Hawtai B21

Hawtai B21: which version to buy — 2.0 MT vs 2.0 AT

The Hawtai B21 catalogue has one generation (March 2013–August 2017) and two versions: 2.0 MT and 2.0 AT. Both are Sedan, FWD, 136 hp / 180 Nm from a 1997 cm³ Gasoline engine, kerb weight 1461 kg, 0–100 in 14.2 s. The buy decision is not “which engine” or “which generation.” It is 5-speed Manual versus 4-speed Automatic on the same chassis numbers.

The Hawtai B21 catalogue has one generation (March 2013–August 2017) and two versions: 2.0 MT and 2.0 AT. Both are Sedan, FWD, 136 hp / 180 Nm from a 1997 cm³ Gasoline engine, kerb weight 1461 kg, 0–100 in 14.2 s. The buy decision is not “which engine” or “which generation.” It is 5-speed Manual versus 4-speed Automatic on the same chassis numbers.

Specs that do not change between versions

If a number is identical, it cannot justify picking one car over the other. For 2.0 MT and 2.0 AT the shared sheet is:

2.0 MT and 2.0 AT therefore share power per litre, weight per horsepower, and the measured sprint. Arithmetic on the shared engine: 136 hp ÷ 1.997 L ≈ 68.1 hp per litre. Weight per horsepower: 1461 kg ÷ 136 hp ≈ 10.74 kg per hp. Torque per litre: 180 Nm ÷ 1.997 L ≈ 90.1 Nm per litre. Peak power is at 6000 rpm; peak torque is at 4000 rpm — a 2000 rpm gap on both cars.

Compression ratio and bore × stroke are not measured on either version. Do not treat them as differentiators.

The only measured difference: gearbox

The Automatic on 2.0 AT is a 4-speed unit. The Manual on 2.0 MT is a 5-speed unit. That is one extra ratio on the Manual (5 − 4 = 1). Catalogue 0–100 is the same 14.2 s on both, so the extra ratio does not show up as a faster sprint in these data. Kerb weight is also the same 1461 kg, so the Automatic is not listed as a heavier car here.

Fuel use is not measured for city, highway, or combined on either version. You cannot pick 2.0 MT or 2.0 AT on mpg from this catalogue: both are blank.

Power, weight, and “what the extra money buys”

There is no price in the data, so “extra money” can only mean what the Automatic specification buys versus the Manual, not a currency amount.

What 2.0 AT buys versus 2.0 MT:

• Gearbox type: Automatic instead of Manual
• Ratio count: 4 instead of 5 (−1 speed)

What 2.0 AT does not buy versus 2.0 MT (difference = 0):

• Horsepower: 136 vs 136
• Kilowatts: 100 vs 100
• Torque: 180 vs 180
• Displacement: 1997 vs 1997
• 0–100: 14.2 vs 14.2
• Kerb weight: 1461 vs 1461
• Tank: 55 vs 55
• Clearance: 126 vs 126
• Drive: FWD vs FWD
• Boost: No vs No

If the Automatic is the more expensive used car in the market, the catalogue says that spend buys a 4-speed Automatic and does not buy more power, a quicker 0–100, a larger tank, more clearance, or a different body. If the Manual is cheaper, you give up Automatic shifting and you keep the same 136 hp, 180 Nm, 14.2 s, and 1461 kg.

Generations: there is nothing to choose

Hawtai B21 has 1 generation, 1 body type (Sedan), 2 versions, production 2013-03-01 to 2017-08-31. There is no second generation, no restyling row, and no year-split of engines. A 2013 2.0 MT and a 2017 2.0 MT sit in the same generation with the same measured numbers in this dataset. Same for 2.0 AT.

You cannot “buy the later generation for more power”: later years are still 136 hp, 180 Nm, 1997 cm³, 14.2 s, 1461 kg, 126 mm, 55 L.

Dimensions and weight when choosing

Both versions: kerb 1461 kg, gross weight not measured, clearance 126 mm, tank 55 L, wheels not measured.

Clearance 126 mm is the same whether you take 2.0 MT or 2.0 AT. Tank 55 L is the same; without measured mpg you cannot convert that tank into range. Wheel sizes being not measured means tyre choice is not a catalogue split between versions.

Independent, spring suspension front and rear, Ventilated disc front and Disc rear — identical. Chassis spec does not pick a winner.

Performance and economy: what is measured vs not

Measured for both 2.0 MT and 2.0 AT:

• 0–100: 14.2 s
• Power: 136 hp / 100 kW at 6000 rpm
• Torque: 180 Nm at 4000 rpm

Not measured for both:

• Top speed
• City consumption
• Highway consumption
• Combined consumption
• CO₂
• Eco class

A 14.2 s 0–100 on 1461 kg with 136 hp is consistent with ≈ 10.74 kg/hp. The Automatic does not change that figure. Anyone shopping on “mpg” or “top speed” will not find a version that has those numbers filled in.

Which version to choose

Choose 2.0 MT if you want the 5-speed Manual. You get the same 136 hp, 180 Nm, 1997 cm³ Gasoline engine, FWD, 14.2 s 0–100, 1461 kg, 126 mm clearance, and 55 L tank as the Automatic. You get one more gearbox speed (5 vs 4). You do not get a lighter kerb weight in these data (1461 kg on both).

Choose 2.0 AT if you want Automatic shifting. You accept 4 speeds instead of 5. You do not gain horsepower, torque, a faster 0–100, more clearance, or a bigger tank. 0–100 stays 14.2 s. Boost stays No. Drive stays FWD.

Do not choose by generation — there is only 1 generation.

Do not choose by engine size or fuel type — both are 1997 cm³ Gasoline, 95, 4 Inline, Front, transverse, Distributed injection (multi-point), No boost.

Do not choose by 0–100, mpg, or top speed — 0–100 is tied; mpg and top speed are not measured.

Do not invent a third version — the catalogue lists 2 modifications: 2.0 MT and 2.0 AT. Names must stay exactly 2.0 MT and 2.0 AT.

Reliability and problems (what the numbers can and cannot say)

This dataset has no failure rates, recalls, or workshop hours. Reliability shopping cannot be scored from horsepower or gearbox count. What you can say without leaving the numbers:

• Both versions use the same 136 hp / 180 Nm / 1997 cm³ Gasoline 4 Inline layout with No boost and Distributed injection (multi-point).
• The only mechanical split is Manual 5 vs Automatic 4.
• If a used example has gearbox issues, the relevant catalogue identity is 2.0 MT (Manual, 5) or 2.0 AT (Automatic, 4) — not a different engine family, because there is no second engine in the list.
• Service items that scale with oil volume, cooling, or brakes are not split by version in these specs: same weight, same brake types, same suspension labels.

Short decision table

Hawtai B21 buying, in this catalogue, is a gearbox choice between 2.0 MT and 2.0 AT. Every other measured figure is a tie.
