Volvo S80 Gasoline Turbo I6

Although one could argue that other auto manufacturers share Volvo’s dedication to safety and functionality, it would be difficult to find many examples that are backed up by a  ransversely mounted in-line six-cylinder engine. While isolated cases of transversely mounted 16 engines do exist-Daewoo’s Magnus engine, for example-they are rather uncommon. Volvo achieved the 16 engine’s transverse orientation by streamlining the entire installation-engine, transmission, and ancillaries-into as compact a space as possible, and relocating all ancillaries except the alternator to the unused space above the gearbox. Ancillaries are still belt-driven, but overhead camshafts are now chain-driven. Both the chain and the belt are driven by gears at the rear end of the crankshaft, with the gears partially integrated into the engine block. The drive system is integrated into a small gearbox with an intermediate shaft inside the driveshaft. Different gears drive the two shafts, delivering one speed for the camshaft drive and a different speed for the ancillaries. The alternator, installed on the engine block, is directly driven off the same shaft that drives the ancillary belt. The crankshaft damper has also been moved inside the engine block, located at the front of the crankshaft.

To help the S80 meet the conflicting demands of fuel economy, environmental responsibility, and performance, the 16 incorporates cam profile switching, continuous variable valve timing, and a variable intake system. For performanceoriented drivers, an optional4.4-LV8 with all-wheel drive was also offered. Now, Volvo has expanded its options for satisfying those conflicting needs with the introduction of a slightly smaller, turbocharged six-cylinder engine. Modeled after the naturally aspirated 16, the new 3.0-L T6 engine uses the 16 block and cylinder head with different machining, manifolds, and other boltons. The new port-fuel-injected all-aluminum engine has a mass of 419 lb (190 kg) as shipped and 468lb (212.5 kg) as installed. As with any turbocharger, exhaust gases leaving the cylinders spin a turbine on the end of the turbo shaft, causing an impeller at the other end to force compressed air into the induction system.The compressed air effectively increases the
amount of oxygen available in the engine for the combustion process. The boost pressure is controlled by a traditional
wastegate on the compressor side. On the intake side, an electronically controlled dump valve helps reduce the ‘whoosh’
noise when the throttle is released, and allows for more precise boost control.

With twin-scroll technology, the T6 engine’s exhaust gases are divided into two outflows, half from three cylinders and half from the other three cylinders. An air-to-air intercooler helps improve volumetric efficiency through isochoric cooling. With the twin-scroll turbo, the T6 delivers strong low-end torque without the size, complexity, or cost of a large engine displacement or two separate turbochargers. With the addition of turbocharging, Volvo was able to downsize the new engine’s
displacement by 7.5% as compared to the normally aspirated 16. With bore and stroke measurements of 3.23 in (82 mm) and 3.67 in (93.2 mm), respecaei-tively, the T6’s bore-stroke ratio, 0.880, is nearly the same as the 16’s 0.875. The longer stroke, which makes both six-cylinder engines slightly undersquare, helps generate better low-end torque and better overall fuel efficiency. Turbocharged to 0.7 bar (10.1 psi), the T6 delivers 281 hp (210 kW) and 295 lb·ft (400 N·m), the latter over a wide range from 1500 to 4800 rpm. Specific power rating is 73.5 hp/L (54.8 kWIL) and the specific torque is 99.9 Ib ·ft/L (135.5 N·m/L). Introduced with the 2008 S80, the new 3.0-L turbocharged T6 is expected to be offered in other Volvo models in 2009.

The S80 also boasts of three firsts for passenger cars. The first was the use of a built-in, fully integrated GSM phone, complete with both a hands free function and a lift-up hand-set. The second was the fitment of the straight six engine in a transverse mounting. Volvo claims to be the first manufacturer to succeed in mass producing this configuration. No existing manual gearbox would fit in the engine bay with the six cylinder engine, so Volvo had to develop their own, claimed to be the world’s smallest manual gearbox, the M65. The previous record holder was also a Volvo gearbox, the M56 developed to fit the wide 5 cylinder transverse engine first used in the 850 series cars. Thirdly, the S80 was the world’s first car with an environmental specification, covering aspects such as those directly relating to the car such as allergens from textiles and fuel economy and the life cycle of the car from production to dismantling.

