Bi-Turbo – Automobiles Review

K.MAN Audi R8 V8 Bi-Turbo GTK, GTK S and GTK RS

Chiptrick has unveiled their latest project based on Audi R8 4.2 liter V8. The name of the project is K.MAN and it is available in three powerful versions – GTK, GTK S and GTK RS. There are also some styling improvements as well.

Stage I – GTK – boosts the engine to 590HP (434 kW), which is an increase of 170HP compared to factory’s power. The GTK weighs just 1,680 kg (3,704 lbs), so it has a power-to-weight ratio of 2.85 kg/HP.

Stage II – GTK S – offers 640HP (471 kW), a power boost of 220HP. The power-to-weight ratio is 2.64 kg/HP.

Stage III – GTK RS – has whopping 750HP (551 kW), an increase of 330HP. The power-to-weight ratio is impressive 2.27 kg/HP.

No words about acceleration 0-100 km/h, but it is around 3.0 seconds. Still, Chiptrick revealed information for 0-200 km/h times – GTK 11.9 seconds; GTK S 11.4 seconds and GTK RS 10.6 seconds.

Other highlights include Club sport chassis frame and a reinforced brake system for the top-of-range GTK RS. There is also a manual gearbox for all performance stages.

Optionally, K.MAN also has a wide range of carbon and GFK parts for those who prefer a little extravagance, and this allows K.MAN to offer individual identities from “cautiously different” up until the radical “DTM looks”.

GAD Mercedes-Benz CLS 63 AMG V8 Bi-Turbo

German based tuning company – GAD has released some pictures and information about their latest project based on Mercedes-Benz CLS 63 AMG.

The CLS 63 AMG is powered by a 5.5 liter direct-injected V8 with 518HP (381 kW) and 700Nm (516 lb-ft). It is connected to a 7-speed MCT (multi-clutch technology) sport gearbox. If fitted with the AMG Performance Package, the performance is improved to 550HP (405 kW) and 800Nm (590 lb-ft).

Obviously this is not enough, that’s why GAD boosted the mighty Bi-turbo V8 to whopping 803HP (590 kW) and 1149Nm (847 lb-ft) of torque.

The results are thanks to a pair of new bigger turbochargers, a new custom exhaust manifold with downpipe and sport catalyst, bigger intercoolers, updated fuel and ignition systems and finally attentive settings.

Audi’s Electric Bi-turbo Engine

Audi will produce a super high-efficient electric bi-turbo diesel engine. In this future technology, a secondary compressor boosts the main turbocharger at lower engine speeds.

Audi has announced they are testing an electric bi-turbo diesel engine.

The latest bi-turbo diesel from Audi is the 3.0 Bi-TDI. It develops 313HP (230 kW) and 650Nm (480 lb-ft) at just 1450RPM. This is a specific power output of 106HP (78 kW) per liter displacement. However, its combined fuel consumption in the A6 is only 6.4 / 100 km (36.75 US mpg) and CO2 emissions of 169 g/km.

What all turbocharged engines have in common is that the turbocharger is driven by energy from the exhaust. This means that starting from very low revs, the rise in boost pressure and therefore torque becomes gradually greater only as the exhaust energy increases.

A new development stage is the electric biturbo. This makes it possible – independently of the exhaust energy available – to build up charge pressure quickly and achieve high levels of torque even at very low revs.

In advanced diesel development at Audi’s site in Neckarsulm, a 3.0 V6 TDI was built and calibrated with an electric biturbo. It is a combination of a conventional gas-driven turbocharger with a secondary electrically driven compressor – whose exterior appearance is almost identical to that of a conventional turbocharger.

Instead of a turbine wheel driven by the exhaust gas stream, this is an auxiliary charging stage arranged in line with the gas-driven turbocharger. It integrates a small electric motor that can accelerate its turbine to very high speeds in an extremely short time. The electrically driven compressor is placed after the main turbocharger and intercooler in the charge air path. In most operating states, the charge air is routed around it via a bypass. However, when the flap integrated in the bypass closes – i.e. when the main turbocharger’s energy output is low – the air is directed into the electric compressor and is compressed there a second time.

The results of the new concept are impressive. Torque buildup occurs significantly earlier in every drive-off, which the driver perceives as a distinct boost in performance.

