Chrysler 300M: which version to buy

Between the two Chrysler 300M versions in this catalogue — 2.7 AT and 3.5 AT — the buying choice is arithmetic, not a story about generations. There is 1 generation, a Sedan only, from 1998-06-01 to 2004-02-29.

Between the two Chrysler 300M versions in this catalogue — 2.7 AT and 3.5 AT — the buying choice is arithmetic, not a story about generations. There is 1 generation, a Sedan only, from 1998-06-01 to 2004-02-29. Both cars share Gasoline, a 6-cylinder V-shaped layout, 4 valves per cylinder, No boost, Front, longitudinal placement, Distributed injection (multi-point), a 4-speed Automatic, FWD, a 64 L tank, and 130 mm ground clearance. What you actually buy extra on 3.5 AT is 49 hp (252 vs 203), 82 Nm (340 vs 258), 1.4 s quicker 0–100 km/h (8.8 vs 10.2), and 30 km/h more top speed (240 vs 210), for 20 kg more kerb weight (1630 vs 1610). Fuel use is measured only on 2.7 AT (14.7 / 8 / 10.5 L/100 km city / highway / mixed); on 3.5 AT those figures are not measured. Wheel sizes are listed only on 2.7 AT (225/55 R17, 225/60 R16); on 3.5 AT they are not measured. Searches for a Chrysler 300M V8, Special, or year-by-year 1999–2004 splits are outside this dataset: here there are two named versions, not eight model years and not a V8.

Chrysler 300M generations

1 generation (key 1012, labelled 1 generation) ran 1998-06-01–2004-02-29 as a Sedan with 2 versions: 2.7 AT and 3.5 AT. Both versions use the same start and stop dates as the generation. There is no second generation in the data, so there is no generation-to-generation change in body, drive, gearbox type, or tank size to weigh. A 1999, 2000, 2001, 2002, 2003, or 2004 Chrysler 300M in this catalogue is still this one generation and still one of those two names.

Chrysler 300M specs and engine table

Exact version names as in the database:

2.7 AT engine size is 2736 cc. Power per litre is 203 / 2.736 ≈ 74.2 hp/L. Peak torque sits at 4850 rpm.

3.5 AT engine size is 3518 cc — 782 cc more. Power per litre is 252 / 3.518 ≈ 71.6 hp/L, about 2.6 hp/L lower than 2.7 AT, so the extra output comes from capacity, not a denser tune. Compression ratio is 10; bore × stroke is 96 × 81. Those two geometry figures are not measured on 2.7 AT. Peak torque on 3.5 AT arrives at 4000 rpm, 850 rpm earlier than on 2.7 AT.

Both engines: Gasoline, 6 cylinders, V-shaped, 4 valves per cylinder, No boost, Front, longitudinal, Distributed injection (multi-point), fuel 95. Chrysler 300M engine-bay, oil, swap, and “engine for sale” queries are not answered by this catalogue; only the spec rows above are measured.

Front and rear suspension on both versions: Independent, spring. Front and rear brakes on both: Disc.

Chrysler 300M horsepower, 0–100, and mpg

2.7 AT: 0–100 km/h 10.2 s, top speed 210 km/h. City 14.7 L/100 km, highway 8 L/100 km, mixed 10.5 L/100 km. CO2 not measured. Eco class not measured.

3.5 AT: 0–100 km/h 8.8 s (1.4 s quicker), top speed 240 km/h (30 km/h higher). City, highway, and mixed consumption not measured. CO2 not measured. Eco class not measured. Do not treat missing mpg as “the 3.5 uses nothing”; it is unlisted.

Kerb-weight power: 2.7 AT is 1610 / 203 ≈ 7.93 kg/hp (about 126 hp per tonne). 3.5 AT is 1630 / 252 ≈ 6.47 kg/hp (about 155 hp per tonne). The 20 kg penalty is about 1.2% of 1610 kg; the 49 hp gain is about 24% of 203 hp. That is the whole performance argument for 3.5 AT.

Chrysler 300M weight, dimensions, and wheels

Kerb and gross weight are measured; exterior length/width/height are not measured on either version, so “Chrysler 300M dimensions” in the sense of body size cannot be filled from this data.

Payload from the two masses: 2.7 AT 2100 − 1610 = 490 kg; 3.5 AT 2120 − 1630 = 490 kg. Same payload, same 130 mm clearance, same 64 L tank. Mixed 10.5 L/100 km on 2.7 AT implies a theoretical mixed range near 64 / 10.5 × 100 ≈ 610 km; 3.5 AT range from consumption is not measured.

Which Chrysler 300M version to choose

There is no generation fork. Choose 2.7 AT or 3.5 AT.

Choose 2.7 AT if you want the only version with measured economy (14.7 / 8 / 10.5 L/100 km), listed wheels (225/55 R17 and 225/60 R16), lower kerb weight (1610 kg), and you accept 203 hp, 258 Nm, 10.2 s to 100 km/h, and 210 km/h. Specific output is slightly higher (≈ 74.2 hp/L). Highway 8 L/100 km is the only highway figure in the model.

Choose 3.5 AT if the extra 49 hp and 82 Nm matter more than the unlisted mpg. You get 252 hp at 6400 rpm, 340 Nm at 4000 rpm, 8.8 s, 240 km/h, displacement 3518 cc, compression 10, and 96 × 81 geometry. You pay 20 kg kerb and 20 kg gross. Wheels and all three consumption figures remain not measured.

What the “extra money” cannot be priced here: this catalogue has no prices and no “for sale” data. What it buys in hardware is the larger Gasoline 6-cylinder unit and the performance deltas above — not AWD, not more gears, not another body, not more tank, not more clearance, not more payload.

Queries for Chrysler 300M Special, V8, or a unique 2004 vs 1999 spec sheet: this file has one generation and two version names. A 1999 or 2004 car is still 2.7 AT or 3.5 AT as tabled. Interior is not measured. Engine oil spec is not measured.
