Yesterday we are ending the test of the Volkswagen Passat 2.0 TDI BiT, 240-BHP of power. The engine of 2.0 liters develops a specific power of 120 HP/litre, sensational if we take into account that we are talking about a engine turbo. Although it may seem so, is not the diesel engine is more “tight” market. We have decided to collect in this list cars, a diesel with the highest specific power of the time. And for years we thought that a simple 1.9 TDI 150 CV was an engine “tight”. That we came over…
1) BMW 3.0 turbodiesel with three turbos. 381 HP, 127 HP/liter.
This engine is a marvel of engineering, that with the help of three turbochargers – two of them of variable geometry – get extract of their 2.997 cubic centimeters of displacement that is nothing less than 381 HP of power. Your engine torque is 740 Nm, available between 2,000 rpm and 3,000 rpm. Mounts in the BMW X5 M50d, BMW X6 M50d and BMW M550d, three vehicles signed by BMW M Performance Automobiles. Impresses its elasticity in the power delivery, and a court’s power located in nothing less than 5400rpm.
2) Volkswagen 2.0 TDI BiT. 240 HP, 120 HP/liter.
Has been the protagonist of the last test motor, mounted on a Volkswagen Passat. Thanks to a system of double turbocharging in series, this engine develops 240 HP with a huge pressure blowing of 3.8 bars. Its torque is 500 Nm, and allows a Passat do the 0 to 100 km/h in just 6.1 seconds. To support such a specific power, its internal components have been developed ad-hoc and you have a cylinder head different from the rest of the 2.0 TDI. It will also be available in the new Volkswagen Tiguan.
3) Volvo 2.0 PowerPulse. 235 HP, 117,5 HP/liter.
The new family of engines Drive-E, Volvo is modular, and share the architecture of four cylinders and two litres of petrol. The latest innovation, which will hit the market with the launch of the new Volvo S90, is the 2.0 PowerPulse, which develops 235 BHP of power thanks to an ingenious system of compressed air, which drastically reduces the delay in the turbocharger inlet. Currently we are already selling versions of 224 HP, this 2.0 turbo, with a specific power to the more moderate, of 112 CV/liter.
4) BMW 2.0 TwinPower Turbo. 231 CV, 115,5 HP/liter.
BMW manufactures diesel engines of four cylinders sensational. I was able to test a BMW X1 and a BMW 420d, both equipped with a 2.0 TwinPower Turbo 190 HP, and combine excellent great performance with a consumption of laughter. The diesel four-cylinder most powerful BMW develops 231 HP, thanks to a turbocharger twin-scroll and double-entry. maximum torque of 450 Nm is consistent between 1,500 rpm and 3,000 rpm. By the time it is offered exclusively mounted in the BMW X1 xDrive25d, from the 44.400€.
5) Audi 3.0 V6 TDI twin-turbo. 340 HP, 113,3 CV/litre.
The Audi SQ5 TDI competition and other Audi high-performance have a version of 326 HP from this same engine.
The V6 engines Audi TDI have been mounted in all kinds of applications, but its more powerful version is exclusive preserve of the Audi SQ5 with TDI motor in these moments. In particular the Audi SQ5 TDI plus, whose propeller develops 340 HP, thanks to the help of two turbochargers in series. Your engine torque is 700 Nm between 1,400 rpm and 2,800 rpm. A gigantic torque that allows you to reduce the 0 to 100 km/h in 0.1 seconds behind the Audi SQ5 TDI competition: now he does it in 5.1 seconds.
6) Audi 4.0 V8 TDI. 435 HP, 108,7 HP/liter.
Of the Audi SQ7 TDI we have already discussed at length. Your engine is a marvel of technique, but not for its high specific power, but for being the first production car to employ turbo-electric. It has three turbochargers, one of which is electric and has a lag zero. This new V8 turbo 4.0-liter develops in addition to a gigantic maximum torque: 900 Nm of torque from just 1,000 rpm, constant up to the 3.250 rpm. Also impressive that accelerates the two-ton SUV to 100 km/h in 4.8 seconds.
7) BMW 3.0 TwinPower Turbo. 320 HP, 106,6 HP/liter.
There is a 3.0 twin-turbo 313-HP source BMW, but it is an older engine, this TwinPower replaces. For simplified versions are not what I have picked up.
After the 127 HP per liter from its big brother, the 320 HP and 106,6 HP per liter of the 3.0 TwinPower Turbo diesel BMW does not impress so much. However, it is a propeller that has been recently launched in the new 7 Series from BMW – we can not forget your partial build in carbon fiber – and stands out by a motor torque very high (680 Nm between 1,750 rpm and 2.250 rpm) with consumption approved to seem of laughter: 5.3 l/100 km for a luxury sedan more than 5 meters long and nearly two tons of weight.
8) Ford 2.0 TDCi Bi-Turbo. 210 HP, 105 HP/liter.
A member that we cannot forget in this family of high specific power is the propeller 2.0 TDCi twin turbo Ford. Its origins are the alliance of engines between Ford and the PSA Group, but Ford has continued to evolve on their own this engine, while PSA has abandoned the high-power applications. We have tested it in the new Ford Edge, and with a specific power of 105 CV/litre surprised by his thrust strong and high torque: 450 Nm between 2,000 rpm and to 2,250 rpm.
We wanted to limit the list to eight thrusters for the sake of simplicity. Below 105 CV/litre, the offer is triggered. Without going any further, we have the 3.0 SDV6 Jaguar/Land Rover (306 HP) or the 2.0 TDI BMT Volkswagen (204 HP) – both with 102 BHP/litre, and if we reduce the filter to 100 HP a liter, the new 1.6 CDTI Opel, 1.6 i-DTEC from Honda and 1.6-litre dCi Renault. They all have identical power outputs of 160 HP and a specific power of 100 HP per liter. But one thing is clear: we have only begun.
The downsizing comes from the hand of specific powers that just 10 years ago seemed unattainable.
Mercedes will launch soon versions of the 240 HP of your new OM 654 of two liters, and when Volvo put on sale the new S90 in just a few months, it will come with a diesel engine of 235 HP under the arm. And of course, BMW is cooking up a new super diesel of six cylinders, three litres and four turbos, whose power could reach the 450 HP according to evil tongues. Where is the limit? Let’s discuss in the comments section. Oh, and if you lack a motor, decídnoslo and we will correct it.
