What engine does the BMW E46 330i use?

The E46 330i uses the BMW M54B30 naturally aspirated 3.0-litre inline-six with double-VANOS (variable valve timing on both camshafts) and an aluminium block, producing 231 PS (228 hp / 170 kW) at 5,900 rpm and 300 Nm (221 lb-ft) at 3,500 rpm. The engine ran unchanged from the 330i sedan's 2000 introduction through to the end of E46 sedan production in May 2005 — no mid-generation engine swap.

How does the BMW E46 330i differ from the E90 330i?

The E46 330i uses the M54B30 with double-VANOS and an aluminium block; the E90 330i successor uses the N52B30 with Valvetronic, double-VANOS, and a magnesium-aluminum composite block. The E90 is larger (2,760 mm wheelbase vs 2,725 mm on the E46), heavier, and significantly more electronically complex. The E46 is widely regarded as the more analog driver's car; the E90 offers more comfort and features at the cost of additional service surface.

What are the most common problems on the BMW E46 330i?

Five well-documented failure modes: (1) cooling-system components — water pump, thermostat, plastic expansion tank cracking — at 60,000–100,000 miles; (2) CCV (crankcase ventilation valve) failure causing oil consumption; (3) DISA valve plastic-shaft fracture at 70,000–100,000 miles, the highest-severity item due to debris ingestion risk; (4) VANOS seal degradation causing rough cold-start and low-RPM hesitation; (5) rear subframe (rear axle carrier panel) cracking under the rear wheel arches, particularly on the 330i due to higher torque loading.

What is the BMW E46 330i ZHP?

The ZHP Performance Package was a factory option on E46 330i sedans in the US and Canada for model years 2003–2005. It revised the M54B30 with different camshafts and DME tuning to 235 hp at a 6,800 rpm redline, added stiffer suspension, a shorter 3.07:1 final drive, 18-inch Style 135 wheels, and Alcantara interior. The ZHP is a sub-variant of the 330i sedan, not a separate chassis entity, and commands a market premium.

BMW E46 330i: Distinction

BMW E46 330i is not the BMW E90 330i (fifth-generation successor with the N52B30, Valvetronic, and a magnesium-aluminum composite block); not the BMW E46 325i (M54B25 2.5-litre, 192 hp, lower torque, same chassis but different engine); not the BMW E46 M3 (S54B32 3.2-litre, 343 hp, wider body, motorsport engine, different car entirely); and not the BMW E46 330Ci coupé, 330i Touring estate, or 330Ci convertible (different body styles on the same platform — separate entities).
