From a Dezeen.com online review:
On a single charge, Helia can cover a range of 900 kilometres – the distance from London to Edinburgh. Again, compared to the Tesla 3, the Cambridge University team’s car has double the range on a battery a quarter of the size.
The ability to cover this distance is aided by Helia’s chassis and body panels made from carbon fibre, which grant it a kerb weight of 550 kilograms.
Students from Cambridge University have built an ultra-efficient electric car that drives using only as much power as it takes to boil a kettle.
The Cambridge University Eco Racing (CUER) student society built the four-seater car, named Helia, with efficiency as the main goal.
Their achievement has been to produce a car that can travel 80 kilometres-per-hour using only 2500 watts, or as much power as it takes to boil a single kettle, which is equivalent to 31 watt-hours-per-kilometre.
From the outside, the Cowboy e-bike is a sleek bike. It features a seamless triangle-shaped aluminum frame, integrated lights and a low-key Cowboy logo near the saddle. The handlebar is perfectly straight like on a mountain bike. The only sign that this is an e-bike is that the frame is much larger below the saddle.
The B1 and B2 are classified as Class 3 trucks weighing between 10,000 and 14,000 pounds – the same class as a Ford F350 Super Duty. The skin is made of aluminum, but most of the mass comes from the huge battery that will give the truck over 200 miles of electric range while offering the capability to tow a claimed 7,500 pounds or carry 5,200 pounds of payload.
…this prototype is powered by a 10.5 amp hour (AH) lithium battery, which can reach speeds of just over 12 miles per hour and power the vehicle for around 12 miles on a single charge.
The e-bike surprisingly doesn’t look like one, especially given that the rear-wheel motor is concealed from view, and the Flit’s cylindrical battery was designed to beautifully slide into a hollow space inside the bike’s frame, hiding it from view. The bike has a unique way of also integrating suspension into it that allows the rear wheel to easily absorb any shock brought about by cycling on roads, pavements, or even rocky, gravel-y paths. Engineered to perfection by Dave Henderson, who’s background includes being an engineer at Jaguar Land Rover, the Flit-16 maximizes rigidity within a minimal design that further reduces down thanks to its three main hinges that allow you fold or unfold your e-bike in just 10 seconds. 
The SC-1 is designed to transform what was a mere means of mobility into an all-new opportunity for entertainment. Sony and Yamaha Motor will deploy it to provide fun new diversions at venues such as golf courses, amusement parks, and commercial facilities.

The car did what it was supposed to. The ride was a bit shaky, but it’s unclear whether that was because of the vehicle itself or because its AI system was constantly re-evaluating its surroundings. But it felt safe — we slowed down and swerved around a cyclist without leaving the lane. The cars had the entire route mapped out; each destination was already programmed in.
