Bugatti plan new 1500 hp Hybrid with axial flux motor & electric turbos

Autocar report that a new Bugatti Veyron is currently undergoing initial conceptual engineering tests in a programme aimed at unveiling the car in 2016 prior to a planned start to customer deliveries the following year. According to sources close to Bugatti, early test 
mules for the new car exist 
and have already been 
pressed into action in an 
early round of testing.

“Five developmental prototypes with differing powertrain combinations have been constructed up to now,” said one insider. “They are based on the existing car 
but use various solutions 
that are being considered for the new model.”

Following recent arrivals such as the McLaren P1, Porsche 918 Spyder and LaFerrari, the new Bugatti will feature a battery powered hybrid electric powertrain. The same quad-turbocharged 8.0-litre W16 powerplant as 
its predecessor will be retained but with the possible addition of electric turbochargers, perhaps along the lines of those used by Porsche in LMP1 (Porsche and Bugatti are both part of the VW group) and the 2014 Formula One KERS MGU-H (where the H stands for heat).

The big news centres around plans to provide the new Bugatti with hybrid drive by way of a disc-shaped Axial Flux electric motor mounted within the gearbox housing. Together, the petrol engine and electric motor are said to deliver up to 1500 hp. By comparison, the Veyron Super Sport has 1183 hp.

Autocar sources suggest that torque will be capped at 1500 Nm for the sake of gearbox reliability. A Veyron Super Sport already has 1500 Nm from 3000 to 5000 rpm. With an Axial Flux AC Induction motor able to generate almost as much torque (1250 Nm from the EE in-wheel motor) The Bugatti hybrid electric powertrain design looks like a very conservative step with full potential limited by the fragility of it's mechanical driveline.

The new hybrid Veyron should have some fairly startling performance in electric only mode (if it has one - see LaFerrari), but in parallel mode, other than providing torque fill below 3,000 rpm, (partly explaining why Bugatti expect 0-100 km/h times to drop to 2.3 sec) the full potential of the hybrid powerplant will be restricted by a mechanical transmission layout that may not have moved on much from the current Veyron.

As with the McLaren P1, a hybrid that still idles in traffic, or the LaFerrari which has no pure EV mode, the new Bugatti may succeed in combined the superior low rpm torque characteristics of an electric motor to give the instant throttle response and acceleration of an EV, what McLaren call 'torque fill', with the enormous top end torque of a large displacement forced induction ICE, but in common with the aforementioned hybrid hypercars, it will be very much a first generation mild hybrid.

We will have to wait for future evolutions of hybrid supercar powertrain design before we see anything truly revolutionary.

Next Generation Volt to debut at 2015 @ Detroit Auto Show

The next generation Chevrolet Volt will debut at the 2015 North American International Auto Show in Detroit, Global Chevrolet Chief Marketing Officer Tim Mahoney said today.

The 2016 Volt will build on the award-winning original's strong foundation of technology innovation. Volt sales were up 13 percent in July and more than 65,000 have been sold since it was introduced – making it the best-selling plug-in passenger car in the U.S. market.

"Volt is the perfect example of the ingenuity that drives everything we do at Chevrolet," Mahoney said at the Center for Automotive Research Management Briefings. "Volt fully delivers on the promises of Find New Roads and will continue to provide consumers with the transportation solutions they need and deserve in the future."

Volt owners are driving more than 63 percent of their overall miles in electric vehicle mode, collectively logging more than 500 million gas-free miles since the Volt's retail debut in 2010. That has saved more than 25 million gallons of gasoline.

While the driving range in EV mode can be affected by temperature, driving technique and terrain, the ease with which Volt drivers are avoiding gasoline use demonstrates the Volt's suitability for almost any lifestyle.

Volt owners who charge regularly typically drive more than 970 miles between fill-ups and visit the gas station less than once a month.

The Volt has received multiple customer satisfaction awards from leading third-parties. According to a recent leading independent satisfaction survey, the Volt is the highest-rated compact car under $55,000. Owners are showing their satisfaction as well. For the past three years, a leading customer publication has reported survey results showing more than 90 percent of Volt owners said they would definitely buy a Volt again.

The Volt continues to draw buyers from non-General Motors' products. In the 2013 calendar year, nearly seven of 10 new Volt buyers traded in a non-GM vehicle, the majority of which were Toyota Priuses.

Among its accolades, the 2014 Volt has been recognized for its safety, most recently receiving the Insurance Institute for Highway Safety 2014 Top Safety Pick+ designation for vehicles equipped with an available Forward Collision Alert system.

