BMW Z3 V12
in autocarBMW has lifted the veil of secrecy on a wild V12-powered version of the first-generation Z3.
The experimental prototype, created by BMW’s research and development division, was built as an engineering exercise with the aim, in the words of one BMW source, “to see how far we could stretch the concept”.
No firm details on the one-off Z3 have been forthcoming, although it is thought to run BMW’s M73 engine. Used in the earlier 750i and 850Ci, the big V12 boasted a capacity of 5.4 litres and kicked out 321bhp and 361lb ft of torque.
By comparison, the most powerful first-generation Z3 model, the Z3 M Roadster, used the 3.2-litre straight six from the M3 with 321bhp and 261lb ft.
Parece que o V12 foi posto dentro do Z3 para "demonstrar" que qualquer que seja o tamanho de um motor, este cabe num roadster. A única vez que ele foi testado foi pela revista Autozeitung. Como já referido, o carro tinha uma potência de 322 cv (o Z3 M debitava 321 cv) e 490 Nm (o Z3 M tinha 353 Nm) de binário máximo às 3900 rpm. A caixa é manual e tem 6 velocidades.
De acordo com a publicação alemã, o carro faz 0-100 km/h em 5.5 segundos, conseguindo percorrer a distância de 1000 metros em 24.4 segundos. A sua velocidade máxima é de 263 km/h.
As jantes do carro são de 17". Os pneus têm as seguintes medidas: 225/45 à frente e 245/40 atrás. O carro tem um peso de 1400 kg.
Scans da revista:After breaking the photo story on the BMW M division's one-off, V12-powered Z3 prototype earlier this week, we can now share with you some interesting details surrounding its creation, though as you will soon find out, we may need the help of our German speaking readers.
We'll get straight to the point and let you know what Matthew Russell, Product and Technology Communications Manager for BMW North America, told Carscoop about the Z3 M V12 after he did some digging of his own:
"The car was built in 1999 and was the proof that all engine sizes of the time fit in the roadster," said Russell. "It was shown only once: in August 1999 to the German car magazine Autozeitung."
As we rightly assumed, the ultimate M model of the Z3 roadster series borrowed BMW's M73 5.4-liter V12 engine from the E38 750i/iL sedans and E38 850Ci coupe of the mid-1990s to early 2000s.
The 12-cylinder engine was rated at 322hp (326PS) at 5,000 rpm and 490Nm (361 lb·ft) at 3,900 rpm, and was linked to a 6-speed manual gearbox driving the rear wheels.
According to the 1999 article from Autozeitung, the Z3 M V12 was capable of accelerating from standstill to 100km/h (62mph) in 5.5 seconds, to 1,000m (0.62 miles) in 24.4 seconds, and reach a top speed of 263 km/h (163mph).
By comparison, the production Z3 M Roadster model sported an M3-sourced 3.2-liter naturally aspirated straight-six delivering 321hp (325PS) and 353 Nm (261 lb·ft) in EU specification.
We also learn that the Z3 M Roadster V12 was fitted with 17-inch wheels in 225/45 tires up front and 245/40 at the back and that it tipped the scales at a hefty 1,400kg (3,086 pounds).
As mentioned in the beginning of our story, we’d appreciate it if any of our German-speaking readers could provide a translation of the main points mentioned in the magazine article.
Alguns leitores do Carscoop traduziram alguma coisa, como eu não percebo de alemão, não sei se estão correctos:
Fonte: CarscoopAutoZeitung mentions that they drove it on a BMW testcourse near Munich during a solar eclipse on August 11th 1999. It was a rainy day so they had to stopp snapping or driving the car several times.
They say that the project was commissioned by Dr. Gerhard Schmidt, the head of drivetrain development to compare different engine configurations and just to see if it was possible at all!
It took 3 engineers about 3 month to convert an arctic blue M Roadster into this orange beast.
They took the gearbox from a 850 ci
They had to modify the radiator, oilpump, oilpan, the exaust manifold, some other details and stiffened the springrates.
The car rather wants to go sideways through turns which doesn't make sense but sure is a lot of fun!
It has wheelspin from first through third gear and the engine produces 400Nm. already at 1000 rpm.

É um facto que os despistes de Bmw são quase sempre piso molhado, álias como quem trabalha em seguradoras sabe muito bem.
Cump.
A ideia de colocar um V12 num roadster "compacto" como o Z3 é tão absurda como genial.
O carro em si não ganha em nada, em números consegue quase igualar o L6 do Z3m.
