Dutch students building a ‘Ring beating hybrid racer

By Peter Braun July 8, 2014

What is wrong with college kids today? In my day our greatest aspiration was to get through class and maybe meet someone pretty. It certainly wasn’t building a race car that hopes to not only win at Le Mans but also beat the all time lap record at the Nurburgring. But that is exactly what students from the Technical University of Eindhoven and the Fontys University of Applied sciences want to do.

The car dubbed the IM01 is being built for the InMotion motorsport company and as you would expect given the goals it should have some pretty impressive technology.

The crucial piece of the puzzle is a hybrid drivetrain that features four electric motors, one at each wheel, powered by batteries, and charged by a rotary engine. Rotaries have been around for a long time, thanks to inventor Felix Wankel and of course Mazda, but they may have finally found their niche in systems like the one proposed by InMotion.

Run at a fixed rpm and used as a generator, rotaries can generate a lot of power very efficiently thanks to lower resistance and vibration. The InMotion team is shooting for 60 percent efficiency (meaning 60 percent of the potential power of the fuel is converted to useful mechanical energy), which might sound low, but the average efficiency of an internal combustion engine is only around 25 percent.

This hybrid system should not only provide plenty of power it should help with handling thanks to the possibility of torque vectoring using the four electric motors to drive each wheel at the correct speed for cornering.

Predictably aerodynamics feature heavily in the IM01’s design. The result looks a bit like the love child of a Tron light-cycle, a land speed record car, and F16 Fighting Falcon. This will no doubt produce more downforce than produced by the cast of Duck Dynasty. There are also some active touches, for instance hot air from the engine is used in a blown diffuser which actively disrupts the air behind the car to create a smoother slipstream.

All of this sounds impressive, but for now it is firmly in the territory of imagination. A project like this will need money, time, and luck to succeed. Especially as the goal set by the team is to compete at Le Mans in 2017. Still I can’t help but hope they succeed.

Mercedes-Benz EQG: range, price, release date, and more

Concept image of the larger electric G-Wagon

The G-Class is going electric. We already knew that Mercedes-Benz was working on an electric, small-size G-Wagon, but it looks like the company is also working on a larger G-Class SUV, in the form of the EQG. In fact, Mercedes has gone as far as to show off a concept version of the off-roader.

While there's much we don't know about what will become the production model of the EQG, Mercedes has also shared a lot about it. Curious about whether the Mercedes-Benz EQG could be the EV for you? Here's everything we know so far.
Design
Fear not -- the EQG will retain many of the design aspects of the G-Class that you already know and love but with a modern face-lift. The EQG will keep the boxy design that gives the G-Class a classic look but with some additional modern styling, at least if the concept version is anything to go by.

Rivian R2 vs. Kia EV9: battle of affordable electric SUVs

Kia EV9 GT-Line Three Quarters

The long-awaited Rivian R2 has finally been announced, and it's an excellent option for those who want an electric SUV that doesn't completely break the bank. Sure, the R2 isn't cheap -- but it's a whole lot cheaper than most other EVs out there, especially when it comes to SUVs. But Rivian isn't the only company trying to tackle the problem of the budget electric SUV. The Kia EV9 is finally available, and it too offers a modern design and a range of helpful features.

Given the fact that the Rivian R2 and Kia EV9 are two electric SUVs in a similar price range, you might be wondering which is better for your needs. That's why we put the Rivian R2 and the Kia EV9 head-to-head.
Design
Both the Rivian R2 and the Kia EV9 are actual SUVs -- not crossovers pretending to be SUVs, like plenty of other EVs out there. The two vehicles offer big, boxy designs and plenty of interior space, making them excellent options for families or those who need that extra storage.

Rivian R2 vs R1S: How will Rivian’s cheaper SUV compare?

The front three-quarter view of a 2022 Rivian against a rocky backdrop.

Rivian has finally unveiled the R2, its long-awaited attempt at a more affordable electric SUV. The new vehicle may not be available just yet, but fans of Rivian's design aesthetics and feature set are already looking forward to being able to order the new car. The R2 is targeted at being a more affordable take on the electric SUV and will sit alongside the flagship-tier R1S.

Let's get this out of the way right now: The R1S is most likely going to be a better vehicle than the R2. Rivian isn't replacing the R1S with the R2 — it's releasing the R2 as a more affordable alternative, and there will be some compromises when buying the R2 over the R1S.
