Turbo engine versus naturally aspirated engine: supercharged sports cars

Friedrich Nitzschke, ex-boss of BMW M GmbH, predicted it:' A You can't get past turbo today . 'And so here we are today. BMW M no longer has a single naturally aspirated engine in its range.

But the Munich-based manufacturer is not the only manufacturer that is now using turbocharged engines - we all have sports cars rummaged out, which in their latest version rely on the turbo, and previously had a freely breathing unit under the hood.

Porsche 911 (991) Facelift

Somehow it was clear, but true Nobody wants it: Even Porsche has to attach a turbocharger to its six-cylinder boxer engines. At least with the 'mass' models like the 911 Carrera and Carrera S. With the facelift, they get a three-liter boxer with an exhaust gas turbocharger. The 911 does not have to accept any loss of performance, the Carrera then makes 370, the S version 420 hp. Whether or how things will continue with the 911 GTS seems open. According to vague rumors, an injection to 450 hp is not considered unlikely.

Much more important: the response. Can the engineers in Zuffenhausen be able to maintain the deep connection between the gas pedal and the engine? At least once, we've ridden a Turbo Carrera. The experiences of our editor Yoshi Kimura read here . The lifted turbo 911 will be presented at the IAA in autumn 2015. Exciting.

VW Golf R32 /R

The Golf VI R develops 20 hp more than the R32, i.e. 270 hp. The very latest model of the seventh generation has around 300 hp from the world-famous 2.0 TFSI of the EA888 family. In the supertest, this generation can finallyalso convince in terms of time and weight. Only in terms of sound maybe not quite like the charismatic but boozy VR6 unit.

Honda Civic Type-R

Good, the new Civic Type-R is not yet available from us, but will come to the dealer halls in the course of 2015. Its predecessor relied on a naturally aspirated engine with a displacement of two liters and 201 hp and wanted to make life a little more difficult for the VW Golf GTI. However, he remained below expectations ; the engine of the ex-endurance tester by sport auto was sluggish and thirstier than any Bavarian at the Oktoberfest.

The upcoming version relies on the compression of the intake air with the help of a turbocharger. Unlike its predecessors, this Civic Type-R no longer has the Golf GTI on its list of competitors. With 310 hp he immediately attacks the Golf R, which also rolls to the start-finish line in Hockenheim with a two-liter turbo engine.

BMW M3 /M4

With the last BMW M3, the last free-breathing high-performance engine also retired. The V8 named S65B40 in the E9X series was the only eight-cylinder that the legendary athlete from Garching near Munich was ever allowed to carry under the hood. Before that it was either a four-cylinder in the original M3 (E30) or a straight-six in the E36 and E46 series.

M GmbH is returning to the six-cylinder with the F8X series (three and four). With one difference: the three-liter unit with engine code S55B30 is force-ventilated by two turbochargers. 431 hp are in the data sheet, ten more than the predecessor. In addition, the M3 and M4 motors weigh a maximum of 550 Nm on the crankshaft, which is 150 more than the M3 of the previous generation.

BMW M5 /M6

When the vehicle was stationary, it somehow sounded like diesel, it clacked and nailed to itself. But when the BMW E60 M5 (or E63 M6) really got going, the ten-cylinder engine started trumpeting like a Formula 1 engine. No wonder: The S85B50 adopted technologies and know-how from Formula 1; BMW was still active there when the M5 of the E6X series appeared. The five-liter V10 with 507 hp is considered to be one of the most legendary engines from Garching, precisely because it was not forcibly ventilated, and exhibited extremely spontaneous responsiveness and enormous revving. And it sounds worlds better than the new V8.

The latest BMW M5 (generation F10) and its coupé brother, the M6, use a 4.4-liter twin-turbo V8, the S63B44. Its power output: up to 600 hp in the BMW special model '30 Years of the M5'. Above all, the turbo engine puts 680 Nm on the crankshaft in series production and consumes a good 20 percent less.

Mercedes-AMG 63 series

Mercedes cannot say goodbye to its legendary 6.3 designation, although the new model no longer deserves it. The old M The 156 engine had 'only' 6.2 liters displacement and performed its service in all classes, including the SLS, the E-Class, and of course the C-Class. Those days are over.

The new engine in the AMG C-Class comes from the GT super sports car and has a displacement of just four liters, a shrinking cure of 2.2 liters. The four-liter biturbo unit was renamed M 178 DE 40 AL baptized. It produces either 462 HP in the normal version of the AMG GT, as well as 476 HP in the C63 without S. The respective S models have 510 HP.

Larger sedans like the E63, CLS63 or S63 use the same engine in principle, but in the large sedans it has 5.5 liters of displacement - and more power, namely up to 585 hp.

It continues on since e 2, below, the head of development at Lamborghini explains how he intends to continue to rely on naturally aspirated engines.