A BMW ainda hoje anda à procura da super-potencia...
Devo precisar de oftálmicas novas, mas colocar um v12 num Z3 não me parece feito nenhum. O compartimento do motor é grande q.b. para acomodar um motor desse tamanho...dinamicamente é outra história (provavelmente um aborto com 4 rodas).
Era mais "divertido" de ler se fosse com o novo 125i, mesmo na versão de 3p.
Entre certezas e alguns rumores, aqui fica o calendário dos futuros produtos da BMW.
Roadmap: BMW future products
With Paris Motor Show upon us and the BMW rumormill churning more than ever, we wanted to take the time and look at future BMW products that we might see in the upcoming years. Some of the models we discussed below are set in stone and with a market launch date already set, but there are plenty others that fall under the “Rumor” category and scarce details are known about them.
The assumptions we’re making below are based on information from our own sources as well as using common sense and industry knowledge.
BMW 1 Series / 2 Series
In 2013, BMW will unveil the coupe and convertible variants of the redesigned 1 Series. The two models will be sold under the 2 Series moniker and will make their way into the U.S. market.
Next month, we will see BMW’s first attempt at the front-wheel drive market with the introduction of the 1 Series GT. In 2015, rumors say that BMW will launch a 1 Series sedan in the United States to compete with compact sedans planned by German competitors. The rear-wheel drive 1 Series Sedan will compete against offerings from Audi, the A3 which comes in 2014, and Mercedes-Benz CLA launching next year.
BMW 3 Series
With the sedan and sports touring launch, the 3 Series family has two more models to welcome:ActiveHybrid 3 and 3 Series GT. The BMW ActiveHybrid 3 made its North American debut at the 2012 Detroit Auto Show. In early 2013, BMW will bring to market the first hybrid version of the popular 3 Series model.
BMW 3 Series GT Rendering
Internally the 3GT is referred as the “Progressive Activity Coupe”, the 3 Series GT will come to market in March 2013 as one of the BMW insiders say, “the alternative to alternatives, a style conscious car with the dynamic prowess to match its looks.”
BMW 4 Series
A new family of BMW products will be born next year. The coupe and convertible variants of the 3 Series will be sold under a new badge: 4 Series. The new 4 Series Coupe will allow BMW to price the vehicle slightly higher to compete directly with offerings from Audi (A5) and Mercedes-Benz (smaller SLS). The new coupe goes on sale in late summer 2013, and the convertible debuts in late 2013.
Unconfirmed yet highly rumored, a 4 Series Gran Coupe may appear in 2014.
BMW 5 Series
Pretty quiet here over the next few years. We will see a life cycle impulse in 2013, but no new models are planned. The “ugly duck” 5 Series GT will also get a facelift next year.
BMW 6 Series
The 6 Series family is almost complete as well. We have seen the introduction of the coupe and convertible models, and this year the Gran Coupe joined the luxurious family.
BMW 7 Series
The LCI comes to market this fall and will bring not only a slightly refreshed design, but also a wide variety of technology updates. On. e of the biggest exterior changes comes from the front where now the flagship 7er gets “squarish” LED corona lights with an LED turn signal indicator placed in the headlight. Each headlight contains 8 LEDs. While the previous model featured a kidney grille with 9 and 12 slats, based on the Night Vision Camera option, the facelifted 7 comes now with a single configuration of 9 slats.
The flagship model will be redesigned in 2016 and move from an all-steel to a carbon and aluminum body.
BMW Z4
Based on the recent spy photos, we can deduct that the changes for the Z4 LCI are minor, mostly around the headlights, taillights, side mirrors and gills. The lights will feature brighter daytime running lights with white corona rings and the illuminated eyebrow at the top of the light unit. The side mirrors will also house the signal indicators, despite missing from the recent spy photos.
BMW Z2
We’ve been speculating on a small roadster since 2009, at times even offering a launch date in 2012, but over the past year, the Z2 rumors have started to slowly die out. The long-rumored BMW Z2 project is still alive and according to our sources, the small roadster could use the UKL platform, the front-wheel drive drivetrain that will underpin the next generation MINI, and which debuts next month.
Continuação.
BMW X3Another facelift in 2014 will be the one for the X3 midsize crossover. A high-seller in the U.S. and around the world, the X3 LCI is expected to follow the design lines of newer models.
BMW X4
BMW is preparing to launch a new X-model: BMW X4. The entry-level Sports Activity Coupe is set to launch in 2014 and will be manufactured at the Spartanburg Plant in South Carolina.
