 Cadillac XTS is restyling only. Calendar 2017 straddles both: stop of the first cycle is 2017-10-31, start of restyling is 2017-11-01.
Cadillac XTS engine options: specs table
| Version | hp (kW @ rpm) | Nm @ rpm | cm³ | Fuel | Cyl. / layout | Boost | Gearbox | Drive |

Cadillac XTS engine size is 3564 cm³ on every row. Cadillac XTS horsepower is not one number: 309, 325, 410 or 416 hp. Specific output from those figures: 325 hp ÷ 3.564 L = 91.2 hp/L; 309 hp = 86.7 hp/L; 410 hp = 115.0 hp/L; 416 hp = 116.7 hp/L. The restyling non-turbo engines are the least dense; 3.6 V6 T AWD AT is the densest.
Bore × stroke is 94 × 85.6 mm wherever it is measured (all four first-generation 3.6 AT except the 410 hp AWD, where it is not measured; all three restyling versions). Engine position is Front, longitudinal only on the 410 hp FWD 3.6 AT; on the other six versions it is not measured.
Performance and economy: 0–100, top speed, mpg-style consumption
Measured 0–100 km/h exists only in the first generation:
- 3.6 AT 325 hp FWD: 6.7 s
- 3.6 AT 325 hp AWD: 6.9 s (0.2 s slower than the FWD twin)
- 3.6 AT 410 hp FWD: 5.7 s
- 3.6 AT 410 hp AWD: 5.7 s (same sprint as the FWD turbo)
AWD on the 325 hp pair costs 0.2 s. AWD on the 410 hp pair costs nothing in the recorded sprint. Turbo versus non-turbo on the same generation is 1.0 s (FWD: 6.7 vs 5.7) or 1.2 s (AWD: 6.9 vs 5.7).
Top speed is 250 km/h on first-generation 3.6 AT 325 hp FWD, 325 hp AWD, and 410 hp AWD. On 410 hp FWD 3.6 AT top speed is not measured. On all three restyling versions both 0–100 and top speed are not measured.
City / highway / mixed L/100 km:
- 3.6 AT 325 hp AWD: 13.8 / 8.7 / 11.1
- 3.6 AT 410 hp FWD: not measured / not measured / not measured
- 3.6 AT 410 hp AWD: 14.7 / 9.8 / 12.4
- 3.6 AT 325 hp FWD: 13.8 / 8.4 / 11.1
- 3.6 V6 AT: 12.3 / 8.4 / mixed not measured
- 3.6 V6 AWD AT: 13.8 / 9.0 / mixed not measured
- 3.6 V6 T AWD AT: 14.7 / 10.2 / mixed not measured
What the extra hardware costs in fuel, where both sides are measured: restyling FWD non-turbo 3.6 V6 AT uses 1.5 L/100 km less in the city than first-generation 325 hp FWD 3.6 AT (12.3 vs 13.8) and the same 8.4 on the highway. Restyling AWD non-turbo matches the first-generation AWD city figure (13.8) and uses 0.3 L/100 km more on the highway (9.0 vs 8.7). Turbo AWD city is 14.7 in both generations; highway is 0.4 L/100 km higher after restyling (10.2 vs 9.8). Mixed figures exist only for three first-generation versions; they are not measured after restyling.
Cadillac XTS weight, ground clearance, tank, wheels
Kerb weight and kg per horsepower (kerb ÷ hp):
| Version | Kerb, kg | kg/hp | Clearance, mm | Tank, L | Wheels |
|---|---|---|---|---|---|
| 3.6 AT 325 hp AWD | 1896 | 5.83 | 130 | 70 | not measured |
| 3.6 AT 410 hp FWD | 1877 | 4.58 | 155 | 70 | 245/45 R19, 245/40 R20 |
| 3.6 AT 410 hp AWD | 1896 | 4.62 | 130 | 70 | not measured |
| 3.6 AT 325 hp FWD | 1812 | 5.58 | 130 | 70 | not measured |
| 3.6 V6 AT | 1824 | 5.90 | not measured | 70 | not measured |
| 3.6 V6 AWD AT | 1824 | 5.90 | not measured | 70 | not measured |
| 3.6 V6 T AWD AT | 1990 | 4.78 | not measured | 70 | not measured |
Gross weight is not measured on any Cadillac XTS version in these data. The tank is 70 L on all seven.
Lightest car: 325 hp FWD 3.6 AT at 1812 kg. Heaviest: restyled 3.6 V6 T AWD AT at 1990 kg (178 kg more than that FWD non-turbo, 94 kg more than first-generation 410 hp AWD 3.6 AT). Restyling put the same 1824 kg on both FWD and AWD 309 hp cars — AWD adds 0 kg of listed kerb there, unlike the first generation, where AWD on the 325 hp pair adds 84 kg (1896 − 1812).
Best mass-to-power: 410 hp FWD 3.6 AT at 4.58 kg/hp. Worst: restyled 309 hp cars at 5.90 kg/hp. The 416 hp restyled turbo is 4.78 kg/hp — still heavier per horse than either first-generation 410 hp 3.6 AT.
Ground clearance is 130 mm on three first-generation versions and 155 mm on 410 hp FWD 3.6 AT (25 mm more). After restyling, clearance is not measured. Wheel sizes are listed only on that same 410 hp FWD 3.6 AT. Cadillac XTS length, width and a size comparison in feet are not in these data.
Chassis language is the same on every version: Independent, spring front and rear; Ventilated disc front; rear listed as Disc ventilated.
Which Cadillac XTS version to choose
If you want the quickest measured sprint. First-generation 3.6 AT at 410 hp, either drive: 5.7 s to 100 km/h. FWD and AWD are tied on that number. Choose FWD if you also want the only listed wheels, the only Front, longitudinal engine placement, the only 155 mm clearance, and the lowest kg/hp (4.58). Choose AWD if you want a recorded 250 km/h top speed and recorded consumption (14.7 / 9.8 / 12.4); those three are not measured on the FWD turbo.
If you want the most horsepower on the list. Restyled 3.6 V6 T AWD AT: 416 hp, 500 Nm from 1900 rpm, AWD, 92 fuel. You give up measured 0–100 and top speed, carry the highest kerb (1990 kg), and use the highest highway figure in the file (10.2 L/100 km). Versus first-generation 410 hp AWD 3.6 AT you gain 6 hp and 94 kg.
If you want the lightest, cheapest-to-run non-turbo in the first generation. 3.6 AT 325 hp FWD: 1812 kg, 6.7 s, 250 km/h, 13.8 / 8.4 / 11.1, 130 mm. AWD on the same 325 hp name adds 84 kg and 0.2 s and 0.3 L/100 km on the highway, with mixed unchanged at 11.1.
If you want AWD without turbo after 2017. 3.6 V6 AWD AT (309 hp): same 1824 kg as the FWD restyle twin, so listed weight does not punish AWD. You lose 16 hp versus the first-generation 325 hp cars and you have no measured 0–100.
If you want the lowest city consumption in the file. Restyled FWD 3.6 V6 AT: 12.3 L/100 km city, 8.4 highway, 309 hp, 1824 kg, 92 fuel. That is the economy pick. It is also the weakest specific output (86.7 hp/L) and 5.90 kg/hp.
If you are looking at 2013 Cadillac XTS horsepower or 2013 specs. You are choosing among the four 3.6 AT versions: 325 hp FWD, 325 hp AWD, 410 hp FWD, 410 hp AWD. There is no 309 hp or 416 hp car in that year window.
If you are looking at a 2019 Cadillac XTS. Only the three restyled names exist. There is no FWD turbo after restyling: turbo is AWD-only as 3.6 V6 T AWD AT.
What “the extra hardware” buys, in numbers only (no prices in these data). Turbo on the first generation buys +85 hp and +129 Nm versus 325 hp, 1.0–1.2 s off 0–100, and on AWD +0.9 L/100 km city and +1.1 highway versus 325 hp AWD. AWD on 325 hp buys four-wheel drive for +84 kg and +0.2 s. AWD on 410 hp buys four-wheel drive for +19 kg (1896 − 1877) with 0–100 unchanged at 5.7 s. Restyling buys 92 fuel and unique version names, cuts non-turbo power by 16 hp, adds 6 hp to the turbo peak, and on the turbo AWD adds 94 kg versus the earlier 410 hp AWD 3.6 AT.
Length, width, oil grade, air-filter part numbers, engine-bay layout, check-engine causes, and sale prices are not measured here; a choice among these seven rows can still be made from horsepower, drive, kerb weight, and the consumption figures that exist.
