Nitschke hints at an M-tuned three-cylinder engine

BMW M GmbH boss Friedrich Nitschke has revealed the current generation M3 is effectively sold out.

Speaking to Car & Driver, Nitschke said the M3 Coupe and Convertible will remain in production for approximately six more months but all the cars are spoken for.

The executive also hinted that future engines will be closely related to BMW's units but they will continue to be "optimized for the specific needs of M customers."

Nitschke downplayed the possibility of all-wheel drive variants by suggesting they would be too much of a compromise because of the added weight and loss of steering precision. The executive also feels that anyone who wants a high-performance all-wheel drive BMW can just order an X5 M or an X6 M.

 

When asked about BMW's new three-cylinder engine, Nitschke sounded optimistic about offering a high-performance variant. As he explained, "The three-cylinder is an attractive engine. It is possible to reach around 185 to 200 horsepower (137- 149 kW) per liter in a forced-induction three-cylinder and we have 1.5 liters of displacement." This means the a M-tuned three-cylinder engine could have an output in excess of 310 HP (231 kW).

Referitor la ce a promis seful VW, la cate probleme sunt cu TSI-urile (de 1.2 in special), parca nu m-as arunca la prima generatie :-).

Volkswagen Chairman confirms 10-speed DSG, high-performance diesel engine

Volkswagen Chairman Prof. Dr. Martin Winterkorn has revealed some new details about the company's future product lineup.

Speaking at the Vienna Motor Symposium, Winterkorn confirmed the company is working on a high-performance diesel engine that will produce 136 HP (100 kW) per liter. The executive also acknowledged the development of a 10-speed dual-clutch transmission that will offer improved fuel efficiency.

There's no word on when they will arrive, but the executive also discussed plans to refine their petrol and diesel engines. As he explained, “Since the year 2000, we’ve reduced the fuel consumption of our TDI and TSI engines by more than 30 percent. I’m convinced that by 2020 we can achieve further increases in efficiency of around 15 percent."

Winterkorn also see natural gas engines playing a larger role in future products because the "technology is fully developed" and CNG vehicles are "environmentally friendly, economical and suitable for everyday use."

Lastly, the executive confirmed plans to "electrify all vehicle classes" to improve fuel efficiency. In the short term, Volkswagen will focus on plug-in hybrid technology. The Audi A3 e-tron and Porsche Panamera E-Hybrid will go on sale shortly and be followed by plug-in hybrid variants of the Golf, Passat, Audi A6 and Porsche Cayenne.

Bine ca n-o fac manuala in 10 trepte.

Eram curios cum le organizau. Si cum conduceai cu o astfel de manuala. Cred ca pt mamaligari era ideala.

[alexx_elf]

Sa nu vorbesc prostii, dar nu cumva Relu si Forrester au avut 10 trepte pe impreza aspirata?

[Relu]

Reductor + cutie in 5 trepte nu inseamna 10 trepte

E ca si cum ai zice ca masina ta are 8 roti, daca le numeri si p-alea de iarna ....

[ska]

porsche are deja cu 7trepte manuala

cea de la vw va fi in genul :

[adrian_r5]

E ca si cum ai zice ca masina ta are 8 roti

Toate masinile au 8 roti: 2 in fata, 2 in spate, 2 in stinga si 2 in dreapta

 

PS - unele mai au si roata de rezerva

[mecea]

apai daca numeri asa poti ajunge si la 12 > plus patru pe jos.

Pai cum functioneaza de fapt? Eu aveam impresia ca, atunci cand ai reductorul cuplat, turatia motorului nu mai intra 1:1 in cutia de viteze ci cu un alt raport, fiind acelasi efect in final ca si cum ai avea 2 x 5 viteze .

 

PS: Mult simplificat, mi se pare ca ar fi ca la bicicleta, unde reductorul ar fi doua din cele trei foi, iar cutia de viteze, pinioanele.

La masini nu e ca la bicicleta, in sensul ca "foile" sunt la iesire .....

[mecea]

In loc sa-i zici ce NU ESTE mai bine ii explici CE ESTE ... nu ? Dar asta ar insemna sa o faci in contra naturii tale si sa te rebootezi ?

Pentru tine sunt sigur ca ai fost, intreaba pe restu ca sa te lamuresti insa.

alio, si mergeau cat tineau calificarile.

[Forester]

Chiar daca le fac si "fiabile", mai trebuie totusi si fie si "drivable", ca o masina care se taraie agonizant pana pleaca de pe loc dupa care sapa transee cand atinge 4000 de ture este total inutila.

Mult mai buna mi s-ar fi parut o directie de cercetare pentru a gasi o solutie de reducere a consumului la motoarele mari, pentru ca orice s-ar zice, mult mai bine si mai usor se conduce asa ceva.

Facelift la Duster in toamna, la salon. In afara de plansa bord/consola centrala si mici modificari la interior, va avea si un nou look frontal, in linie cu Logan/Sandero.
