The Mitsubishi Lancer Evolution IX is Beautifully Engineered

Many machines on Ix. New machines. Better than those on Richese.

The Mitsubishi Lancer Evolution, colloquially known as the Lancer Evo or Evo, is a high-performance sedan manufactured by Mitsubishi Motors. There have been ten official versions to date, and the designation of each model is most commonly a roman numeral. All use two litre, turbocharged engines and four-wheel drive systems.

Mitsubishi introduced the Lancer Evolution IX in Japan on March 3, 2005, and exhibited the car at the Geneva Motor Show for the European market the same day. The North American markets saw the model exhibited at the New York International Auto Show the following month. The 2.0 L Mitsubishi 4G63 engine gained MIVEC technology (variable valve timing), and a revised turbocharger design boosting official power output at the crankshaft to 291 PS (214 kW; 287 hp) and torque to 392 N·m (289 lb·ft).

The USDM Lancer Evolution IX models: standard (Grand Sport Rally or “GSR” in some markets), RS (Rally Sport), SE (Special Edition) and MR (Mitsubishi Racing) varied slightly in their performance capabilities. Subtleties unique to each model accounted for variations in acceleration, handling and top speed.

The IX MR retained the features of the Evolution VIII MR, like Bilstein shocks, a 6-speed manual transmission, a rooftop vortex generator, BBS forged wheels, HID xenon headlights, foglights, accessory gauge package, “zero lift” kit, special badging and an aluminum roof. All models continued to sport Recaro bucket seats, Brembo brakes and Momo steering wheels. Additional revisions from 2005 included a closer gear ratio for the 5-speed manual transmission, new lighter Enkei wheels on non-MR models, a redesigned front end with a more efficient air dam (the most noticeable feature are the two small oval ducts to cool the intercooler pipes), and a new rear bumper with a diffuser undersurface to smooth out the airflow coming out of the car for non-US models.

The US versions of the Lancer Evolution IX did not come with the AYC but the ACD was still present. The drivers can select from three different driving modes, “Tarmac” “Gravel” and “Snow”, and the car’s computer system relatively promotes the active center differential to change the differential locking which, eventually changes the front/rear power distribution to increase traction, thus providing an optimum driving experience. Although the US versions did not come with the AYC, it did come with a rear 1.5way clutch type LSD (limited slip differential)which, limits the slip from both rear wheels causing less traction loss of the rear wheels. The most common setup is the 1.5 way LSD, locking on throttle and partially locking on braking. In racing, Lancer Evolutions are not equipped with AYC or ACD because it is believed that better lap times are achieved by pure driver skill without any computer based assistance systems.

One of the changes from the previous iteration of the Lancer Evolution, was the change in the engine, the new 4G63 came with MIVEC, Mitsubishi’s variable valve lifting technology, which drastically improves the fuel consumption by changing the valve timing on the intake cam. The MIVEC system is similar to Honda’s i-VTEC system only that it doesn’t change valve lift, only intake valve timing.

Three trims were available for Japan, Asia and Europe. Although all models used the same 291 PS (214 kW; 287 hp) engine, the torque differed from one model to another. In Europe, however, the Evolution IX was advertised to have 280 PS (206 kW; 276 hp). The GSR produced 400 N·m (295 lb·ft) of torque, while the RS and GT produced 407 N·m (300 lb·ft).

The BMW S85 is Beautifully Engineered

Very possibly the highest output N/A road-going engine BMW will ever make.

The S85B50 is a high-revving engine designed to utilize power from a wide rev band. Having a redline of 8250 rpm, it achieves over 100 bhp (70 kW)/litre which is an incredible feat for a naturally aspirated production engine, as other manufacturers have used supercharging or turbocharging to reach a similar output level. The S85 features a very high compression ratio of 12.0:1, exceeding the previous S54’s ratio of 11.5:1

  • 5.0 Litre V10 engine, 90 degree bank angle, 507 hp (378 kW) @ 7750rpm/520 N·m (384 lb·ft) torque @ 6100rpm
  • Cast aluminum block with bed plate design split at the crankshaft axis.
  • Cast aluminum heads with four valves per cylinder and CNC machined ports and combustion chambers. Valves are actuated through non-rotating inverted bucked cam followers.
  • Oil-cooled, forged aluminum pistons from Mahle Motorsport
  • Forged steel crankshaft with counterweights, shared crankpins producing an uneven firing interval of 90 or 54 degrees.
  • Double VANOS system which varies both intake and exhaust cam phasing
  • 10 individual electronically controlled throttle butterflies
  • Knock sensors have been eliminated by utilizing the “ionic current” measuring system. Using the ionic current system, engine misfires as well as knock can be measured simultaneously. The ionic current is measured by passing a low voltage across the spark plugs immediately following the ignition spark.
  • Quasi-dry sump lubricating system
  • The firing order for the S85 engine is 1-6-5-10-2-7-3-8-4-9.