Built under the code F26, the X4 shares the same platform as the new X3, and will be positioned, price wise, below the X5.
BMW X5
The third-generation BMW X5 will launch in late 2014 and is based on the architecture of the 5 Series which provides significant contribution to weight reduction. The F15 X5 will feature more flowing character lines and sculpted surfaces that will broaden the design of the X family giving it a more stocky and dynamic look.
BMW X6
The X6 Sports Activity Coupe receives a facelift this year and a new design in 2015.
BMW X7
The large SAV project was canceled in 2008 when BMW decided to focus its attention on EfficientDynamics. But a recent report, from the usual BMW insider Scott27, says that the Munich-based automaker is reconsidering the X7. The car would be BMW’s ultra luxury SAV challenger in the high-end luxury market where demand continues to grow.
BMW Minivan and other FWD products
Without a doubt BMW sees their next growth potential in the front-wheel drive market. As we mentioned earlier, 1 Series front-wheel drive will soon come to market, followed by other FWD products, including a small minivan.
BMW i3 and i8
Another big bet for the Bavarians is the i sub-brand. The electrified family of bimmers will first launch to market two products: a fully electric city car dubbed i3, and an interpretation of a hybrid sportscar, i8. The i3 hits the market in late 2013, followed in 2014 by the i8. Rumored i1 and i5 models are also part of the long-term plan, but no final decision has been made at the moment.
BMW sports car in collaboration with Toyota
This past June, BMW and Toyota announced a partnership to develop architecture and components for a sports vehicle. The two automakers refrained from sharing further details on the cars and a timeline, but the expectations are to see a green sportscar in the next 5 to 7 years.
BMW M3
Coming to market in 2014, the F80 M3 will be powered by an inline-six engine. The engine of choice is a newly developed 3.2 liter unit that is rated at 450 horsepower. The F80 M3 will debut in concept form at the 2013 Geneva Motor Show, while the production version, will appear in September 2013 at the Frankfurt Auto Show.
BMW M4
F82 M4 Coupe basis its design on new 4 Series Coupe and it will differentiate itself from the 3 Series family through a sleeker front apron and slightly redesigned headlights. The super sporty coupe will come to market in 2015.
BMW M6 Gran Coupe
The four-door M version of the M6 will also come to market in 2013. M6 Gran Coupe builds atop the recently launched 6 Series Gran Coupe and will replace the M5 and M6 at the top of the M family. The power will come from the same engine as the new M5 and M6, a high revving 560 hp M TwinPower Turbo V8 mated to a high torque 7-speed M-Double Clutch transmission (M-DCT).
BMW M7 or M770i xDrive
Rumors around a flagship M7 have been going around for years and a recent report byTheDetroitBueaubrought back the idea of a high-end M car. But other news outlets say BMW plans to introduce a high-performance 7 Series, labeled M700i xDrive, and heading to the U.S. in 2015.
The 7 Series M Performance Automobile will likely feature the V8 Twin-Turbo 4.0 liter engine producing around 475 hp and 480 lb-ft of torque. While the M770i xDrive is geared towards customers asking for a high-performance and sporty 7 Series, the M-like car will be underpowered when compared to the V12 760Li which outputs 570 horsepower and 665 lb-ft of torque.
The Holy Grail – BMW Supercar
Yes, that supercar that every BMW fan is hoping and waiting for. Tons of rumors around a potential high-power BMW but none of those rumors have proven so far to be sustainable. We did learn in the past that the M Division has already built an M Supercar, but the business case never received the approval stamp from BMW board. More recently we heard that the M folks are back at entertaining the idea of a high-end, super fast and sporty car, but the project is still a few years out.
Will it be called M1, M8 or who knows what other name, time will only tell…
As you can see, the next decade is quite important for BMW and the company aims to cover most, if not all of the premium segments.
Muita ambição. Mal posso esperar para ver alguns desses projectos.

Por acaso foram buscar umas linhas à Ferrari e à Mclaren:
Este "moço" deve ser baratinho de manter...
Não são bem 25 anos... são mais.
O V12 é um projecto dos anos setenta, só que devido à crise petrolífera ficou adiado até 1987 no 750i.
BMW Announces New 1.5-Liter Turbo'd 3-Cylinder Petrol and Diesel Engines with up to 222HP - Carscoop
BMW Announces New 1.5-Liter Turbo'd 3-Cylinder Petrol and Diesel Engines with up to 222HP
In 2007, BMW introduced the Efficient Dynamics strategy to its new vehicles, which encompasses fuel efficient petrol and diesel engines, highly efficient transmissions, “intelligent” management of ancillary systems and advanced aerodynamics.Despite investing heavily on hybrid and EV technology, as is evident with the ActiveHybrid models and the new “i” sub-brand, BMW also believes that the internal combustion engine has potential for improvement and will continue to power the bulk of its existing and future models.
