Cadillac XT5

Generations: what actually changed between the three

What the restyling changed, in arithmetic on the given numbers:

1 generation ran from 2016-04-01 to 2019-05-31 with 4 versions. 1 generation, restyling starts 2019-06-01 with no stop date and 8 versions. 2 generation starts 2024-08-01 with no stop date and 0 versions — there is nothing to spec, nothing to compare, and nothing to buy under that heading until versions appear.

What the restyling changed, in arithmetic on the given numbers:

• Gears: 8 on every 1 generation XT5 → 9 on every 1 generation, restyling XT5.
• Tank: 72 L → 83 L (+11 L, +15.3%).
• The 2.0 AT turbo four: 258 hp / 192 kW at 5300 rpm and 400 Nm at 3000 rpm in 1 generation → 237 hp / 177 kW at 5000 rpm and 350 Nm at 4000 rpm on the main restyling 2.0 AT, or 200 hp / 147 kW at 5000 rpm and 350 Nm at 4000 rpm on the weakest restyling 2.0 AT. That is −21 hp (−8.1%) or −58 hp (−22.5%) versus the pre-restyle 2.0 AT, and −50 Nm (−12.5%) of torque, arriving 1000 rpm later.
• Bore × stroke on the 1998 cm³ four: 86 × 86 in 1 generation → 83 × 92.3 in 1 generation, restyling. Compression stays 9.5. Cylinders stay 4, layout Inline, boost Turbo, injection Direct injection (direct).
• The 3649 cm³ six does not change output: 314 hp / 231 kW at 6700 rpm, 367 Nm at 5000 rpm, compression 11.5, bore × stroke 95 × 85.8, 6 cylinders, V-shaped, boost No, on both 1 generation and 1 generation, restyling.
• In the restyling the same 3649 cm³ / 314 hp package is sold as both 3.7 AT and 3.6 AT. The name is not a second engine.
• The restyling adds a 2.0 AT at 200 hp that 1 generation never had.
• Fuel use, CO₂ and eco class: not measured on all four 1 generation versions. The only measured fuel figures in the whole model sit on restyling 3.7 AT AWD and restyling 3.6 AT AWD (same numbers: 13.1 / 9.4 / 11.8 L/100 km).

2 generation changed the calendar (from 2024-08-01) and the version count (to 0). It did not add an engine, a gearbox, a drive layout, a weight, or a performance figure in these data.

Engines and specs

Use the catalogue names exactly. Several rows share 2.0 AT, 3.6 AT or 3.7 AT; they are told apart by hp and drive.

Power per litre (hp ÷ litres of displacement): restyling 2.0 AT 200 hp = 100.1 hp/L; restyling 2.0 AT 237 hp = 118.6 hp/L; 1 generation 2.0 AT 258 hp = 129.1 hp/L; every 3.6 AT / 3.7 AT at 314 hp and 3649 cm³ = 86.1 hp/L. The naturally aspirated six is the least dense engine in the catalogue; the pre-restyle turbo four is the densest.

Torque per litre: restyling 1998 cm³ fours at 350 Nm = 175.2 Nm/L; 1 generation 2.0 AT at 400 Nm = 200.2 Nm/L; the 3649 cm³ six at 367 Nm = 100.6 Nm/L. The 1 generation 2.0 AT out-torques every six in this model by 33 Nm (400 vs 367) from a displacement that is 1651 cm³ smaller.

Two restyling 2.0 AT rows at 237 hp FWD are identical in every measured field in these data (1776 kg, 9-speed, 83 L, 200 mm, same wheels, same brakes). They are not two different cars on paper.

Performance and economy

Measured 0–100 km/h exists on 5 of 12 listed versions. The rest are not measured.

Fastest to 100 km/h: 1 generation 3.7 AT FWD — 6.4 s. Then 1 generation 3.7 AT AWD and restyling 3.7 AT AWD and restyling 3.6 AT AWD — all 6.6 s. Then 1 generation 2.0 AT AWD — 6.8 s. Then 1 generation 2.0 AT FWD — 6.9 s. AWD costs 0.2 s on the 1 generation 3.7 AT (6.6 vs 6.4) and saves 0.1 s on the 1 generation 2.0 AT (6.8 vs 6.9). Restyling 2.0 AT in all four hp/drive combinations: 0–100 not measured. Restyling 3.7 AT FWD and 3.6 AT FWD: 0–100 not measured.

Top speed, where measured: 1 generation 3.7 AT FWD 248 km/h (highest in the model); 1 generation 3.7 AT AWD, restyling 3.7 AT AWD and restyling 3.6 AT AWD 245 km/h; 1 generation 2.0 AT FWD 233 km/h; 1 generation 2.0 AT AWD 230 km/h; restyling 2.0 AT 200 hp AWD 210 km/h. Gap from the slowest measured XT5 to the fastest: 38 km/h. Restyling 2.0 AT 237 hp FWD and AWD: top speed not measured. Restyling 3.7 AT FWD and 3.6 AT FWD: top speed not measured.