Audi’s first plug-in hybrid – A3 Sportback e-tron – now on sale in EU

The first plug-in hybrid from Audi, the A3 Sportback e-tron, is now available to order for customers in Europe. Approximately 410 Audi dealers in Europe – including no fewer than 105 in Germany – are selling the A3 e-tron at a basic price of 37,900 euros on the German market. An individual installation check, the “e-tron plus” special package and “green” power from Audi complete the offering for the Audi A3 Sportback e-tron. The compact electric car will be handed over to its first customers this winter.

“For Audi, the A3 Sportback e-tron marks another important step toward sustainable individual mobility,” states Wayne Griffiths, Head of Sales Germany at AUDI AG. “Our dealers have had an entirely positive response to the A3 Sportback e-tron, which shows that the combination of efficient drive technology and a sustainable energy source is really what the market is looking for.”

The Audi A3 Sportback e-tron brings together a 1.4 TFSI gasoline engine and an electric motor, giving the compact automobile a system output of 150 kW (204 hp). The A3 Sportback e-tron’s fuel consumption in accordance with the NEDC standard for plug-in hybrid vehicles is just 1.5 liters of fuel per 100 kilometers (156.8 US mpg), with CO2 emissions of 35 grams per kilometer (56.3 g/mi). Under electric power alone it has a range of 50 kilometers (31.1 mi), and over 900 kilometers (559.2 mi) in combined mode. The basic price for the Audi A3 e-tron in Germany is 37,900 euros. Audi is also offering attractive leasing conditions: 319 euros per month with a term of 36 months.

In Germany, the plug-in hybrid will be sold by 105 selected e-tron dealers; across Europe approximately 410 dealerships will sell the model. Their employees are receiving special training in sales and service relating to electric vehicles. Between mid-July and the end of August, Audi is providing training to around 2,000 sales, service and used car employees from all over Europe at its Training Center next to Munich. In addition, some 300 German high-voltage technicians and service advisors from Audi will undertake a technical training course at the Service Training Center in Neckarsulm.

In future, every e-tron dealer will also have at least one charging station that e-tron customers can use, even after their purchase. The Audi A3 Sportback e-tron can be charged quickly via a charging point at the dealership, within the public charging infrastructure or at the customer’s home. For the latter option, Audi offers – in Germany – an individual installation service whereby a technician checks the electrics in the customer’s home, makes any adjustments that may be required and installs the charging dock, which is designed for safe, convenient charging.

To ensure that sustainability is not compromised during the at-home charging process, customers in Germany can switch to environmentally friendly electricity, known as Audi energy. With Audi energy, the A3 Sportback e-tron is totally emission-free when operated electrically. All electricity all comes from hydroelectric power stations in Germany, Austria and Switzerland. To mark the start of the A3 Sportback e-tron, Audi has additionally put together the attractive “e-tron plus” package. In Germany it includes the charging dock, a cable for public charging points, MMI navigation plus, Audi connect and phone box.

GKN to use F1 technology to improve fuel efficiency of London buses

GKN plc and The Go-Ahead Group have agreed a deal that will help reduce emissions in cities with the supply of electric flywheel systems to 500 buses over the next two years.

The innovative GKN system is based on Formula One race technology developed in the UK. It will help increase the efficiency of every bus to which it is fitted by using less fuel and therefore reducing carbon emissions. This same technology helped Audi’s R18 e-tron win at Le Mans last month.

Go-Ahead has placed an order for GKN Hybrid Power to supply 500 of its Gyrodrive systems to the transport operator. The Gyrodrive system uses a high speed flywheel made of carbon fibre to store the energy generated by a bus as it slows down to stop. It then uses the stored energy to power an electric motor which helps accelerate the bus back up to speed, generating fuel savings of more than 20% at a significantly lower cost than battery hybrid alternatives.

The agreement covers the supply of the complete Gyrodrive system, including the innovative GKN Hybrid Power flywheel as well as GKN’s advanced EVO electric motor, a GKN designed and manufactured gearbox, and installation. The system is designed to last for the life of the bus eliminating the need for any battery changes.

Following successful trials on buses in London, Go-Ahead intends to utilise the technology in cities it serves across the UK, initially in London and Oxford.

Philip Swash, CEO GKN Land Systems, said: ‘This is an important milestone for GKN Hybrid Power. We’ve worked in close partnership with Go-Ahead throughout the development of this innovative technology and it’s very exciting to move into the production phase.

