Remembering the Tragedy of the Titanic
When the Titanic was completed on April 2, 1912, it was the largest and perhaps most luxurious ship in the world. The vessel could hold over 3,300 people including crew members, and boasted various amenities including a swimming pool and squash court.
The Titanic’s impressive size attracted many of the world’s wealthiest individuals, and on April 10, 1912, it set out on its maiden voyage. Just five days later, the ship sank after hitting an iceberg, resulting in more than 1,500 deaths.
It’s been over 100 years since the Titanic’s demise, so how have passenger ships evolved?
To find out, we’ve visualized it beside Royal Caribbean’s Symphony of the Seas, currently the world’s largest cruise ship.
The Size of the Titanic, in Perspective
The following table lists the dimensions of both ships to provide a better understanding of the Titanic’s relative size.
|RMS Titanic||Symphony of the Seas|
|Length||882ft (269m)||1,184ft (361m)|
|Width||92ft (28m)||215ft (66m)|
|Height||175ft (53m)||238ft (73m)|
|Internal volume||46,328 gross register tonnage (grt)||228,081 gross tonnage (gt)|

Note: Gross register tonnage (grt) is a historic measure of a ship’s internal volume. This metric was replaced by gross tonnage (gt) on July 18, 1982.
One of the biggest differences between these two ships is width, with the latter being more than twice as wide. This is likely due to the vast amenities housed within the Symphony of the Seas, which includes 24 pools, 22 restaurants, 2 rock climbing walls, an ice-skating rink, and more. With accommodations for 6,680 passengers, the Symphony of the Seas also supports a crew that is 147% larger.
The Symphony of the Seas clearly surpasses the Titanic in terms of size, but there’s also a substantial difference in cost. When converted to today’s dollars, the bill for the Titanic equates to roughly $400 million, less than half of the Symphony of the Seas’ cost of $1.35 billion.
Lessons Learned from the Disaster
Inadequate safety preparations were a contributor to the Titanic’s high death toll. During its journey, the vessel carried enough lifeboats to accommodate just 33% of its total passengers and crew. This was legal at the time, as regulations based a ship’s number of required lifeboats on its weight, rather than its passenger capacity.
To make matters worse, investigations determined that the Titanic’s lifeboats had not been used to their full capacity, and that a scheduled lifeboat drill had been cancelled by the ship’s captain. These shortfalls, among others, paved the way for numerous improvements in maritime safety regulation.
These include the creation of the International Convention for the Safety of Life at Sea Treaty (SOLAS) in 1914, which is still in force today. Regarded as the most important international treaty on ship safety, SOLAS has been updated numerous times and is followed by 164 states, which together flag 99% of merchant ships (by gross tonnage) on the high seas today.
The Most Fuel Efficient Cars From 1975 to Today
This infographic lists the most fuel efficient cars over the past 46 years, including the current leader for 2023.
The Most Fuel Efficient Cars From 1975 to Today
When shopping for a new car, what is the most important factor you look for? According to Statista, it’s not design, quality, or even safety—it’s fuel efficiency.
Because of this, automakers are always looking for clever ways to improve gas mileage in their cars. Beating the competition by even the slimmest of margins can give valuable bragging rights within a segment.
In this infographic, we’ve used data from the EPA’s 2022 Automotive Trends Report to list off the most fuel efficient cars from 1975 to today.
Editor’s note: This is from a U.S. government agency, so the data shown skews towards cars sold in North America.
All of the information in the above infographic is listed in the table below. Data was only available in 5-year increments up until 2005, after which it switches to annual.
|Model Year||Make||Model||Real World Fuel Economy (mpg)||Engine Type|
From this dataset, we can identify three distinct approaches to maximizing fuel efficiency.
Prior to 2000, the best way for automakers to achieve good fuel efficiency was by downsizing. Making cars smaller (lighter) meant they could also be fitted with very small engines.
For example, the 1985 Chevrolet Sprint was rated at 49.6 MPG, but had a sluggish 0-60 time of 15 seconds.
The 2000s saw the introduction of mass-market hybrid vehicles like the Honda Insight and Toyota Prius. By including a small battery to support the combustion engine, automakers could achieve good MPGs without sacrificing so heavily on size.
While the Insight achieved better fuel economy than the Prius, it was the latter that became synonymous with the term “hybrid”. This was largely due to the Prius’ more practical 4-door design.
The following table compares annual U.S. sales figures for both models. Insight sales have fluctuated drastically because Honda has produced the model in several short spans (1999-2006, 2009-2014, 2018-2022).
|Year||Insight Sales||Prius Sales|
The Prius may have dominated the hybrid market for a long time, but it too has run into troubles. Sales have been declining since 2014, even setting historic lows in recent years.
There are several reasons behind this trend, with one being a wider availability of hybrid models from other brands. We also can’t ignore the release of the Tesla Model 3, which began shipping to customers in 2017.
We’re currently in the middle of a historic transition to electric vehicles. However, because EVs do not use fuel, the EPA had to develop a new system called MPGe (miles per gallon of gasoline-equivalent).
This new metric gives us the ability to compare the efficiency of EVs with traditional gas-powered cars. An underlying assumption of MPGe is that 33.7 kilowatt-hours (kWh) of electricity is comparable to the energy content of a gallon of fuel.
The most fuel efficient car you can buy today is the 2023 Lucid Air, which achieves 140 MPGe. Close behind it is the 2023 Tesla Model 3 RWD, which is rated at 132 MPGe.
