1993 BMW 740i Specs: The E32’s Final Year, Examined

You’ve spotted a 1993 BMW 740i for sale. The paint is glossy, the interior smells like old leather, and the seller says it runs strong. But before you hand over cash, you need to know what you’re actually buying. The 1993 model year is special—it was the last year for the E32 generation, and it came with a few updates that make it different from earlier cars.

This article walks through the complete 1993 BMW 740i specs: the engine’s power and torque curves, transmission options, chassis dimensions, performance numbers, and the common trouble spots you’ll face owning one today. You’ll leave knowing exactly what to look for on a test drive and what repair bills might be waiting.

If you’re serious about maintaining one of these, a factory-level service manual is worth its weight in gold. The Bentley Publishers E38 manual covers the later 740i, but the engine and drivetrain fundamentals carry over. It’s a thick book with torque specs and wiring diagrams that will save you hours of guessing.

The M60 V8: What’s Under the Hood

The 1993 740i uses the M60B40, a 4.0-liter naturally aspirated V8. This engine gets a lot of attention because it was BMW’s first production V8 in years, and it’s a gem when it’s running right.

Here are the hard numbers:

• Displacement: 3,982 cc (243 cubic inches)
• Bore x stroke: 89.0 mm x 80.0 mm
• Compression ratio: 10.0:1
• Power: 282 hp at 5,800 rpm
• Torque: 295 lb-ft at 4,500 rpm
• Redline: 6,500 rpm
• Fuel system: Bosch Motronic 3.3 sequential fuel injection

The M60 is silky smooth and revs willingly. It pulls hard from 2,500 rpm, and the torque curve is flat enough that you rarely need to downshift. The 4.0-liter feels more muscular than the later 4.4-liter M62, partly because it’s slightly overbored and understressed.

One thing to know: the M60 has a notorious issue with the cylinder bore lining. BMW used a process called Nikasil, which can degrade when exposed to high-sulfur fuel. If the car ran on cheap gas in the mid-90s, the cylinders may be pitted, causing oil consumption and eventual failure. Check for blue smoke on startup and listen for a rhythmic knock at idle.

Transmission and Drivetrain

Every 1993 740i sold in North America came with a four-speed automatic—the ZF 4HP24. A five-speed manual was offered in Europe, but you won’t find one stateside without a conversion.

The 4HP24 is a robust gearbox. It handles the M60’s torque without complaint, and many have gone past 200,000 miles with regular fluid changes. The shift quality is smooth but a bit lazy by modern standards. There’s no sport mode, no paddle shifters—just a column shifter with D, 3, 2, and 1.

If you test drive one, pay attention to the 1-2 shift. A hard clunk or a flare (where the engine revs up without speed) means the clutch packs are worn. Rebuilding a 4HP24 runs about $1,500–$2,500, so it’s worth negotiating if the shift feels off.

The rear differential is a 2.93:1 ratio, which gives a good balance of acceleration and cruising economy. At 70 mph, the engine turns about 2,300 rpm—quiet, relaxed, and ready to pass without downshifting.

Dimensions, Weight, and Chassis

The 1993 740i rides on a 111.4-inch wheelbase and stretches 193.3 inches overall. It’s a big car, but not as enormous as the later E38. Curb weight is 4,145 pounds, which feels heavy in the parking lot but hides its mass once you’re moving.

Suspension is all independent: MacPherson struts up front, semi-trailing arms in the rear. The rear setup is old-school and can feel twitchy over bumps, but it gives the car a planted, direct feel that newer BMWs have traded for comfort. Steering is recirculating-ball with power assist—not rack-and-pinion—so there’s a hint of play on center, but it weights up nicely in corners.

Brakes are four-wheel discs with ABS, and they’re strong for the era. The front calipers are four-piston units that bite hard. If the pedal feels spongy, it’s usually old fluid or worn bushings, not a design flaw.

Performance Numbers: Real-World Testing

BMW claimed a 0-60 mph time of 6.8 seconds for the 1993 740i. Contemporary magazine tests recorded times between 6.5 and 7.0 seconds, depending on conditions. The quarter-mile runs about 15.1 seconds at 93 mph. Top speed is electronically limited to 128 mph.

Those numbers feel quick even today. The M60’s torque makes the car feel faster than the stopwatch suggests, especially from 30-70 mph. It’s not a sports car, but it will embarrass a lot of modern commuter sedans.

Fuel economy is the price you pay. The EPA rated it at 15 mpg city and 21 mpg highway. Real-world driving with mixed conditions lands around 17-18 mpg. On a long interstate trip, you might see 22-23 mpg if you keep it under 75 mph. The 21.5-gallon fuel tank gives you a cruising range of about 400 miles.

1993 vs. 1994: What Changed and Why It Matters

If you’re comparing a 1993 to a 1994, you need to know the differences. The 1994 model introduced the E38 chassis, which was completely redesigned. The E38 is lighter, stiffer, and has a more modern suspension setup. But the 1994 E38 740i used the same M60B40 engine, so the powertrain is nearly identical.

The E32 (1993) has a more analog feel—hydraulic steering, simpler electronics, and a cabin that’s mostly switchgear rather than screens. The E38 has a more refined ride and better corrosion protection. If you want a daily driver, the E38 is the better choice. If you want a classic with character and simpler wiring, the E32 wins.

