2004 Volvo XC90 V8 All Wheel Drive Specs and Review

XC90 is present in the automotive market by carrying the strength of the V8 under the hood by increasing performance on the tarmac and sharpening Volvo’s competitive advantage in the tough SUV segment.

In the United States, an average of around 30 percent of all SUVs sold in the premium segment have a V8 engine. This means that the Volvo XC90 five and six cylinder versions have only exploited 70 percent of the market potential so far. But it still achieves great success.

To maintain overall performance, all supporting units such as alternators are installed directly into the engine itself. The starter motor is mounted above the transmission for the same reason.

What’s more, the exhaust camshafts are driven by a secondary chain that runs the camshaft inlet, saving additional space.

The left cylinder enclosure is offset by a half cylinder in front of the right bank, contrary to normal practice in the automotive world – so the engine can slot neatly into the XC90 structural beam network and thus increase impact safety.

The result is a V8 that is only 754 mm long and 635 mm wide – the most compact on the market compared to an equivalent volume engine.

As a result of this compact dimension and the fact that the beam head and cylinder head are made of aluminum, the new Volvo V8 only weighs 190 kg – an important consideration when targeting low fuel consumption.

The new engine from Volvo is the cleanest V8 gasoline on the market today. It meets American ULEV II (Ultra Low Emission Vehicle, stage II) – which has not been managed by other V8 gasoline.

ULEV II has been fulfilled with help:

  • Four catalytic converters. Two of them are type Close Coupled Catalyst and each is mounted on one exhaust manifold. The other two are placed under the floor of the car.
  • Higher idling speeds on cold starts, around 1250 r / min, and ignition optimized for faster engine heating on cold starts and catalytic converters
  • Lean air / fuel mixture for lower emissions at cold start

The result is very low emissions before the catalytic converter is activated – which occurs only 15 to 20 seconds after the engine is turned on.

The 4-valve engine also features variable inlet and exhaust valve timing (CVVT). This system adjusts the valve opening time so that it matches the current rotation and engine load conditions. Thus, the engine is used more efficiently, reduces fuel consumption, reduces emissions, and improves performance

The Volvo XC90 V8 produces 315 horsepower and torque – the most important characteristic of the V8 engine – is 440 Nm on a massive 3,900 r / min. And at the most driven rides, around 2000 r / min, torque not less than 370 Nm is available for the driver.

To increase low-end torque, the Volvo V8 has a valve in the inlet manifold that closes below 3,200 rpm. In this mode the air flow between two cylindrical edges is broken, which creates a wider and more evenly distributed torque curve.

Acceleration from 0 to 100 km / h requires 7.3 seconds and fuel consumption is 13.3 liters / 100 km (5-seat). The highest speed is limited to 210 km / h (190 km / h in the US).

Engine notes are an important detail for buyers of V8-powered cars, and this is something Volvo Cars noticed during the development of new engines. In hunting for the V8 characteristics rumble, it is the position of the inlet manifold which is the main determining factor.

Excellent safety and environmental properties add a healthy measure of extra spices to the V8 market where buyers often base their choices on emotional arguments such as driving pleasure, energy – and even engine sound.

In the world of V8 development, engine sound is its own science. Traditional American V8s have loud offbeat growls, while Europeans like a little smoother, more sporty rumble.

Volvo Cars plans to sell 15,000 Volvo XC90 V8s a year, with 75 percent of the total production going to North America.

The US is without the largest V8 market comparison, followed by Canada and Mexico. Germany finished fourth and Japan fifth.

Sales will begin in the US in early 2005, after which the Volvo XC90 V8 will be introduced gradually in other markets.

The Volvo XC90 has been a tremendous sales success for Volvo Cars. The original production volume of 50,000 cars per year has increased in a row, and since spring 2004, annual XC90 production at the company’s Torslanda plant in Sweden has been raised to 90,000.

What’s more, the Volvo XC90 has received more international awards in a shorter period of time than other Volvo.
