The current Mercedes-Benz C-Class heralded major changes for the once-conservative German manufacturer when it was introduced in 1994. It was designed, equipped, and priced for value, a definite change of direction for a company once best-known for premium luxury cars. But performance was and is part of the C-Class equation, too. Between 1995 and 1997, the C36 was offered, a car modified by Mercedes-Benz performance tuning partner AMG, with an enlarged, tuned version of the then-current 3.2-liter six-cylinder engine. It was a limited-production model, and discontinued when its engine was no longer available. The void at the top of the C-Class line didn't last long. It was filled midway through the 1998 model year bythe C43.

Also created by AMG, the C43 is a German embodiment of one of the grandest traditions in performance tuning: a big engine in asmall car. The engine in question is the 4.3-liter (260 cu. in.)aluminum alloy V8 first introduced in the 1998 E430 and also found in the newly-introduced CLK430 coupe. In those cars, it develops a respectable 275 horsepower. In C43 tune, a healthy 302 horses are found under the unassuming C-Class hood. The engine is light for a large V8; the C43 weighs only 132 pounds more than a C280. As aresult, weight distribution is not adversely affected. Ultra-low profile tires mounted on 17-inch AMG wheels and other suspension modifications improve cornering abilities with little reduction in ride comfort.

Only 1500 C43s will be made over a three-year period, with the bulk of production in the 1999 model year. But the C43's performance attitude carries over to the other C-Class sedans this year, too. The V6-powered C280 is smooth, sophisticated, and very well-balanced. The entry-level C230 gets a major boost - it's now called the C230 Kompressor and has the supercharged four-cylinder engine from the SLK sports car.

To say that my time with the C43 was entertaining and enjoyable would be serious understatement. But, unlike many "tunercars", the C43 is perfectly acceptable as daily transportation. It is comfortable, relatively quiet (except for a wonderful V8 growl), and roomy enough for four people. It is a compliment to the solidity of the C-Class chassis structure that it works so well.

APPEARANCE: The C43 is relatively stealthy for a high-performance car. Differences in appearance between it and the other C-Class cars are minimal. The 17-inch AMG alloy wheels are the mostobvious, but are the same basic design as the 16-inch wheels that are part of the Sport Package available on the C280 and C230K. Deeper, more sculpted front and rear lower bumper fascias and matching rocker panels are not all that obvious. The "AMG" and "C43" badgingon the trunk lid will be read only by accomplished speed readers. Other C-Class Benzes, however, do not have the twin chrome-tipped AMG-badged exhausts producing a deep V8 rumble.

COMFORT: The C43 does differ from the other C-Class members inside, again thanks to AMG. Special heated sports seats incorporating pneumatic lumbar, side, and thigh support, and the thick-rimmed,leather-covered steering wheel are designed for serious driving. My test car had the two-tone, black and silver, interior color scheme, with silver inserts in the seating areas. They looked and felt great. Black-on-white instruments with AMG badging are also unique to the C43.Other interior features are pretty much standard C-Class, including room for four adults and a large, useful trunk.

SAFETY: The C43 has the full complement of Mercedes-Benz safetyequipment, including safety cage chassis construction,and front side air bags. Active safety is enhanced by strong antilock brakes with Brake Assist emergency stopping assistance, all-speed traction control, and ESP stability control.

ROADABILITY: Thanks to the very firm and well-controlled AMG-uned suspension and monstrous contact patch of the 225/45 x 17"front and 245/40 x 17" rear tires, the C43 sticks to the pavement extremely well, with excellent handling characteristics. Powerful,short-wheelbase cars can be tricky to keep in control, but the C43 isstable and assured. Huge vented, antilock brakes at all four wheelsensure near-race car stopping ability. If not quite as comfortable in ridequality as other C-Class cars, the C43 is not harsh or uncomfortable,and is as well-suited to a (quick) run to the grocery store as it is toperformance driving.

PERFORMANCE: Although the 4.3-liter V8 is basically the same asthat used other Benzes, internal modifications by AMG result in 302horsepower and 302 lb-ft of torque. A near back-to-back comparisonwith a new CLK430, which has the stock, 275-horsepower version ofthe same engine, was most enlightening. If the C43 has only 27 morehorsepower, they're large horses. There is enormous powerimmediately, and it never fades. The 5-speed automatic transmissionmitigates the power's effect when shifting, helping stability andundoubtedly prolonging tire life. The engine produces a mostsatisfying, muscular V8 roar.

CONCLUSIONS: The Mercedes-Benz C43 combination of Europeanchassis sophistication with V8 power makes for a very classy musclecar that is also works for everyday use. C43 = DTR + NASCAR!

Mercedes-Benz C43 AMG Problems

Brakes
  • Due to the size and materials of the brakes on these vehicles, the brakes start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
  • Brake fluid should be flushed every two years to prevent premature anti-lock brake system (ABS) failure.
Engine
  • Oil leaks from the PCV vent housings on the valve covers and inspection plates on the front of the engine are common.
  • The rubber bond in the harmonic balancer can decay, which causes the balancer to move and work its way into the timing chain cover. If the balancer comes into contact with the timing cover while the engine is running, it will fracture and damage the timing case and potentially other surrounding parts. The harmonic balancer should be inspected at every service.
  • Oil leaks from the oil level sensor are common.
  • The crankshaft position sensors tend to fail.  A symptom of this is the engine will crank, but not start, especially when the engine is warm.  The car may start again if it is left to cool off.  If it does start, it can run roughly, or have poor performance.  Our technicians report that communicating specific symptoms like these to your technician can save diagnostic time.
Exhaust & Emissions
Suspension & Steering
  • Irregular and premature tire wear can be caused by the lower control arm bushings cracking and causing excessive movement at the control arm pivot point. Ball joints can also wear out prematurely, causing similar tire wear symptoms.
  • The tie rod ends, drag link, and idler arm in the linkage of the steering system can wear out.
  • There is a steering dampening shock that will leak fluid when it goes bad.
Drive Train
  • A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
  • High mileage or older vehicles develop leaks at the differential seals and cover; the whole unit needs to be resealed to repair the leaks.
  • The wire connector on the transmission leaks fluid into the wiring harness.  If it is not repaired, the oil will migrate through the wiring harness and damage the transmission control module.  A new harness and control module will be needed to fix the problem.
Electrical & Lights
  • Rear tail light housings can fail causing the brake lights to be inoperative.
  • Brake light switch failure can cause the ESP and BAS warnings to illuminate.
Heating & Air Conditioning
  • The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not cycle on, the AC system will not blow cold air. If the AC compressor is stuck on, the air will be very cold at first, before warming up.
  • Leaks at the AC compressor, hose manifold for the compressor, or the evaporator core can cause poor AC performance.
  • Vacuum manifolds for the climate control actuator can leak causing poor or no operation of the control flaps.
