► 2014 BMW C evolution
With 11 kW continuous output (homologation according to ECE R85 to
determine motor outputs) and 35 kW peak output, the "C evolution" has a
powerful motor and provides a high level of riding fun. The top speed is
electronically limited to 120 km/h. The scooter supremely handles motorway
riding and overtaking - even with a passenger. It is also capable of
effortless hill starts on steep slopes with a pillion passenger. In terms
of acceleration from 0 to 60 km/h, it comfortably holds its own against
current maxi scooters a capacity of 600 cc or more.
Compared to conventional combustion engines, the electric drive of the
"C evolution" also offers significant advantages at low speeds in
particular. Thanks to elaborate power electronics settings, the alternator
offers the rider an instant, spontaneous response. There are no delays in
torque build-up at all as are typical in combustion engines due to the
clutch engaging and disengaging.
At 8 kWh, the storage capacity of the battery is extremely generous and
ensures a range of up to 100 kilometres. This means that realistic
zero-emissions riding in the big city and in urban environments is no
problem at all. As in other areas, BMW Motorrad has been able to draw on
synergy effects with BMW automobiles here. For example, the "C evolution"
uses the same lithium-ion storage modules as are installed in the BMW i3.
Here, developers paid particular attention to the quality and service life
of the storage modules so as to ensure that the range is preserved even
after many years of service life and in very cold weather.
One of the main technological challenges was optimum cooling of the
high-voltage battery. On the one hand it was necessary to avoid excessively
low temperatures due to the fact that the interior resistance of the cells
is heavily increased as a result, thereby reducing power. On the other
hand, the temperatures must not be too high since this would impair the
lifetime of the cells.
While in electrically powered cars a cooling agent is normally used to cool
the battery, air cooling is used in the "C evolution" in order to save
space and weight. The heat of the high-voltage battery is dissipated by
means of an aerodynamically optimised cooling air shaft at the centre of
the battery casing through which there is a constant flow of air. To ensure
optimum heat dissipation, the battery base has longitudinally arranged
However, the battery casing in die-cast aluminium not only holds the cells
with their special architecture but also the entire electronics unit for
monitoring the cells. It also acts as a load-bearing chassis element.
The power electronics for the electric drive is installed behind the
battery casing. This not only takes care of controlling the alternator
within a range of 100 to 150 volts but also responds to rider commands, for
example by detecting the position of the throttle grip. The system also
processes information from the brake system and decides whether energy
should be recuperated and how much recuperation torque is to be applied to
the rear wheel if required.

Top 10 Sports Sedan 2015 (Mid-size Cars / D-segment)
The 6.2L LS3 small-block V-8 is the power behind the Chevrolet
SS’s driving experience. It is SAE-certified at 415 horsepower (310 kW) and 415
lb.-ft. of torque (563 Nm).
Infiniti Q50 S
3.7-liter aluminum-alloy DOHC 24-valve V6 rated at 328hp and 269lb/ft of
Also available is an advanced hybrid powertrain: 3.5-liter 24-valve DOHC
aluminum-alloy V6 and compact laminated lithium-ion battery design with an
innovative one-motor/two-clutch motor control. The system's V6 is rated at
302hp and 258lb/ft of torque, while the advanced 50kW electric motor is
rated at 67hp and 214lb/ft of torque. The hybrid system net power is 360hp,
providing strong acceleration and lean fuel economy.
Subaru WRX STI
The 2015 WRX STI is powered by a 2.5-liter turbocharged/intercooled 4-cylinder BOXER engine
that employs the Dual Active Valve Control System (Dual AVCS). The engine
produces 305 horsepower (SAE) at 6,000
rpm and 290 lb.-ft. of peak torque at 4,000 rpm.
Lexus IS 350 F Sport
The Lexus IS 350 F SPORT is powered by a direct and port injected 3.5 Liter
V6 engine delivering more than 300 horsepower.
Jaguar XE S
Powered by the supercharged 3.0-litre V6 (340 hp) engine from the acclaimed
Jaguar F-TYPE, the XE S is capable of 0-60mph in just 4.9 seconds.
The V6 combines 245 kW (333 hp) of power and 440 Nm (324.5 lb-ft) of
torque. The sedan sprints from 0 to 100 km/h (62.14 mph) in 5.0 seconds.
The Maserati Ghibli has 301 kW (410 hp) of power, races to 100km/h in 5.0
seconds and stretches out to a top speed of 284km/h.
The new engine sees a slight power upgrade over the previous V8 to 431 hp,
which is delivered between 5,390 and 7,000 rpm. Peak torque has been
increased by roughly 40 per cent to 550 Newton metres, and is maintained
over a very wide rev band (1,800--5,390 rpm). The standard sprint from zero
to 100 km/h (62 mph) takes the new BMW M3 Sedan and new BMW M4 Coupe 4.1
seconds respectively. Top speed is 250 km/h / 155 mph (electronically
limited), or 280 km/h / 174 mph if the optional M Driver's Package is
Mercedes C63 AMG
The C 63 produces 350 kW (476 hp), the C 63 AMG S 375 kW (510 hp). The C 63
S accelerates from zero to 100 km/h in 4.0 seconds and the C 63 in 4.1
seconds (Estate: 4.1 and 4.2 seconds respectively).
Dodge Charger Hellcat
The new 2015 Dodge Charger SRT Hellcat is powered by the new supercharged