To that end, it is introducing a new lineup of 1.5-liter three-cylinder TwinPower turbocharged engines in both gasoline and diesel forms.
The new engine family can be mounted longitudinally or transversely and features an aluminum block, double Vanos infinitely variable camshaft control, Valvetronic variable valve timing, direct injection (common rail on the diesels) and depending on the model, one, two or three turbochargers.
The design principles are basically common for all of BMW's in-line units, with optimized cylinder modules, each featuring a displacement of 500 cc each.
Thus, the three-cylinder has a 1.5-liter capacity, the four-cylinder is a 2.0-liter and the six-cylinder is 3.0-liters. Moreover, the power developed in each cylinder is between 30 and 55 kW (40-74 HP) and torque from 60 to 80 Nm (44-59 lb-ft) for the petrol engines and 20-45 kW (27-60 HP) and 75-110 Nm (55-81 lb-ft) for the diesel units.
Engines of the same fuel type share 60 percent of their parts, whereas petrol and diesel engines have a 40 percent parts commonality.
The new member of TwinPower family is the 1.5-liter three-cylinder unit. According to the figures provided, the petrol versions will deliver between 120 and 222 HP and 180-240 Nm (133-177 lb-ft) of peak torque, while the diesels will be rated between 80HP and 180 HP and 225-330 Nm (165-243 lb-ft) of torque.
BMW claims that the 1.5-liter TwinPower Turbo engines are extremely fuel efficient and provide high low-end torque and rapid response. It adds that the “half of a six-cylinder” unit is free of first-and second-order inertial forces while roll torque, much smaller than the six-cylinder, is eliminated by the use of balancer shaft.
According to the carmaker, the addition of a torsional vibration damper results in a "remarkably smoothly-running engine", while it also points out that it will sound good.
"Because the frequency of the sound of a three-cylinder engine increases 50 percent faster than that of a four-cylinder, the engine is perceived as being extremely vivacious and sporty," said BMW in a statement.
The new 1.5-liter turbocharged engine is expected to power the next-generation of the Minifamily that’s due in 2014, and the BMW i8 hybrid supercar, the next 1-Series and possibly at some point, the 3-Series as well.

Nova família de motores da BMW...com o 3 cilindros !
A base da nova família de motores é um princípio de construção comum para a linha de unidades. O mecanismo básico é constituído por módulos de cilindros optimizados, com uma capacidade de 500 cc cada, desenvolvidos para o topo do rendimento termodinâmico ...e para utilização num veículo de passageiros. Por conseguinte, o novo motor de três cilindros tem uma capacidade de 1,5 litros, a unidade de quatro cilindros é de 2,0 litros e o de seis cilindros é de 3,0 litros. A potência desenvolvida de cada cilindro situa-se entre 30 e 55 kW (at 60 - 80 Nm), no caso de o motor a gasolina, e no motor a gasóleo desenvolve entre 20 e 45 kW (de 75-110 Nm).
As semelhanças estruturais entre o bloco a gasolina e a diesel, incluem a distância entre os cilindros, o bloco de alumínio, o desenho do eixo de equilíbrio, o arranjo da cadeia de tempo, a disposição dos parafusos da cabeça do cilindro e o revestimento de alta qualidade nas superfícies do cilindro de perfuração. Em geral, o número de peças idênticas utilizadas em motores equipados com o mesmo tipo de combustível sobe para 60 por cento, enquanto que o nível de semelhanças estruturais entre a gasolina e diesel é de cerca de 40%. Ainda mais benefícios são fornecidos por interfaces padronizadas. Além dos pontos de montagem de motores idênticos, trata-se principalmente as interfaces para o circuito de arrefecimento, os colectores de admissão e de escape e os sistemas de aquecimento e ar condicionado. Em comparação com os modelos actuais, o número de combinações possíveis nestas áreas diminuiu para cerca de metade. Finalmente, todas as unidades de alimentação têm a mesma injecção de ar e o mesmo lado de escape. É por isso que o três e quatro cilindros dessa nova família são adequados para uma arquitectura longitudinal e transversal de montagem, pelo que num futuro próximo, serão utilizados em modelos BMW e MINI.
