If you follows Mercedes-Benz news, you may have already known that for the 2015 model year, there is no more “550” model for the E-class and M-class. Also gone with the E550/ML550 will be the 4.6L twin-turbo V8 engine. The replacement for the E550 and ML550 will be the E400 and ML400, respectively.

The E400 and ML400 will be powered by a 3.0L twin-turbo V6 engine, good for 329 hp and 354 lb-ft of torque. For the output numbers, this is a downgrade. For your reference, the V8 on the E550/ML550 has 402 hp and 443 lb-ft of torque.

Not only the 2015 E400/ML400 has lower power output than the 2014 E550/ML550, but the ML400 is even more expensive than the ML550...

Today there was a rumor that surfaced online that the next generation Corvette may have a mid-engine layout, or will have a mid-engined variant.

First let’s make it clear that Chevrolet does produce a mid-engined Corvette. However, here “a mid-engined Corvette” means Chevy actually only made one unit of such a Corvette, which is the Corvette Daytona Prototype, which Chevrolet created specifically for the 2012 Daytona race. Below are images of this Corvette.

Corvette Daytona Prototype is not a production car, and Chevrolet has no plan to make it a production car, plain and simple.

The fact is, beginning 3 generatio...

2014 Acura RDX – Part 3 (Interior – Gauges/Seats/Capacity)
2014 Acura RDX – Part 4 (Powertrain)
2014 Acura RDX – Part 5 (Suspension and Chassis)

Two things impressed me most when testing the RDX are: the ride comfort the suspension provides, and also the solidness of the car chassis.

First I will talk about the suspension. For the RDX, the front suspension is MacPherson strut type, and multi-link for the rear suspension.

A close look at the multi-link suspension in the rear wheel area. The majority of the rear wheel suspension parts are made of steel.

The 2014 RDX only has one engine option: a 3.5L naturally aspirated V6, good for 273 hp @ 6,200RPM and 251 lb-ft of torque at 5,000 RPM. Also there is only one transmission is available on the RDX: a Honda-self-developed 6-speed automatic transmission.

Let’s first talk about the V6 engine (Honda code name: J35Y)...

Since Dodge can do a SRT Hellcat trim for the Challenger, there is no technical issue that will prevent Dodge from putting the same powertrain in any of its rear-wheel-drive models.

So obviously we are not surprised that now Dodge has announced the 2015 Charger SRT Hellcat with the same 707hp engine. For more technical discussion of this supercharged 6.2L V8 engine, please see our article here. If you do not have time to go through the press release provided in the end of this article, here are some key highlights of this sedan monster.
