The Alpina B5 was introduced at the 2017 Geneva Motor Show in all-wheel drive only Saloon and Touring variants. The B5 features a 4.4-litre N63M30 V8 engine that generates a maximum power output of 447 kW (599 hp) and 800 N?m (590 lb?ft) of torque. Based on the N63B44O2 V8, it has uprated pistons, new twin-scroll Garrett turbochargers and new spark plugs by NGK. The B5 can accelerate from 0?100 km/h (0?62 mph) 3.5 seconds with a top speed of 330 km/h (205 mph), making it the fastest estate car currently in production. pagani wallpapers, lamborghini wallpaper, lexus wallpapers, BMW 5 Series G30 wallpapers, toyota wallpapers
(Porsche 911)Carrera 3.2 (1984?1989)
The replacement for the SC series came in 1984 as the 911 3.2 Carrera, reviving the Carrera name for the first time since 1977. This was the last iteration in the original 911 series, with all subsequent models featuring new body styling and new brake, electronic, and suspension technologies.
A new higher-displacement engine, a 3.2-litre horizontally opposed flat 6-cylinder unit, was utilized. At the time Porsche claimed it was 80% new. The new swept volume of 3,164 cc was achieved using the 95 mm (3.7 in) bore (from the previous SC model) combined with the 1978 Turbo 3.3 crankshaft’s 74.4 mm (2.9 in) stroke. In addition, higher domed pistons increased the compression ratio from 9.8 to 10.3:1 (9.5:1 for the US market). New inlet manifold and exhaust systems were fitted. The 915 transmission was carried over from the SC series for the first three model years. In 1987, the Carrera got a new five-speed gearbox sourced from Getrag, model number G50 with proven BorgWarner synchronizers. This slightly heavier version also featured a hydraulically operated clutch.
With the new engine, power was increased to 207 hp (154 kW; 210 PS) (at 5,900 rpm) for North American-delivered cars and to 237 PS (174 kW; 234 hp) (at 5,900 rpm) for most other markets. This version of the 911 accelerated 0?97 km/h (0?60 mph) in 5.4 seconds and had a top speed of 240 km/h (150 mph) as measured by Autocar. Factory figures were more modest: 0?60 mph time of 6.3 seconds for the US version and 6.1 seconds for cars outside the American market.
The brake discs were increased in size to aid in more effective heat dissipation and improved oil-fed chain tensioners were fitted to the engine. To improve oil cooling, a finned cooler replaced the serpentine lines in the front passenger fender well. This was further improved in 1987, with the addition of a thermostatically controlled fan.