There’s also the 740iL, the long-wheelbase version, which adds 4.7 inches of rear legroom. The 1993 740iL is rare—only a few hundred were sold—and it weighs about 100 pounds more. The extra weight barely affects performance, and the rear seat is genuinely limousine-like.

Spec	1993 BMW 740i (E32)	1994 BMW 740i (E38)
Engine	4.0L M60 V8	4.0L M60 V8
Power	282 hp @ 5,800 rpm	282 hp @ 5,800 rpm
Torque	295 lb-ft @ 4,500 rpm	295 lb-ft @ 4,500 rpm
Curb weight	4,145 lbs	4,055 lbs
Wheelbase	111.4 in	115.4 in
0-60 mph	6.8 sec (claimed)	6.9 sec (claimed)
Transmission	4-speed auto (ZF 4HP24)	5-speed auto (ZF 5HP30)
Suspension (rear)	Semi-trailing arms	Multi-link
Steering	Recirculating ball	Recirculating ball
Fuel economy (EPA)	15/21 mpg	15/22 mpg

The 1994 E38’s five-speed automatic is a notable upgrade. It has a taller overdrive and shifts more smoothly. But the E32’s four-speed is simpler to rebuild and less prone to electrical gremlins. For a weekend car, I’d take the E32. For a commuter, the E38.

Common Issues and What to Inspect Before Buying

You can’t buy a 30-year-old BMW without expecting some work. Here’s what fails most often on the 1993 740i.

Cooling system. The M60 runs hot, and the plastic expansion tank and radiator necks become brittle. If the cooling system hasn’t been replaced in the last five years, budget for it. A full overhaul—radiator, water pump, thermostat, hoses—costs around $800 in parts.

Valve cover gaskets. These leak oil onto the exhaust manifolds, causing a burning smell. It’s a $150 fix if you DIY, but the job takes a few hours because the intake manifold has to come off. Check the valley pan under the intake for oil puddles.

Front suspension bushings. The control arm bushings wear out every 60,000 miles. You’ll hear a clunk over bumps and feel a shimmy at highway speeds. Replacing both sides with quality parts runs about $400.

Electrical gremlins. The instrument cluster pixels fade, the window regulators fail, and the central locking system can act up. None of these are deal-breakers, but they’re annoying. Test every switch on your test drive.

Nikasil cylinder wear. This is the big one. If the car burns oil or has a rough idle, walk away. A compression test and a leak-down test will tell you the truth. Pay a mechanic $150 to do it before you commit.

One more thing: check the rust. The E32’s lower door skins and rear wheel arches are prone to corrosion. Surface rust is treatable; holes in the structure are not.

Frequently Asked Questions

Is the 1993 BMW 740i reliable as a daily driver?

It can be, but only if you’re willing to stay ahead of maintenance. The engine and transmission are robust; the weaknesses are cooling system parts, gaskets, and aged rubber. Budget $1,500–$2,000 per year for upkeep if you drive it regularly. If you can’t do your own labor, double that.

What oil should I use in the M60 V8?

BMW specified 10W-40 for most climates. A high-quality synthetic 10W-40 or 5W-40 with the BMW LL-98 spec is ideal. The M60 has hydraulic lifters, so consistent oil pressure matters. Change it every 5,000 miles, not the 15,000 miles BMW claimed in the manual.

Can I convert a 1993 740i to a manual transmission?

Yes, but it’s a serious project. You need the pedal box, clutch master cylinder, flywheel, and a Getrag 420G gearbox from an E34 540i or E39 540i. The transmission tunnel fits without major cutting, but the wiring for the reverse light and neutral safety switch needs custom work. Expect to spend $3,000–$5,000 in parts and a week of labor.

What’s the difference between a 740i and a 740iL?

The iL has a 4.7-inch longer wheelbase, all of it behind the B-pillar. Rear legroom goes from generous to limousine-like. The iL also came with rear side airbags as an option. Otherwise, the specs are identical. The iL is rarer, which helps resale value.

Is the 1993 740i a good investment?

Prices for clean E32s have been creeping up. A well-maintained 1993 740i with under 100,000 miles can fetch $8,000–$12,000. Low-mileage garage queens occasionally hit $15,000. It’s not a skyrocketing classic, but it’s no longer a depreciating asset. The key is condition—a rusted or Nikasil-damaged car is worth scrap value.

What I’d Do Before Buying One

You’ve read the specs and the problem areas. Now here’s a practical checklist for your test drive.

• Start it cold. Listen for a rough idle or a rhythmic knock that goes away as it warms up—that’s often Nikasil wear.
• Let it idle for 10 minutes and look for smoke from the exhaust. Blue smoke means oil burning.
• Drive it hard up a long hill. The transmission should shift firmly without slipping.
• Check the coolant for oil and the oil for coolant. Cross-contamination means a failed head gasket or oil cooler.
• Inspect the front tires for uneven wear—that points to worn suspension bushings.
• Press every button: windows, sunroof, seat adjustment, climate control. The pixel display on the radio is a common failure.
• Ask for service records. A car with a stack of receipts is worth $2,000 more than one without.

If the car checks out, you’re getting a genuine driver’s sedan with a legendary V8. The 1993 740i isn’t the most practical choice, but it rewards the person who respects its quirks. And if you’re doing your own wrenching, the service requirements are straightforward—no special tools needed for most jobs. For a deeper look at how this generation compares to its successor, the 1996 750iL offers a different flavor with the V12. And if you’re cross-shopping other 90s BMWs, the 1995 325i specs show how the brand balanced sport and luxury in the same era.
