GKN develops two-speed eAxle; in production on BMW i8
November 10, 2014
GKN has developed the first two-speed eAxle; the technology has entered production on the BMW i8 plug-in hybrid sports car, (earlier post) in which it provides power to the front wheels from a 96 kW, 250 N·m (184 lb-ft) electric motor. (A 170 kW/231 hp three-cylinder combustion engine in the BMW i8 drives the rear wheels.)
Production electric and axle-split hybrid vehicles have used single-speed transmissions; however, GKN said, using a fixed ratio limits electric drives in terms of either acceleration or top speed as they must disconnect at certain speeds to prevent the motor overspinning. GKN said its two-speed eAxle is the first in series production to enable the electric drive to boost the vehicle’s performance across its entire speed range.
New Unipiston clutch piston technology in series production; enables better fuel economy
November 06, 2014
Federal-Mogul Powertrain’s new high-modulus injection-molded Unipiston clutch pistons are now in series production at the company’s facility in Chivasso, Italy. The technology was a 2013 Automotive News PACE Award Winner in the process category.
Unipiston is a one-piece, rubber-to-metal bonded piston that hydraulically engages clutches to activate the gearshift. The compact one-piece design reduces the number of leak paths while improving reliability and simplifying assembly, and allows transmission designers more flexibility, including increased clutch apply pressures, higher rotational clutch speeds, and larger diameter clutches. This flexibility enables transmissions with additional clutches to be packaged in a smaller space, while providing improved fuel economy, reduced emissions and enhanced vehicle performance.
Volkswagen begins production of latest-gen DSG at new plant in China; 1.2M unit capacity by 2016
November 05, 2014
Volkswagen started production of the latest generation of its advanced dual-clutch gearbox (DSG), the DQ380, at its new Tianjin components plant in North China. Initially, the new Volkswagen plant will have an annual production capacity of 450,000 units, which will be increased to 1.2 million units by 2016. Volkswagen has invested about €265 million (US$332 million) in the first stage of the plant.
The dual-clutch gearboxes produced especially for the Chinese market will be used in several Group models in China in the future. With the DQ380 gearbox in combination with the third generation of the new EA888 engine, which is produced at the engine plants in Changchun and Shanghai, Volkswagen will achieve a consumption reduction of 0.5 l/100 km and therefore a CO2 reduction of 12 g/km compared with the previous generation.
GM Warren Transmission Plant to build electric drive unit for second-gen Volt; part of $300M investment in Michigan through end of year
October 28, 2014
Later today at the Detroit Economic Club, General Motors CEO Mary Barra will confirm that its Warren Transmission Plant will build the new electric drive unit—the GM Voltec 4ET50 Multi-Mode EDU—for the upcoming second-generation Chevrolet Volt. As a result, most major Volt powertrain components—from the battery cells to the new 1.5-liter range-extending engine—will be made in Michigan, establishing the state as the company’s global engineering center of excellence for vehicle electrification. The new Volt will debut at the North American International Auto Show in Detroit in January 2015.
The drive unit for the first-generation Volt consists of two motors—a 111 kW main traction and 63 kW (at 4800 rpm) generator motor (55 kW generator output)—as well as three clutches and a planetary gear set tucked in the end of the traction motor that improve overall efficiency by reducing the combined rotational speed of the electric motors as needed. (Earlier post.) GM will subsequently be providing details of the second-generation drive unit.
Visio.M researchers develop lightweight torque vectoring transmission for EVs; improved regen, better dynamics
October 15, 2014
|The lightweight torque vectoring transmission is applied in a Visio.M test vehicle. Click to enlarge.|
As part of the Visio.M project in Germany, researchers at the Technische Universität München (TUM), along with their colleagues in the consortium, have developed a lightweight torque vectoring transmission with characteristics that are optimally adapted to electric vehicles. The engineers at the Gear Research Center (FZG) at TUM focused on recouping as much braking energy as possible with the goal of enhancing the range of the vehicle.
Whereas drive torque conventionally is distributed evenly to the wheels of the drive axle, a torque vectoring system allocates torque between the wheels as required, noted FZG engineer Philipp Gwinner. This provides particularly good drive dynamics. As an example, when a vehicle accelerates in a curve, greater torque is applied to the outside wheel. The car steers itself into the curve. The result: greater agility and, at the same time, safer road handling.
EPA annual trends report finds new vehicle fuel economy at record 24.1 mpg; new powertrain technologies rapidly gaining share
October 10, 2014
EPA released the latest edition of its annual report on trends in CO2 emissions, fuel economy and powertrain technology for new personal vehicles in the US. Among the top-level findings was that Model year 2013 vehicles achieved an average of 24.1 mpg (9.76 l/100 km)—a 0.5 mpg increase over the previous year and an increase of nearly 5 mpg since 2004. Fuel economy has now increased in eight of the last nine years; average carbon dioxide emissions are also at a record low of 369 g/mile in model year 2013. The majority of the carbon and oil savings from current vehicles is due to new gasoline vehicle technologies, the report observed.