The fact that we are using the same groundbreaking technology that helped Audi win at Le Mans for the past three years to improve fuel efficiency in the public transport sector also shows what great innovation there is in the UK’s engineering sector.’ CEO of Go-Ahead, David Brown, added: ’Our collaboration with GKN has been a most constructive one. We have a strong record in continually reducing our carbon emissions and flywheel technology will help us make buses an even more environmentally responsible choice and encourage more people to travel by public transport.

The flywheel technology helps us to reduce our fuel consumption and C02 emissions so improving air quality for all those living, working and visiting the city.’

GKN Hybrid Power is based in Oxfordshire, with final assembly taking place in a new facility at GKN’s site in Telford. The Gyrodrive technology is being further developed for other mass transit markets including trams, construction and agricultural equipment. Earlier this year GKN announced the acquisition of Williams Hybrid Power from Williams Grand Prix Engineering Limited to form GKN Hybrid Power, which is focused on delivering complete hybrid solutions across multiple vehicle, power and industrial markets.

Audi may move to 4MJ Hybrid class for 2015 WEC

Audi looks certain to continue racing its Le Mans 24 Hours-winning R18 e-tron quattro LMP1 with only one hybrid system in next year's World Endurance Championship.

Audi Sport boss Wolfgang Ullrich told AUTOSPORT that no major changes to the concept of the R18 turbodiesel were planned in the development drive to increase the LMP1 car's level of energy retrieval for 2015.

Asked if that meant there would be no second system to supplement the 2014 R18's front-axle braking retrieval system, he said: "We will try to do what is possible in a short period of time.

"We must be more competitive, but we must be reliable. There will not be big concept steps.

"We will try to have a little bit more hybrid power: we have talked ideas of what we can do on the basis of this car."

The R18 runs in the two-megajoule P1 sub-class, whereas rivals Toyota and Porsche, which respectively have second rear-axle and exhaust-driven systems, are entered in the 6MJ division.

Ullrich's comments suggest that Audi is trying to at least move up one class to the 4MJ category.

Audi abandoned a second, Formula 1-style turbo-driven retrieval system ahead of the start of the season.

Ullrich said that the sale of Williams Hybrid Power, which developed its flywheel energy-storage system, to global engineering group GKN in April would not affect its LMP1 programme.

"We will get support at least at the level we had before, so we are not concerned," he explained.

"The existing flywheel technology is not at its limit."

The GKN flywheel used by Audi has a maximum storage capacity of 1.2 MJ of energy while the supercapacitor used by Toyota can store up to 6 MJ.

BMW i9 Supercar to launch in 2016

Auto Motor und Sport is reporting on a future BMW i9 due to launch in 2016. In the same very year, BMW is celebrating 100 years.

BMW i9 would be based off the i8 hybrid sports car with more power and a beefier appearance. Still featuring a plug-in hybrid, the BMW i9 is said to forgo the 1.5 liter three-cylinder engine in favor for a larger one and with more power.

Furthermore, the i9 would also get a bigger electric battery which will generate more than the 131 hp found in the i8.

Lightweight materials and construction remain top priorities for BMW so if it comes to life, expect the i9 to feature even more carbon fiber and aluminum parts. The i9 will retain the perfect 50:50 weight distribution.

From 0 to 100km/h, the BMW i9 is rumored to run in under 4 seconds and with a top speed above 155 mph.

Toyota Supra, BMW Z4 sports cars to share platform

Toyota Motor and BMW will develop a common platform for two sports car models that will become the first products to come out of a comprehensive tie-up the two inked in January 2013.

The automakers will use the same platform as early as 2017 for the BMW Z4 and a planned revival of the Toyota Supra, a model popular in the 1980s and 1990s. The vehicles will have different body designs and be sold under their respective brands.

The car will have a front-engined direct-injection four cylinder turbo and electric motors driving all four wheels. The supercapacitor system will be derived from technology first seen in Toyota's Hybrid Supra HV-R in 2007 when it won the Tokachi 24 hour race and more recenly Toyota's Le Mans LMP1 race cars.

BMW will supply the 2.0 liter turbocharged engine combined with electric motors produced by BMW at its engine plant in Munich while a Toyota-developed electronics system is expected to provide torque-vectoring capability.

The partners also plan to discuss joint manufacturing and parts procurement. BMW is a leader in building cars with lightweight carbon fiber bodies, but the technology is expensive, leading many to focus on whether Toyota will adopt it.

Toyota's tie-up with BMW is aimed at making use of the German carmaker's luxury-vehicle expertise while lowering costs. Toyota and BMW also jointly work on research for lithium-air battery expected to be more powerful than the lithium-ion batteries used in many hybrid and electric vehicles,
