COVER STORY: TRAILER SPECIAL
The missing link
Today’s articulated heavy vehicles, sophisticated as they
might be, cannot function without reliable ‘suzie’ connections
between truck and trailer, reports Lucy Radley

Putting meat on the bones
Skeletal trailers are available from many manufacturers and
in many options, each with its own characteristics

Bucking the trend
UK trailer makers have been investing heavily in bigger
premises, smarter manufacturing and new products. But will
Brexit throw a spanner in their works, asks Brian Weatherley

lectric vehicles were the major theme at both of the season’s bus
exhibitions: Coach & Bus (pp22-23) and Busworld (pp10-11).
Driven by government restrictions on diesel vehicles in urban
areas to help improve air quality, many manufacturers are
previewing new models of battery-powered vehicles.
Outside of London, however, the regulatory picture is
complicated. As each local authority can set its own rules, not every
low-emission zone is created equal. Although some are indeed
setting up zero-emission zones, even those are unlikely to spread
as wide as London’s. Many air quality zones do not penalise diesels,
provided they comply with Euro VI standards.
At the moment, full-electric vehicles remain uncommon, expensive
to buy, limited in range, and difficult to integrate into fleet operations.
For all of these reasons, a full-electric future is not necessarily the
destiny of even the most electricity-friendly applications, such as
urban buses and distribution trucks – not to speak of haulage.
Two other low-carbon alternatives, both available now, are
profiled in this issue. One is gas powertrains (pp43-45). Although
offering little carbon footprint reduction in its fossil fuel form than
diesel, methane (CNG) gas engines do emit less air pollution that is
harmful to people. Some CV and bus operators, such as in Reading,
Nottingham and Bristol, have taken on significant gas fleets.
The other is hybrid powertrains (they were also covered last
month: see
www.is.gd/reguhu).
BAE Systems’ hybrid electric
powertrain platform for buses, which does include a diesel engine,
can operate engine-off to various extents, depending on the model’s
capacities. Its operation in Brighton is highlighted, pp26-27.
As full-electric vehicle models from the major manufacturers
come to market in the next few years, it will be interesting to see
whether they can compete with solutions like these.