For Volvo, the S80 was a major step forward into the age of modern car design, particularly with the use of multiplex wiring.

The S80 was initially available with four different engines. Starting the range was a detuned 2.4-litre 140 hp 5-cylinder. This was also available as a CNG and as an LPG version. The fully tuned version produced 170 PS (125 kW). Next up was a 2.9 L 196 PS (144 kw) 6-cylinder, then 272 PS (200 kW) T6 and finally, the 140 PS (102 kW) 2.5 L TDI (diesel). The 2.9 has a Straight-6 engine while the T6 was powered by a destroked twin-turbocharged version. In 2000 there was the addition of the 200 hp (149 kw) 2.5T, available with standard all-wheel drive. The 2.5T model featured a light-pressure turbocharger. Late 2001 introduced the 163 PS (120 kW) 5 cylinder common rail diesel D5, detuned to 130 PS (96 kW) and sold as 2.4D in some markets.

On January 31, 2006, Volvo unveiled the first pictures of the second generation S80. Generally all features of the car were upgraded substantially. The new S80 will feature a new 3.2 L straight-6 or 4.4 L V8 engine in combination with available four-wheel drive. The second-generation S80 is the first Volvo sedan model to become available with Volvo’s compact, transversely fitted V8 with a power output of 316 PS (232 kw) and 440 N•m of torque. With four catalytic converters and advanced electronics, this engine, which was first introduced in the Volvo XC90, is one of the cleanest V8s on the market. The exterior is similar to that of the first generation but is greatly improved with more high strength boron steel in the body for safety. The interior is seen as one of the most comfortable in the automotive industry. The layout of all items is well placed and the HVAC control panel on the waterfall center console is superb. This second generation S80 is no exception to Volvo’s on going improvements and inventions of safety. The second generation S80 has been give the IIHS 2007 Top Safety Pick Award in overall safety protection. Also again in November the IIHS awarded the 2008 Volvo S80 with Top Safety Award. This S80 performed outstanding above its German and Japanese rivals. Score perfect scores for frontal, side, and rear impacts. The car was unveiled at the Geneva Motor Show on February 28, and sales began on June 2006. The new S80 is based on the Volvo P24- platform which was mainly developed by Volvo itself, also used for vehicles including Ford’s S-MAX and Galaxy large MPVs.[9] Even although some of these other Ford vehicles ride on this platform, the majority of the cars’ parts was made by Volvo alone and not found in the Ford.

Volvo’s Personal Car Communicator (PCC) remote control will also be an optional feature with the new S80. This feature is fairly new to the automotive industry. Before a driver gets to their car, they are able to review the security level and know whether they have set the alarm and if the car is locked. Additionally, there is a heartbeat sensor that warns if someone is hiding inside the car.

The all new S80 is the first Volvo model to feature Adaptive cruise control (ACC) with Collision Warning and Brake Support (CWBS). Adaptive cruise control helps ensure comfort and relaxed driving by letting the driver select the desired speed and the minimum time gap to the vehicle in front of them. When a radar sensor detects a slower vehicle in front of them, Adaptive Cruise Control adapts to that vehicle by applying the brakes as necessary. As the Collision Warning System senses an impending collision, it alerts with a flashing light on the windshield and an audible alarm. Meanwhile Brake Support offers additional assistance by preparing the braking system so that the car can begin stopping faster and avoid a potentially dangerous situation before it happens. Volvo S80 is also available with a new safety innovation called Blind Spot Information System (BLIS, first seen in Volvo S40) which senses when a person enters the drivers blind spot and Active Bi-Xenon Lights (ABL) to illuminate around curves in the dark. Volvo is known for making historic strides in the production of intuitive new safety systems. BLIS system has been recently introduced at Mercedes-Benz higher specifications cars,nearly two years after Volvo.[10] The second generation Volvo S80 is much more luxurious than the previous generation, and it flaunts its “Scandinavian Luxury” design language. It competes directly against the Saab 9-5, Lexus GS, BMW 5 Series, Mercedes Benz E-Class, Audi A6, and Acura RL. The second generation S80 has already won awards in best mid size luxury sedan interior.