The energy required to drive the electric compressor is largely offset by battery regeneration during coasting phases, so that the end effect is essentially neutrall with regard to energy consumption.

The flexible and compact charge air path enables two-stage turbocharging with just one turbine that is driven by exhaust gas. The reduced heat demand enables earlier activation of the catalytic converter.

2012 BMW Alpina B6 Bi-Turbo

Alpina has announced 2012 B6 Bi-Turbo featuring all-aluminium V8 power plant with two turbochargers delivering stunning amount of power.

2012 Alpina B6 Bi-Turbo has a twin-turbo 4.4 liter V8 with 540PS (397 kW) at 5500RPM and 700Nm (516 lb-ft) of torque at just 3000RPM. Two turbo-chargers configured in parallel, each feeding one of the two cylinder banks, with specially developed large diameter exhaust-turbines allow this engine configuration to provide both exceptional power output and an abundance of torque over an especially broad rpm range while maintaining excellent throttle response at low rpm.

High-performance MAHLE pistons are designed specifically to deal with temperatures and pressures associated with up to 1.0 bar charging and the engine’s 9.2:1 nominal compression ratio. Altogether this results in an impressive specific output of 122.7hp (90kW) per litre and a mean total compression of 20.1 bar. Direct injection and Double-VANOS contribute to the B6 Bi-Turbo’s class-leading consumption and emission figures: 10.5 l/100km and 244 g/km CO2, Combined cycle, measured according to ECE Norm.

The performance is simply astonishing – 0 to 100 km/h in 4.4 seconds, which is exactly the same as the latest M5 F10 and a top speed of 320 km/h.

The engine is mated to SWITCH-TRONIC 8-speed Sport Automatic Transmission by ZF. It offers Sport Shift Mode (S) and Manual Shift Mode (M).

The suspension comes with specific springs, increased front wheel camber and a subtle adjustment of the toe-in in conjunction with a 20″ wheel-tyre combination all serve to produce a very agile chassis set-up. The lightweight 20″ Alpina CLASSIC wheels, with MICHELIN PILOT SUPER SPORT tyres in the dimensions 255/35 ZR20 front and 285/30 ZR20 rear, contribute significantly to the direct handling and precise steering. Conventional tyres are used to promote ride comfort. There are also Drive Performance Control (electronically adjustable dampers) and Dynamic Drive (active roll stabilization) as standard.

The exterior boasts aerodynamics body kit including a new front spoiler with carbon fiber splitter and a rear spoiler with a rear wing, which is available as an option. All these components also ensure the effective flow of air to various cooler groups, such as the inter-coolers and engine cooling system. One special detail: the high-performance brakes, with a diameter of 374mm front and 345mm rear, are additionally supplied with cooling air by a specially constructed NACA air intake on the front underbody.

The interior comes with blue Alpina instruments with high resolution information display with black panel LCD technology. There are also a sport steering wheel, hand-stitched in LAVALINA leather, blue illuminated entry sills with logo and classic Alpina myrtle wood.

The B6 Bi-Turbo features an extensive range of standard equipment, including leather upholstery, fully adjustable comfort seats with heating system, navigation system with preparation for Bluetooth mobile phone, USB audio interface, Xenon lights and LED fog lights.

BMW Alpina D5 Bi-Turbo

Alpina has introduced one more vehicle – D5 Bi-Turbo based on 535d. It comes with one of the most powerful diesel engines in the world.

In other words – 350PS (257 kW) coming from a 3.0 liter twin-turbo straight-six diesel, which has the same fuel-economy rating as the 530d with 245PS (180 kW) – 6.2 liters per 100 km on combined cycle. Not bad for such amount of power, not bad at all! 0 to 100 km/h in just 5.2 seconds and a top speed of 270 km/h (168 mph). That is the reason why 535d is called ///M diesel.

The mighty engine is mated to the new ZF SWITCH-TRONIC 8-speed Sport Automatic gearbox. It is further improved to handle all new torque.

The stance is improved by adding a set of lowering springs. There are also a set of 20” Alpina alloy wheels fitted with Michelin Pilot Super Sport tires in dimensions – 255/35 ZR20 at the front and 285/30 ZR20 at the rear.
