Zytek Automotive, a UK-based company, is developing an all-new electric vehicle powertrain, and the company says that the third-generation design - which is built from a clean slate - will significantly simplify the introduction of next-generation electric vehicles, be it niche models or high-volume global vehicles.
The 25kW Zytek EV powertrain.
The modular package, available in sizes from 25kW, is extremely compact, and in air-cooled configuration, is up to 45% lighter than today’s production EV powertrains, while the water-cooled version, suitable for demanding drive cycles, is still up to 30% lighter.
Features in the powertrain include the integration of the charger within the inverter, reducing the number of separate enclosures and connectors required in the vehicle, and a new, high-efficiency permanent magnet synchronous motor offering a maximum speed of 14,000rpm, providing oodles of generated torque while keeping the machine's size small and weight low.
A closer view of the motor plus transmission.
A new transmission, designed specifically for use with the new powertrain, is being developed by transmission specialist Vocis, and offers compactness (just 138cm wide) and lightness (10kg) among its key features.
The compact dimensions of the new drivetrain will make mechanical integration with a vehicle much simpler. The main connections required are high voltage (to the traction battery) and low voltage (for electrical interface with the vehicle). The air cooling option adds to the weight reduction and reduces complexity by eliminating the entire water cooling system.

VW launches new Polo GTI

Volkswagen has launched the GTI variant for its new Polo hatch; the little rocket has 178bhp, like its predecessor, though this is achieved with the use of a turbocharged and supercharged 1.4l TSI block compared to the 1.8l turbo unit on the previous one.
Effectively, this amounts to the same level of performance and fun, with the 1,194kg vehicle able to do the 0-100kmh sprint in 6.9secs and get to a top speed of 229kmh, but with a 25% improvement in fuel efficiency .
The car is equipped with a 7-speed dual clutch gearbox (DSG) as standard; an electronic transverse differential lock (XDS) reduces the tendency to understeer and improves handling aspects. Like all versions of the model series, the Polo GTI also comes equipped with ESP, including Hill Climb Assist.
Safety equipment includes an airbag network that features combined head-thorax side airbags, belt tensioners, belt tension limiters plus belt warning, front head restraints designed to avoid whiplash trauma as well as Isofix points on the rear bench seat.
As for convenience, items on the kit list include electro-hydraulic power steering, central locking, bootspace lighting and tie-down eyes, driver seat height adjustment and green-tinted insulated glass.
The Polo GTI is the first Polo to come with bi-xenon headlights with cornering lights, LED daytime running lights and corner marker lights, as well as a panoramic tilt/slide sunroof. GTI-specific features include a sport seat system and 17-inch Denver alloy wheels.