Fuel: only restyling 3.7 AT AWD and restyling 3.6 AT AWD have figures — city 13.1, highway 9.4, mixed 11.8 L/100 km. CO₂ not measured. Eco class not measured. Every other version: city, highway and mixed not measured. You cannot pick a “more economical” 2.0 AT from these data; the four-cylinder has no consumption number at all.

Specific output vs the clock: 1 generation 2.0 AT FWD makes 258 hp from 1998 cm³ and does 0–100 in 6.9 s; 1 generation 3.7 AT FWD makes 314 hp (+56 hp, +21.7%) from 3649 cm³ and does it in 6.4 s (−0.5 s). That is 56 extra hp for half a second. AWD on the same 3.7 AT gives the extra 123 kg (1931 vs 1808) and +0.2 s and −3 km/h.

Dimensions and weight

Gross vehicle weight: not measured on every version. Ground clearance: 200 mm on every version that lists it. Wheels: 235/65 R18 and 235/55 R20 on every version that lists them. Tank: 72 L (1 generation) or 83 L (1 generation, restyling). 2 generation: tank, weight, clearance, wheels all not measured.

Kerb weight clusters, not a spread:

• 1776 kg — restyling 2.0 AT 237 hp FWD and restyling 2.0 AT 237 hp AWD (same kerb on both drives in these data).
• 1808 kg — 1 generation 2.0 AT FWD; 1 generation 3.7 AT FWD; restyling 3.7 AT FWD; restyling 3.6 AT FWD.
• 1931 kg — restyling 2.0 AT 200 hp AWD; 1 generation 2.0 AT AWD; 1 generation 3.7 AT AWD; restyling 3.7 AT AWD; restyling 3.6 AT AWD.

AWD vs FWD on the six: +123 kg (1931 − 1808). AWD vs FWD on 1 generation 2.0 AT: +123 kg. Restyling 2.0 AT 237 hp lists 1776 kg for both FWD and AWD — the AWD penalty is 0 kg on that row, which is a data fact, not a reason to assume the cars weigh the same on a scale you cannot see here.

kg per hp (kerb ÷ hp):

• Restyling 2.0 AT 200 hp AWD: 1931 / 200 = 9.66 kg/hp (worst).
• 1 generation 2.0 AT AWD: 1931 / 258 = 7.48 kg/hp.
• Restyling 2.0 AT 237 hp: 1776 / 237 = 7.49 kg/hp.
• 1 generation 2.0 AT FWD: 1808 / 258 = 7.01 kg/hp.
• Restyling / 1 generation 3.7 AT / 3.6 AT AWD: 1931 / 314 = 6.15 kg/hp.
• Restyling / 1 generation 3.7 AT / 3.6 AT FWD: 1808 / 314 = 5.76 kg/hp (best).

The 200 hp restyling 2.0 AT is the only XT5 above 9 kg per hp. It shares the 1931 kg kerb of the AWD sixes while making 114 hp less (314 − 200).

Front brakes are Ventilated disc on every version. Rear brakes are Disc ventilated on every version except the restyling 2.0 AT 200 hp AWD, which is Disc. Suspension front and rear: Independent, spring on every version. Those chassis labels do not separate versions except that one rear-brake wording on the 200 hp row.

mpg and fuel — what you can and cannot claim

There is no mpg figure in the data. The only consumption block is 13.1 / 9.4 / 11.8 L/100 km on restyling 3.7 AT AWD and restyling 3.6 AT AWD, tank 83 L. Mixed 11.8 L/100 km into 83 L is 703 km of theoretical mixed range if the tank were used in full at that rate (83 ÷ 11.8 × 100). Highway 9.4 L/100 km into 83 L is 883 km. City 13.1 L/100 km into 83 L is 634 km. Those three ranges apply only to those two AWD sixes. 1 generation tanks are 72 L with consumption not measured, so range is not measured. Every 2.0 AT: consumption not measured, range not measured. CO₂ not measured on all. Eco class not measured on all.

Problems and reliability

No failure rates, recall counts, service intervals or reliability scores are in these data. Problems: not measured. Reliability: not measured. Do not read silence as “no problems”.

What you can rank without those scores: mechanical sameness. The restyling 3.6 AT and 3.7 AT match on hp, kW, rpm, Nm, displacement, cylinders, layout, boost, injection, compression, bore × stroke, fuel, gearbox type, gear count, tank, clearance and wheels — FWD to FWD (1808 kg) and AWD to AWD (1931 kg, 6.6 s, 245 km/h, 13.1 / 9.4 / 11.8). Choosing 3.6 AT versus 3.7 AT in 1 generation, restyling is a name choice, not an output choice. Choosing 1 generation 3.7 AT versus restyling 3.7 AT is an 8-speed / 72 L versus 9-speed / 83 L choice at the same 314 hp and 367 Nm; 0–100 is measured on both AWD rows at 6.6 s and both AWD top speeds at 245 km/h. The FWD 1 generation 3.7 AT is the only six with 6.4 s and 248 km/h.

Which version to choose

If you want the lowest measured 0–100 and the highest measured top speed: 1 generation 3.7 AT FWD — 6.4 s, 248 km/h, 314 hp, 367 Nm, 1808 kg, 5.76 kg/hp, 8-speed Automatic, 72 L, FWD. That is the performance peak in the catalogue. The same engine with AWD is +0.2 s, −3 km/h, +123 kg.

If you want six-cylinder output on the restyling (9 gears, 83 L): restyling 3.7 AT AWD or restyling 3.6 AT AWD — same 314 hp, 6.6 s, 245 km/h, 13.1 / 9.4 / 11.8 L/100 km, 1931 kg. Restyling 3.7 AT FWD and 3.6 AT FWD keep 314 hp and 1808 kg but 0–100, top speed and fuel are not measured. There is no numerical reason in these data to pay a difference between the names 3.6 AT and 3.7 AT in the restyling.

If you want the strongest four-cylinder: 1 generation 2.0 AT — 258 hp, 400 Nm at 3000 rpm, 129.1 hp/L. FWD: 1808 kg, 6.9 s, 233 km/h. AWD: 1931 kg, 6.8 s, 230 km/h. Versus the restyling 237 hp 2.0 AT that is +21 hp and +50 Nm at 1000 rpm lower. Versus the restyling 200 hp 2.0 AT that is +58 hp and +50 Nm. Versus the FWD six, the FWD 2.0 AT is −56 hp, +33 Nm, +0.5 s, −15 km/h, same 1808 kg.

If you are buying a restyling four: take 2.0 AT 237 hp, not 2.0 AT 200 hp. The 237 hp rows are +37 hp (+18.5%) at the same 350 Nm, same 1998 cm³, same 9-speed. FWD and AWD 237 hp both list 1776 kg — 155 kg lighter than the 200 hp AWD’s 1931 kg. kg/hp improves from 9.66 to 7.49. The 200 hp row is also the only one with rear brakes labelled Disc rather than Disc ventilated, and the only restyling four with a measured top speed (210 km/h), which is 20 km/h below the pre-restyle AWD four and 38 km/h below the FWD six. 0–100 on all restyling fours: not measured. Drive on the 237 hp restyling 2.0 AT: FWD versus AWD does not change the listed kerb, tank, gears or wheels; AWD is the extra driveline, not extra measured performance, because performance on those rows is not measured.

If you want AWD with a measured sprint: 1 generation 2.0 AT AWD (6.8 s, 230 km/h, 258 hp) or 1 generation 3.7 AT AWD (6.6 s, 245 km/h, 314 hp) or restyling 3.7 AT / 3.6 AT AWD (6.6 s, 245 km/h, 314 hp, and the only fuel figures). Restyling 2.0 AT AWD at 237 hp: AWD is listed, sprint is not measured. Restyling 2.0 AT AWD at 200 hp: AWD is listed, top speed 210 km/h, sprint not measured.

If you want the lightest listed XT5: restyling 2.0 AT 237 hp at 1776 kg — 32 kg under the 1808 kg FWD cluster and 155 kg under the 1931 kg AWD cluster. That is the weight win. It is not a measured-sprint win.

If you want the extra 11 L of tank and the extra gear: any 1 generation, restyling version versus any 1 generation version. That is the restyling’s only fully measured, model-wide hardware step. It is not more hp on the four (the four loses 21 or 58 hp) and it is not more hp on the six (314 hp on both sides).

If you want 2 generation: there are 0 versions. Specs, engines, 0–100, mpg, dimensions: not measured. Wait for versions; do not treat the generation date 2024-08-01 as a car.

What “extra” buys, using only these numbers (no prices in the data): moving from restyling 2.0 AT 200 hp AWD to restyling 2.0 AT 237 hp buys 37 hp and 155 kg less listed kerb at the same 350 Nm. Moving from restyling 2.0 AT 237 hp to 1 generation 2.0 AT buys 21 hp and 50 Nm and a measured 6.8–6.9 s, at the cost of one gear (9 → 8) and 11 L of tank (83 → 72). Moving from 1 generation 2.0 AT FWD to 1 generation 3.7 AT FWD buys 56 hp, 0.5 s and 15 km/h, at −33 Nm and +1651 cm³. Moving from FWD six to AWD six buys 123 kg and, where both are measured, 0.2 s and 3 km/h given back. Moving from restyling 3.6 AT to restyling 3.7 AT (same drive) buys 0 hp, 0 Nm, 0 kg.

Pick by the row, not by the three-character name: 2.0 AT in this model is 200, 237 or 258 hp; 3.7 AT is always 314 hp but FWD or AWD and 8- or 9-speed; 3.6 AT is the restyling’s second label for that same 314 hp six.
