8 Cars Similar to the BMW Z4 Roadster

Side view look of BMW Z4 Roadster car in a yellow color at car show.

Car and Driver never give out a rating of 10, but you know you found a winner when you spot a nine in its rankings. That’s what the venerable magazine awarded the BMW’s latest incarnation.

The automaker, long known for its luxury vehicles and exotic designs, brought all of its knowledge together to build the BMW Z4 Roadster, which looks like a jaunty James Bond-ish ride on the inside and outside. This gorgeous car appears racy in red or sleek and sophisticated in silver. Its basic black isn’t basic.

What makes it the winner of the luxe set, clearly comes down to price and performance. It doesn’t just provide looks. The lovely convertible starts at $49,900 and offers an upgraded version for $63,700.

The Roadster may seem to be in a class by itself, but it does have in-class competitors. BMW crafted a gorgeous gas-powered commuter car with an extra dose of class in the Z4 Roadster. Its entry-level vehicle earns 25 mpg in the city and 32 mpg on the highway.

That might not sound impress now that people became accustomed to electrics, but this amazing vehicle should appreciate if it performs like its brethren. It could be one of the company’s last gas-powered roadsters, too, since some US states, such as California have already instituted a deadline by which automakers can only offer electrics.

This vehicle then could become one of the last of the Mohicans as the old saying goes. It doesn’t guzzle gas with its 2-liter, four-cylinder engine produces 255 horsepower and 295-pound feet of torque. Paired with an eight-speed automatic transmission and rear-wheel driveline, you can tool around town in style and within budget.

It manages to go from 0 to 60 in 3.8 seconds, beating out the Porsche Boxster S and its 350 horsepower engine. While most car buyers probably don’t think in terms of collection building, if you do plan to keep a car and add it to a growing garage, this roadster could make an ideal choice. You can use it now and bank on it going up in value.

Because the manufacturer cared about fuel efficiency, you can drive a speedy convertible sports car without it costing a lot to fill up. If you do mostly highway driving, such as for a commute, you can expect to save money driving this vehicle versus most other sports cars.

While you probably aren’t planning to haul lumber if you typically drive a sports car, you can grocery shop in this vehicle. It offers a 9.9 cubic feet trunk. If that sounds tough to visualize, think of a chest freezer. They’re the same size. That’s plenty big enough for a family’s groceries for a week or so and the dry cleaning.

Considerations When Buying a Roadster

On a warm day with Autumn Park in the background, a red BMW Z4 is parked on the street.

Buying a sports car and buying a roadster don’t mean the same thing automatically. That’s because many sports cars today offer a sports car design with four doors. That means you can seat four people or five.

The current Mustang design falls into the four seating capacity category. You can also get a Mustang that seats four but has two doors. A roadster only seats two people.

The word means a two-seater car meant for driving long distances. In the earliest days of vehicles, most cars were roadsters. It falls into the broad category of sports cars.

They typically go a bit faster and sport smaller trunks. You won’t see massive trunks on a roadster like those on a sedan. This means they make the ideal car for a single person or a couple without children.

They won’t work as a family car though. If you travel a lot on business and need to haul travel cases or tri-fold backdrops, such as those used at conferences and conventions, this type of car wouldn’t work. It has no backseat to fold down. The front two seats – usually bucket seats – provide the only seating area.

The only storage resides in the trunk. The storage tops out at ten cubic feet – the size of a free-standing chest freezer.

Frequently Asked Questions About Buying a Roadster

Everybody’s got questions when they shop for a new vehicle. That’s normal. This FAQ addresses the most common questions by people when trying to decide which sports car to buy.

How much horsepower do you need?

Is this your first vehicle purchase? Horsepower only matters if you really need it. When you use a vehicle to haul groceries or plants home from the store, you can have a vehicle with any horsepower. When you need to haul equipment, a boat, a camper, a trailer, or construction materials, you need horsepower.

The higher the horses, the more powerful the engine. So, all things considered, an engine that produces 300 horsepower works better than an engine that produces 175 horsepower. If you need fuel efficiency, typically, you should choose a smaller, less powerful engine because they usually get better gas mileage.

The term comes from the time before automotives. In the old days, horses drew carriages and trailers. When the auto got invented, its purveyors compared its engine performance to the number of horses required to haul the same amount of people and stuff.

Here’s the thing. Size and vehicle design also contribute to ability of a vehicle to tow. Roadsters aren’t meant to tow vehicles.

What do you typically tow?

A close-up photograph of a BMW Z4 roadster with a camouflage color scheme is displayed on the street.

If you typically tow anything, then a roadster isn’t your vehicle. Sedans can tow lower-weight items, but roadsters cannot. Their design isn’t intended for that.

The reverse works though. You can tow these small, lightweight vehicles. Let’s say you’re moving across country and need to drive.

You will probably save money by towing your roadster with your SUV or truck instead of gassing up both vehicles and driving them. Because roadsters weigh so little – typically less than 2,500 pounds of curb weight, you can easily tow them with a mid-sized truck or a moving van.

If you own or rent a truck that can tow up to 7,000 to 10,000 pounds, you can use a long trailer and tow both your boat and your roadster with the same vehicle.

Do you need a two- or four-wheel drive?

Some sports cars offer four-wheel drive but that’s typically higher-end vehicles. Most cheaper sports cars either offer rear-wheel or all-wheel drive. If you buy a roadster for the driving pleasure and want to race it, you need to look for a vehicle with four-wheel drive instead of all-wheel drive.

The two terms don’t mean the same thing. The four-wheel drive lets you control the front and rear wheels separately with your steering because of the axle design beneath. An all-wheel-drive design differs because you move all four wheels at one time in the same direction.

With four-wheel drive, the rear and the front wheels can move independently. That isn’t the case with all-wheel drive.