The report, “Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 Through 2014”, also found that the light truck market share increased slightly in MY 2013, after several years of volatility; that the vehicle weight trend is flat and vehicle power trend is increasing more slowly; that many new powertrain technologies are rapidly gaining market share; and that consumers have an increasing number of high fuel economy/low CO2 vehicle choices.
GKN develops all-wheel drive disconnect system for A-, B-, C-segments; fuel economy improvement up to 4%
October 07, 2014
GKN has developed the first Disconnect All-Wheel Drive System for A-, B- and C-segment vehicle platforms. The innovative disconnect function enables vehicles to combine the enhanced traction, dynamics and stability of all-wheel drive with improved on-highway fuel efficiency.
The system responds to driver inputs and road conditions, connecting and disengaging drive to the rear axle on demand. By eliminating rotating losses from the driveline, during steady state cruising fuel efficiency can be improved by up to 4% compared to permanent all-wheel drive systems.

|Rendering of friction plate. Click to enlarge.|
BorgWarner is supplying its high-performance wet friction technology for Volkswagen Group’s DQ 400e dual-clutch transmission (earlier post)—the Group’s main near-term gearbox for all hybrid and plug-in hybrid applications that are transverse. (Earlier post.) Current examples include the Golf GTE and Audi A3 e-tron.
This core transmission for hybrid vehicles with transversely mounted engines employs three clutches—two drive clutches (K1/K2) plus an engine-disconnect clutch (K0). An 80 kW, 330 N·m (243 lb-ft) three-phase permanently excited synchronous machine is located in the hybrid module on the input shaft, between the engine-disconnect clutch K0 and the drive clutches (K1/K2).
Chevy’s Cruze Diesel: a compact diesel contender in the US
September 08, 2014
|The Cruze Diesel is identified by a discreet badge on the trunk. Click to enlarge.|
US buyers hunting for a non-premium diesel passenger car (i.e., not a truck or SUV, and not a vehicle from BMW, Audi, Porsche or Mercedes-Benz) have until recently only had Volkswagen-brand cars as an option: Beetle, Golf, Jetta, Passat. Accordingly, Volkswagen of America (VoA) diesel sales to date in 2014 represent slightly north of 23% of all Volkswagen of America sales. In August, Jetta posted 3,988 diesels sales (26% of Jetta sales, while Passat TDI sales were 2,767 units, representing 30.1% of sales of the vehicle.
However, Chevrolet is trying to challenge that passenger car diesel hegemony with the compact Cruze Diesel, introduced for MY 2014, and now with a facelift for MY 2015. (Earlier post.) Chevrolet is positioning the Cruze, which features a US-modified 2.0L diesel from GM’s European lineup (the engine is manufactured in Kaiserslautern, Germany) to challenge Jetta on the basis of highway fuel economy and power, as well as content. Based on a week with the car (MY2014), the claimed fuel economy superiority may be tough to realize in real-world driving (especially in the face of the new, more fuel-efficient diesel in the 2015 Jetta, earlier post) but overall, the Cruze Diesel is a worthy challenger, and a very good and thrifty drive, especially on the highway.
Details on GM’s new efficient top-end 8-speed automatic
August 21, 2014
|2015 Hydra-Matic 8L90 (M5U) Eight Speed RWD Automatic Transaxle Click to enlarge.|
GM is offering a version of its new GM-developed Hydra-Matic 8L90 paddle-shift eight-speed automatic transmission in the 2015 Corvette Stingray (earlier post) and Z06. The 8L90, the replacement for the venerable 6L80 six-speed in GM’s lineup, is offered as well as standard on 2015 Chevrolet Silverado, GMC Sierra and GMC Yukon Denali/Yukon XL Denali models equipped with the 6.2L EcoTec3 V-8 (L86) (earlier post), and on the Cadillac Escalade and Escalade ESV. The rated turbine torque capacity of the new transmission is 1000 N·m (738 lb-ft).
GM’s objectives in developing the new 8-speed were improved fuel economy, performance, and NVH—while staying in the footprint of the 6L80. The eight-speed powerflow yields a 7.0 overall ratio spread, enabling improved launch capability because of a deeper first gear ratio and better fuel economy due to lower top gear N/V capability, relative to the 6L80.

Volvo Trucks launches dual-clutch transmission for heavy-duty trucks
June 17, 2014
|I-Shift Dual Clutch provides seamless power delivery. Click to enlarge.|
Volvo Trucks is now launching I-Shift Dual Clutch, the first transmission on the market with a dual clutch system for heavy vehicles. With power-shift gear changes without any interruption in power delivery (with the exception of the range-change, which takes place when shifting from 6th to 7th gear), the 12-speed transmission maintains torque, and the truck does not lose any speed during gear changes. For the driver, the result is more comfortable and efficient progress on the road.
Transmissions with dual clutches are already used in cars, but Volvo Trucks is the first manufacturer to offer a similar solution for series-produced heavy vehicles. Volvo Trucks says that fuel consumption with the base I-Shift Dual Clutch is the same as with regular I-Shift. The company is offering two software packages to improve fuel economy with the unit:
